Re: The real reason nobody wants to use it

Not sure why they thought that would be a good idea.

Actual I think multiple addresses is a good idea.

1. The FE80::/7 is the former 169.254, always active, used for "same link" things, to some extend it replaces ARP, prevents ARP storms by design. Has the MAC coded into the address.

2. The FEC0::/10 (usually subnetted in /64 packets), similar to 192.168.x.x, but no "default gateway" for Internet desired, only clear other LAN destination routes.

3. The FC00::/7 (usually subnetted in /64 packets), similar to 10.x.x.x, but no "default gateway" for Internet desired, only clear other LAN destination routes.

4. The FD00::/8 DO NOT USE (usually subnetted in /64 packets), similar to 172.16.x.x, but no "default gateway" for Internet desired, only clear other LAN destination routes. This got removed from the standard somewhere in the last 20 years and replaced by FC00::/7 which included FD00::/8, therefore better avoid.

5. The FF00::/8 is multicast, similar to the 224.x.x.x

6. Finally the actual internet address, usually 2001:whateverfirst64bits:your-pseudo-static-part. Depending on the provider your prefix might be /56 /48 as well. The yourpseudosstaticpart is, on many devices, optionally with privacy extensions, so they are random and change over time even if your provider does not force-disconnect-reconnect. How much "privacy" that offers is a discussion for another decade.

Normal homes have 1 and 6. Über-Nerd homes or companies with somewhat clean ipv6 adaption have 1, 2 or 3 (not both please!), and 6 to organize their WAN/LANs. Enlightened Nerds include 5 too.

2 and 3 have the advantage that they are DEFINETLY not to be used for internet, no gateway to the internet, and therefore safe for LAN. I am nerd, but don't give a s, so I have 1 and 6, and my fd address is there for historic reasons since I played with ipv6 over a decade ago but not active in use.

My gripe is a lot of the things around it which makes ipv6 a hassle, especially when your prefix from 6 changes, all you adapters, and I mean ALL ACROSS YOUR WHOLE LAN, have to automatically follow suit. Which means: When connected to the Internet a lot of formerly static ipv4 configuration cannot be static any more - unless your provider gives you a fixed ipv6.

This is one of the worst parts of it. And even if your provider gives you a static assignment, what happens when you change provider? Or if you failover on a multi wan connection? Or even try to load balance on a multi wan connection?

The only way IPV6 can be used with the same (even better) flexibility of v4 is when you own you v6 addresses and use a dynamic routing protocol, which is not what a small business usually does. A home user even less.

Then there is the security nightmares v6 can give you. I can't even imagine how many ways of abusing it are simply yet to be discovered, apart from the obvious ones like the fact that even if you don't use v6 to connect to the internet, you LAN has FE80 addresses all around and you have to firewall the hell out of it unless you want someone that penetrated the LAN to use them to move laterally almost for free.

Re: The real reason nobody wants to use it
fec0::/10 is long deprecated, and it's a bit odd to tell us to avoid fd00::/8 in favor of fc00::/7 when the latter includes the former. fc00::/8 is intended for /48s assigned by some central entity (but none has been set up, since there doesn't seem to be a pressing need for one) and fd00::/8 is for people to select their own random /48s from, so if you want to use ULA then you'll be picking a /48 from fd00::/8.

It's not exactly hard to hand out a new prefix to everything. Your router advertises the new subnet, and every machine across your whole LAN receives it and automatically configures a new IP from it.

Anything that assumes your IPs are never going to change is already broken. Maybe we should focus a teeny bit of the energy we spend complaining about it into fixing the brokenness?

//

Most of your first questions can be broadly answered by a mix of "you advertise a /64 from the prefix that the provider gives you" and "you can use multiple addresses". And it doesn't sound like your use of v4 is very flexible if it can't handle your IPs changing sometimes.

less than half of all netizens use IPv6 today.

To understand why, know that IPv6 also suggested other, rather modest, changes to the way networks operate.

"IPv6 was an extremely conservative protocol that changed as little as possible," APNIC chief scientist Geoff Huston told The Register. "It was a classic case of mis-design by committee."

And that notional committee made one more critical choice: IPv6 was not backward-compatible with IPv4, meaning users had to choose one or the other – or decide to run both in parallel.

For many, the decision of which protocol to use was easy because IPv6 didn't add features that represented major improvements.

"One big surprise to me was how few features went into IPv6 in the end, aside from the massive expansion of address space," said Bruce Davie... //

Davie said many of the security, plug-and-play, and quality of service features that didn't make it into IPv6 were eventually implemented in IPv4, further reducing the incentive to adopt the new protocol. "Given the small amount of new functionality in v6, it's not so surprising that deployment has been a 30 year struggle," he said. //

While IPv6 didn't take off as expected, it's not fair to say it failed.

"IPv6 wasn't about turning IPv4 off, but about ensuring the internet could continue to grow without breaking," said John Curran, president and CEO of the American Registry for Internet Numbers (ARIN).

"In fact, IPv4's continued viability is largely because IPv6 absorbed that growth pressure elsewhere – particularly in mobile, broadband, and cloud environments," he added. "In that sense, IPv6 succeeded where it was needed most, and must be regarded as a success." //

APNIC's Huston, however, thinks that IPv6 has become less relevant to the wider internet.

"I would argue that we actually found a far better outcome along the way," he told The Register. "NATS forced us to think about network architectures in an entirely different way."

That new way is encapsulated in a new technology called Quick UDP Internet Connections (QUIC), that doesn't require client devices to always have access to a public IP address.

"We are proving to ourselves that clients don't need permanent assignment of IP address, which makes the client side of network far cheaper, more flexible, and scalable," he said.

There were no pre-game speeches or waving banners; the vets surrounded the jail, demanding access to those ballots.

In response, one side started shooting, and the other answered in kind. The gunfight lasted a couple of hours until the door to the jail opened, giving the ballots a breath of fresh air.

When all eyes could see, the counting resumed.

Consequences, Not Chaos
Unsurprisingly, the slate of GIs won their respective elections — no race was even close — and the corrupt regime lost its grip of control.

There wasn't a loss of life, nor did Athens descend into anarchy; it simply corrected course.

Corrupt authority retreated into the darkness because ordinary people refused to accept theft disguised as governance. //

Despite the desire to paint corruption in postwar America as a foreign disease, Athens was the horn that woke everybody else, illustrating how civic rot grows fast when oversight vanishes, and fear replaces accountability.

Sunshine, as always, is the best disinfectant, so trust returned just as fast when that sunlight exposed everything.

Remember, those men were veterans returning from organized chaos and brutality, and when they returned home, they didn't want to see echoes from the battlefields. All they wanted was a count that matched the vote, while their restraint was just as important as their resolve. //

Across American life, a rope lies across everyone's waist, stretching between trust and force: Keep it slack enough for the law to work and tight enough to stop abuse.

Athens (TN) found its balance when patience was exhausted, and determination emerged.

Colloquialisms rarely announce themselves; they slip into sentences wearing work boots and faded jackets, and are already comfortably broken in.

Writers use them because they sound human, readers accept them because they feel familiar, but familiarity, as the expression goes, comes with a cost. Some phrases have been used so much that they have been rubbed as smooth as the Blarney Stone from overuse, drained of texture by repetition and reduced to verbal placeholders.

Language doesn't fail when people repeat things; it fails when people stop thinking about it.

What follows isn't a glossary or something intended for display; it's simply a working map of expressions that came from real places, by honest labor, real danger, and habits. Some deserve a rest, while others keep earning their keep. A few belong to a specific region or generation and lose force when lifted out of context.

“Really Simple Licensing” makes it easier for creators to get paid for AI scraping. //

Leading Internet companies and publishers—including Reddit, Yahoo, Quora, Medium, The Daily Beast, Fastly, and more—think there may finally be a solution to end AI crawlers hammering websites to scrape content without permission or compensation.

Announced Wednesday morning, the “Really Simple Licensing” (RSL) standard evolves robots.txt instructions by adding an automated licensing layer that’s designed to block bots that don’t fairly compensate creators for content.

Free for any publisher to use starting today, the RSL standard is an open, decentralized protocol that makes clear to AI crawlers and agents the terms for licensing, usage, and compensation of any content used to train AI, a press release noted.

So, about the way Cholesterol guy ...improved his “mental clarity.”

I had a cardiac event in 2010, recovered fine with a bunch of meds, but found that I felt substantially diminished mental reasoning.
I went through a pile of tests, MRI, expert neurologists and cognitive testing, which all amounted to "you're pretty smart", but I just couldn't think like I used to.

In 2018 I got a new general practitioner and mentioned this, and she instantly suggested my cholesterol was too low, that the brain needs a level of cholesterol to function well and she'd seen it repeatedly before that cardiologists "overcook" cholesterol management.

Over a few months she reduced my lipid dosage to a quarter of what it had been, with fairly immediate mental improvements and cholesterol readings still in safe bounds.

I'm pleased to have my brain back despite the experts missing it all, and now I know I can go on the "nine pounds of cheese" diet for a brain boost...

And now, with that redesign having been functional and stable for a couple of years and a few billion page views (really!), we want to invite you all behind the curtain to peek at how we keep a major site like Ars online and functional. This article will be the first in a four-part series on how Ars Technica works—we’ll examine both the basic technology choices that power Ars and the software with which we hook everything together.

Type of Extinguisher Effectiveness on Lithium-ion Fires

• Water ⚠️ Not effective
• Foam ⚠️ Risky; can spread fire
• DCP (Dry Chemical Powder) ✅ Better, but not always reliable
• Specialized Lithium Iron Extinguishers ✅ Most effective!

Class D extinguishers are designed specifically for flammable metals, making them effective against lithium battery fires. Other types, like CO2 and foam extinguishers, can be used in some cases but may not always be effective. Always check labels for proper use.

• Class D extinguishers: Best for lithium fires.
• CO2 extinguishers: Good for electrical fires, but not always effective on lithium.
• Foam extinguishers: Work for some flammable materials, but avoid lithium.

"Worst prank ever"?

at least for a few moments, because the phone soon rang.

"It was the Australian office, laughing their heads off..."

Ah, what they should have done, instead of just hanging up the phone at local midnight, is babble something incoherent about "my god... the koalas... wallabies... they've got machetes... oh the humanity... oh nooooo, the 'roos have taken Clyde..."

And then hung up the phone. //

My y2k horror story.
I sat in a lonely office in Redwood City for a couple hours before and after midnight, playing with Net Hack[0]. My phone didn't ring once. As expected.

The cold, hard reality is that I and several hundred thousand (a couple million? Dunno.) other computer people worked on "the Y2K problem" for well over 20 years, on and off. Come the morning of January 1st, 2000 damn near everything worked as intended ... thus causing brilliant minds to conclude that it was never a problem to begin with.

HOWever, in the 2 years leading up to 2000, I got paid an awful lot of money re-certifying stuff that I had already certified to be Y2K compliant some 10-20 years earlier. Same for the embedded guys & gals. By the time 2000 came around, most of the hard work was close to a decade in the past ... the re-certification was pure management bullshit, so they could be seen as doing something ... anything! ... useful during the beginning of the dot-bomb bubble bursting.

Quite an achievement for seven year old software that used four digit years from the start.

Now let's meet a reader we'll Regomize as "Rob" who at the time of Y2K worked for Sun Microsystems in the UK.

As a global company, Sun had an early warning system for any Y2K problems: Its Australian office was 11 hours ahead of the UK office, so if any problems struck there, the company would get advance notice.

Which is why, as midnight neared Down Under, Rob's boss called Sun's Sydney office … then heard the phone line go terrifyingly silent as the clock ticked pas midnight. Rob said that "scared the hell out of my manager" – at least for a few moments, because the phone soon rang.

"It was the Australian office, laughing their heads off," Rob told On Call. ®

Yakisugi is a Japanese architectural technique for charring the surface of wood. It has become quite popular in bioarchitecture because the carbonized layer protects the wood from water, fire, insects, and fungi, thereby prolonging the lifespan of the wood. Yakisugi techniques were first codified in written form in the 17th and 18th centuries. But it seems Italian Renaissance polymath Leonardo da Vinci wrote about the protective benefits of charring wood surfaces more than 100 years earlier, according to a paper published in Zenodo, an open repository for EU funded research. //

Leonardo produced more than 13,000 pages in his notebooks (later gathered into codices), less than a third of which have survived. //

In 2003, Alessandro Vezzosi, director of Italy’s Museo Ideale, came across some recipes for mysterious mixtures while flipping through Leonardo’s notes. Vezzosi experimented with the recipes, resulting in a mixture that would harden into a material eerily akin to Bakelite, a synthetic plastic widely used in the early 1900s. So Leonardo may well have invented the first manmade plastic. //

The benefits of this method of wood preservation have since been well documented by science, although the effectiveness is dependent on a variety of factors, including wood species and environmental conditions. The fire’s heat seals the pores of the wood so it absorbs less water—a natural means of waterproofing. The charred surface serves as natural insulation for fire resistance. And stripping the bark removes nutrients that attract insects and fungi, a natural form of biological protection.

Big anniversaries are coming up in 2026: 200 years since the deaths of Thomas Jefferson and John Adams, 250 since the signing of the Declaration of Independence, 250 since Adam Smith published “The Wealth of Nations.”

But an anniversary this month deserves special attention, too — Dec. 16 marked 250 years since the birth of Jane Austen, one of the greatest novelists who’s ever lived.

She’s still read today, and millions of people who’ve never so much as peeked into the covers of “Pride and Prejudice,” “Sense and Sensibility” or “Emma” know Austen’s stories from their film and television adaptations. //

Like the Declaration of Independence and “The Wealth of Nations,” her works have stood the test of two centuries and more for a reason.

They are grounded in truths about human nature, and those truths are expressed in ways that enchant as well as instruct.
