Seems to be okay now. I guess the bug can be closed.

Title:
  security.ubuntu.com not accessible in IPv6 (AAAA record missing in the
  DNS)

Status in The ubuntu.com website project:
  Fix Released
Status in update-manager package in Ubuntu:
  Invalid

Bug description:
  Dear,

  The apt source list for security update is by default configured  to
  security.ubuntu.com.

  When you have a system using only IPv6 (and having not access to IPv4 via NAT-PT),
  security.ubuntu.com is only reachable in IPv4. 

  It would be wise to configure an AAAA record to security.ubuntu.com to at least
  point to one of the many mirrors supporting IPv6 connectivity.

  That would avoid system running natively in IPv6 to lack by default the security
  update.

  Thanks a lot,

  Kind regards

  PS : I checked this as being a security vulnerability but this is more a configuration issue
  on the Ubuntu network infrastructure than a real security vulnerability:
   

  A DNS AAAA request :

  
  dig -t AAAA security.ubuntu.com

  ; <<>> DiG 9.4.1-P1 <<>> -t AAAA security.ubuntu.com
