I am so surprised by the hate for IPv6 in this thread. I have been deploying IPv6 for more than ten years and it really improve many situations (beside larger addresses). I have to admit, there is a learning curve. But I want to encourage everybody involved in configuring computers to learn. Also I want to rent about Cisco not using /64 for link local by default, thus being incompatible with BSD systems. Link local m…

You’d think so, but dns magically works for me. Wish I had a better answer ha ha.

I assume it's possible to prevent machines from changing their IP address? I have a few where DNS cannot reasonably be used and I use raw IP addresses instead.

What problem is not solved by various DNS and local-addressing options, but is solvable by some other aliasing scheme that isn't DNS under another name, and can you outline how a better aliasing scheme would work? Background and current options, as I'm aware of them: "IPv6 addresses are too difficult" objectors don't seem to want a solution to the ease-of-use problem that leverages aliases, because DNS is that. They…

Solved you say? So how do I set up DNS for LAN hosts that under IPv4 would have static private addresses? Under IPv6, you run into problems long before DNS - trying to assign static addresses as DHCPv6 is an afterthought, also whole setup has to be robust somehow when the whole network prefix changes.

Sounds like a good use for Multicast DNS?

cool, but "read and change your data on all websites" is imho not worth the functionality. that seems ripe for takeover by some scammer.

Just download the repo as a zip file and manually upload it as an extension to your browser.

Though be warned, after a restart Firefox doesn't re-enable side loaded extensions that were added in the "debug" mode.

Also, Chrome (Google) has a habit of randomly disabling or removing side loaded extensions. I even had a side loaded extension that Google forced removal of because Google deemed it contained malware (which it didn't, I know because I wrote it).

IPv6 is still pretty useless to most people... Actually for me it complicates my firewall rules and don't bring any benefits (yeah down-vote me and don't reply ...)

I don't understand what you mean by complicating firewall rules,except maybe that you now need to use IPv6 addresses instead of IPv4 addresses in some of the rules. It's not like NAT without a firewall gave any security in 2024.

More rules equals more complexity....

I grew up with IPv4 too but after learning and configuring my network for IPv6 I won't miss v4 at all. It's just so nice having each device with its real IP address rather than some private NAT thing. Then it's just firewall config if you want to run servers etc rather than messing with NAT configs.

Doesn't that mean if you move, or if your ISP changes your IP, all your local devices will end up with different addresses? I have an internal DNS server and it would be annoying if it could randomly break and require me to update all the IPs.

I use ULA addresses in my local dns, the global address can change, privacy addresses can cycle and my local DNS keeps working. This also guarantees that the data you are pushing locally stays local since ULAs will never be sent out of the local network.

One of the features of IPv6 is address autoconfiguration, obviating the need for a central authority like DHCP on v4. However, that only works with a /64 prefix and given that larger sites might want to have multiple subnets, that’s why most assignments are /56 or /48. But still. If all assignments were /48s, that would still leave room for 281 trillion networks which even I believe is enough for the foreseeable futu…

I still haven't figured out how to get these auto-configured addresses into my home network's DNS (or any DNS, for that matter).

It is pretty easy on OPNsense but it's virtually impossible on many other types of routers. Meraki and Asus as two examples of that.

To determine ipv4/6, do you need to send that hostname and ip off to somewhere to get a response? or can it be done locally without leaving the machine?

You can determine that by looking at the value. IPv4: 123.123.123.123 IPv6: 2001:db8::8a2e:370:7334

Oh yeah. DUH!

"Pretty useless" is nonsense; Google works on IPv6, and 41% of Google's users access it via IPv6 [1]. "Most people" is also not true: most internet users use Google [2] (those not accessing it via IPv6 probably can't). [1] https://www.google.com/intl/en/ipv6/statistics.html [2] https://www.statista.com/statistics/216573/worldwide-market-...

Because you can access a website on both ipv4 and IPv6 doesn't really make IPv6 all that useful because you could disable it and still be able to access the same resource using ipv4...

By that logic, you can disable IPv4 and still access the site via IPv6.

IPv4 is useless.

Also, running dual-stacked servers I can confirm, all scans come via IPv4, so not only it is useless, it’s actually less secure to use it.
