IPv6 production use

My news server (news.w21.org) with a few mostly regional hierarchies has IPv6 connectivity, of course :-). Of my NNTP peers, at least eight are reachable over IPv6. So I can say that I use IPv6 not only for play, but in real production. (Of course, Usenet news is mostly for play. But I digress. :-)

No reverse DNS with ligado

Update: ligado's technical support confirmed that they do not offer customer-provided DNS reverse lookup for the fixed IPv4 address at all (only a generic standard name), so I'll cancel the account.
