AS A user with only IPv6 connectivity
I WANT to be able to use MusicBrainz just as well as a user who only has IPv4 connectivity

Worth having a think about what would be needed to make this happen.

DNS

• Do our DNS zones support AAAA records?
  • 
• Are our NS's reachable by IPv6?
  • everydns isn't
  • ns1.digitalwest.net isn't
  • ns2.digitalwest.net is
• Are all the other dependent DNS servers reachable by IPv6?
  • 
• Also check CNAMEs pointing to external domains: their NSs, their dependent NSs, the name itself, ...
  • 

Hosting

• DW servers (or at least, user endpoints) need IPv6 addresses
  • todo
• Non-DW user endpoints (OSL@OSU, hefty, ...?) need IPv6 addresses
  • ftp.musicbrainz.org => musicbrainz.osuosl.org => ftp.osuosl.org => no AAAA
  • rsync.musicbrainz.org => rsync.osuosl.org => no AAAA

Infrastructure

• carl/lenny nginx. Does it "just work"?
• carl/lenny incoming connections SMTP (etc)
• Does webalizer support IPv6?

Software

• Is mb_server limited to IPv4 only?
• How would mb_server per-IP rate limiting work?
• Client apps (Picard etc), as long as they use IPv4/6-agnostic code, it should hopefully "just work".
