That Microsoft lecture at UKNOF that I linked to some while back showed just how much kit does IPv6 and yet still has some stupid dependency on something IPv4, and the devs never spotted this (er because they don’t do code reviews!!!) because they didn’t test in an IPv6-only environment. (I have an IPv6-only Raspberry Pi hosted by Mythic Beasts. Specifically meant for shaking such bugs out.)
@craigski - thank you mDNS it is; I see Microsoft is using it now too, instead of LLMNR. Yay, sanity!
@XGS_Is_on I too do nothing, but it’s because of the annoying random privacy addresses that Apple always use that I would like to use either link-local name resolution over mDNS, or better something like that linked to real DNS so it’s globally visible. I would really like to be able to just IPv6-ping some named box on my LAN to see if it’s alive, and currently I can do that with IPv4, and even do so from
outside the LAN as I have a firewall hole (by src IPv4 addr) for my own iPad, so if I’m in hospital I can still reach in and see what’s up with the various boxes in the network.
I wonder if I can sweet-talk RevK into implementing mDNS support and mDNS-to-DNS conversion? This so that single-label domain names could be published in the DNS and resolved on the LAN by mDNS, and also FQDNs such as "<mdns-host>.lan.weaver.com" could be published likewise based on the defined DNS suffix "lan.weaver.com".
My point about the ease of memorising addresses is that IPv6 addresses that you do remember very often are not any longer than IPv4 ones. I have 10 hex characters in my /48 prefix.
The process of giving out /32s to ISPs and similar users somehow irrationally worries me, even though I know that we’re never going to have more than 2
32 ISPs, we’re back to allocating out of 2
32 again. Mind you, you could make some smaller ISPs keep all their customers in a /40 say and each end-user only gets a single /64, no more. I can’t understand the logic of giving out /48s to true ‘home’ users; /56 will be more than enough and a /60 should be fine for real ‘home’ users, with SOHO users perhaps being treated more generously, but even then, I’m not convinced.
