I have been using queries like these to test: dig any . @f.root-servers.net | egrep "(DiG 9|AAAA)" dig +bufsize=1400 any . @f.root-servers.net | egrep "(DiG 9|AAAA)" The first offers up a standard DNS query, the second an EDNS0 query of 1400 bytes.

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 (?). With EDNS0 the packet size increases to 615 bytes and they all serve up all glue records since about 30 minutes ago.

:-) I was expecting trouble because of truncated responses that need a retry over TCP, but that doesn't happen, at least not with the dig tool. So apparently firewalls aren't going to cause trouble after all. And the new named.root has arrived: ftp://rs.internic.net/domain/named.root

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/

I seem to think it has become fairly widespread practice for people to refresh their named.root files (or whatever they decide to call it) using something like this: $ dig . NS >named.root This worked before today. From today, it still works (in the sense that it will still result in a named.root file which is sufficiently complete in most situations for a nameserver to be able to send a priming query) but it won't contain a complete set of glue. So, if you're in the habit of doing dig . NS >named.root you would ideally change that habit to something like curl -O ftp://rs.internic.net/domain/named.root instead.

If you're willing to use an EDNS0 query, this works: dig +bufsize=1400 . NS > named.root I'm not sure if that's better or worse. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

Why? dig is quite capable of coping. Depending apon dig's age and firewall configuration one or more of these will work. dig +edns=0 . NS @a.root-servers.net > named.root dig +bufsize=1200 . NS @a.root-servers.net > named.root dig +vc . NS @a.root-servers.net > named.root As none of these sets DO, they should suffice for the foreseeable future. When DNSSEC is deployed for the root and root-servers.net you will want to do crypto checks. Even then the above queries won't break. Mark

In a standard query you're only going to get 3 AAAA records, EDNS0 should allow for all of them. There are currently 6 servers with AAAA records:

There is an interesting variation in what records are returned for a standard 512 byte request (dig ns . @[x].root-servers.net): A,C,D,E,F,G,I,J: return the same 10 A records and 4 AAAA records in the same order every time. They never return A records for K,L,M and never get AAAA records for K,M. B: returns all 13 A records in random order and then two AAAA records in random order. This allows all records to be returned with equal weight within each record type. H,K,L,M: return all 13 A records in static order and then A and F AAAA records so H,J,K,M AAAA records are never returned. Tested with dig 9.4.1-p1 on a v6 enabled system. - Kevin

I concur. An interesting thing I noticed that doesn't really cause an operational problem but may confuse some people is their behavior is also quite different when queried for "any". If your a lazy admin like me who is used to typing "dig any foo" for testing you may try "dig any . @[a-m].root-servers.net." When I do that, I get the following response: a, c, d e, f, g, i and j return 1 SOA, 8 A, and 3 AAAA's (the first 3). b, h, l, k, and m return 1 SOA, 13 A, no AAAA records. If you make this mistake you might think b, h, l, k and m have no IPv6 data, which is wrong. Querying with NS (as nameserver would do) clearly shows that. While a cosmetic problem, I fear it may confuse a number of admins as the troubleshoot problems in the near future. -- Leo Bicknell - bicknell@ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/

How does a cache-resolver know that it's time to issue a query with edns0?
cache-resolver that support EDNS0 will make EDNS0 queries by default. They will fallback to plain DNS if the query fails or they get a response that indicated the authoritative server doesn't support EDNS. BIND's been making EDNS0 queries for ~8 years now. If your cache-resolver doesn't support EDNS it is long past time to upgrade. Mark

It won't be a issue. IPv6 capable nameservers are supposed to use EDNS (see IPv6 node requirements). The roots can be tuned to preference A vs AAAA records.

So would there be benefit in the roots being tuned to only return AAAA if the request is EDNS? Just out of curiousity that is.
