Actually I get (almost?) always 10 As and 4 AAAAs from A and J running "VGRS4", C, D, E and F running BIND 9.3.2-P1 - 9.4.2 and G and I running unknown software. H, K and L run different versions of NSD and give me the 13 As and two AAAAs, as do B running BIND 8.4.1-REL and M running BIND 9.4.2 (?).
I'll go back to the part where I'm not a DNS expert. :) I get 8 A's + 3 AAAA's in my attempts at a regular query. Seems to be the same across all servers that return AAAA's. I'm using dig 9.5.0b2 for what it's worth.
With EDNS0 the packet size increases to 615 bytes and they all serve up all glue records since about 30 minutes ago.
Actually, just to be sure I set my EDNS0 packet size to 1400. However, I agree with your assessment, using EDNS0 I get 100% of the answers from all 13 servers over IPv4, and from all 6 IPv6 capable servers over IPv6. There are still a number of servers returning zero AAAA's when queried with a regular query over both IPv4 and IPv6. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/
