I also know that I cannot tell the difference between two IPv6 addresses because they all merge into an indiscernible blur inside my head
Back when we had to dial ipv4 addresses from memory
However I can see when any IPv6 begins with 2a02:12xx:: then it's Swisscom (biggest swiss ISP). But I can't remember any of their hundreds of IPv4 prefixes.
I have a feeling making it all CAPS would have made it just a bit easier.
That, or using monospace fonts for it everywhere.
I recite IPv6 addresses on my company networks from memory all the time. It helps that we got a bit lucky on our allocation. There are no letters.
Plus it's really easy to number subnets in a way that makes sense.
::1 is the new 127.0.0.1
:: abbreviates empty fields
ipv6 has more addresses
there is something going on with mac addresses (asside from arp)
thats all i remember
fd00:: is the new 192.168
~~fc00::/7 are ULA (basically what RFC1918 was for IPv4)~~ not entirely true, fc00::/8 is part of ULA, but it is not yet defined. Use fd00::/8 instead.
2001:db8::/32 is for documentation purposes
IMO they shouldn't have allowed ULA as part of the standard. There's no good reason for it.
I use ULA prefixes to ensure the management interfaces of my devices don’t leak via public routes.
It’s one of the unique parts of the standard IPv6 stack not back ported to IPv4, that an interface on any host can be configured with multiple addresses. It permits functional isolation with the default routing logic.
IPv6 is far from perfect, but the majority of the arguments I’ve seen against deploying it are a mixture of laziness, wilful ignorance, and terminal incuriosity.
Yeah there is: not breaking all your internal traffic when the wan link goes down and you lose your prefix.
When you want IPv6 but your ISP says “no”
I keep hearing this, and I KNOW it's true at the enterprise level, but I've been running my home LAN IPv6 native for the last - 6+ years? Ever since I learned Comcat would vend it to you from their stock router.
Works great. No problems. Didn't used to be that way, but these days most (more?) of the stack bugs have been shaken out.
I'm a network engineer and I run ipv6 natively in all of our datacenters. There are even a handful of end systems that have ipv6 native networking stacks with ipv4 sockets for our non-ipv6 compatible applications. IPv6 issues are basically self-inflicted at this point by companies that see their IT systems as cost centers, or by basilisk directors who's knowledge stopped in the 90's.
I am hosting a few services on my LAN over IPv6, except for Plex, which I am tunneling through IPv4, since Plex itself used to have issues with IPv6.
It's always funny when friends complain that one of my services is down, it was 100% IPv6 not working/enabled/willingly disabled on their site yet.
I made an effort to learn it. In 2000. Again in 2012 or whenever the last big push was. If past is prologue, I may need to learn it again soon. 😆
Ah, Dutch directness... Nothing says clear communication louder than the Dutch
It's an edited image, but you are darn right. Proper communication is great
It is in the style of the original, where during Covid the page on “Migrating to the Netherlands” simply just started with “Do not migrate to the Netherlands”, before expanding on the Covid restrictions on place and what foreign nationals currently in the Netherlands are to do.
On one hand: Now that's loud & clear communication. On the other hand, “Just don't” really ties in to the stereotype of Dutch directness/rudeness.
