DNS Timeout Question

[Osmosis]

What is the timeout for Efnet servers in regards to forward and reverse? I notice my ip address doesn't resolve on any server except irc.nac.net.

It might be because of the recursiveness of my reverse DNS servers. ip-in-addr -> ip-in-addr.datacenter.reverse.server.com -> ip-in-addr.my.reverse.server.com

Ratbox does not allow more than one CNAME in a reverse lookup. One CNAME is allowed because that is the way to delegate reverse DNS for smaller than a /24. Any more than that would make the ircd spend too much time chasing CNAMEs imho.
