For example: I question whether we really need as many secondary name servers as are currently being used. We currently have 9, which is 3 more than I have for a anti-spam DNSWL that I run. How many DNS lookups/day are being made to pool.ntp.org right now? Cutting back to, say, 3 or maybe 4 name servers would significantly cut down on the packet size. The NS records tend to be much larger than A records because they have a domain, instead of a 4 byte IP address, and for each NS record, the software tries to add an A record. Also, the 2 minute TTL for the A records is probably too short. I don't see much reason to make them shorter than the zone regeneration time, and the could be somewhat longer. -wayne _______________________________________________ timekeepers mailing list [email protected] https://fortytwo.ch/mailman/cgi-bin/listinfo/timekeepers
