(especially if named-checkzone would fail to OK a zone with NSEC3RSASHA1 keys and re-used NSEC records :) NSEC3RSASHA1 w/ NSEC is fine and is required if you want to transition from RSASHA1 (w/ NSEC) to NSEC3RSASHA1 w/ NSEC3 w/o going insecure. NSEC + NSEC3PARAM however could be rejected as could having multiple NSEC3PARAM records. Paul Not named-checkzone (yet) but the following are in BIND 9.6.2. 2686. [bug] dnssec-signzone should clean the old NSEC chain when signing with NSEC3 and vice versa. [RT #20301] 2683. [bug] dnssec-signzone should clean out old NSEC3 chains when the NSEC3 parameters used to sign the zone change. [RT #20246] dnssec-signzone works on the zone as a whole so it is in the position to do this in a straight forward manner. Named, however, needs to support multiple NSEC3 chains (though not all may be complete) as it does its work incrementally but perhaps it could be argued that when you finish adding new NSEC3 chain incrementally the old one should be removed.

Dig ANY gives SERVFAIL / FORMERR
Hi, I operate a caching naming server version 9.5.0-P1 for a small work group that includes an email server. From the server log file, there are occasional DNS error messages. Upon closer examination using a packet sniffer, the email server sends out queries of type ANY for all sender/recipient domain names. There are just some domains which cause errors, for example, youbei.cc (which is not under our control.) I tried dig any youbei.cc and it returns the following error: ;; -HEADER- opcode: QUERY, status: SERVFAIL, id: 64259 ;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0 With heavy tracing turned on and rndc flush before executing the command, it gave the following log entries that I excerpted below: 24-Sep-2009 02:07:35.878 received packet: ;; -HEADER- opcode: QUERY, status: NOERROR, id: 28529 ;; flags: qr aa ; QUESTION: 1, ANSWER: 5, AUTHORITY: 0, ADDITIONAL: 3 ;; QUESTION SECTION: ;youbei.cc.

I think 72dns.com has a broken DNS server. More modern versions of dig will also report the mismatch. The servers also answers queries with A records. It's a pity registries are not required to verify correct operation of the nameservers they are delegating to before accepting the delegation. If they were then a lot of this garbage would cease. It really isn't hard for a registry (or the registrar on behalf of the registry) to check that servers answer queries correctly. Just the almighty dollar has got in front of having a working system.
