Maybe it's just me, but isn't there something odd about a DNS query coming back with 78 entries for the same host? It sends back an UDP packet that gets truncated and the DNS resolver reverts to TCP to get the full list.
It is not necessarily odd. Network management applications such as OpenView work best if the DNS lookup for a router returns all the addresses configured on the router. The UDP packet can overflow and be truncated with 22 entries.
It seems to cause problems with Windows clients and/or Windows DNS servers. Seems like overkill.
I feel your pain because I use a DNS module in my scripts that craps out when it sees one of these truncated packets, but then the problem is with the client and not DNS. It is too bad that the DNS packet size can't be increased to 1500B. David Russell ThruPoint, Inc
