So your network connection should be plenty fast enough to do your own resolving, rather than forwarding queries to your provider's servers. Roughly how much of that bandwidth is available at any given time? If other queries work OK, then the answer is probably, "a sufficient amount". Your reverse zone is handled by your ISP, I see. So your main server needs to resolve your web server's reverse lookup request through the standard recursive routine. This is obviously not working. I noticed some irregularities in the setup of the reverse zone. Specifically, in the delegation and authority records. from f.root-servers.net: 238.63.in-addr.arpa. NS ns1.qwest.net. 238.63.in-addr.arpa. NS ns2.qwest.net. ns1.qwest.net. A 216.111.65.217 ns2.qwest.net. A 205.171.16.250 from ns1.qwest.net: 152.238.63.in-addr.arpa.

A 63.238.152.2 Note the record marked with "**". That may be what's tripping up QuickDNS. Everything before that is perfectly kosher. Pretty much everything after that is screwy and sloppy, but workable. ____________________________________________________________________ Chris Buxton Men & Mice cbuxton@menandmice.com We Make DNS Easy!
