Guess here, but I suspect you've got it configured as a recursive DNS server, and it's acting as a full DNS server. (As opposed to a stub resolver which isn't able to make recursive queries.) In short, it asks the root name servers for information and down the line, till it gets the actual host information you were asking for, and then returns it to the requesting client or app. Cheers, Greg > I added some information to my named configuration so sendmail could > resolve the reverse look up of the private LAN addresses.... or at least > get an error quickly instead of timing out > In order for this to work, I manually changed /etc/resolv.conf , > deleting the exisiting nameserver statements, and adding nameserver > 127.0.0.1 > Works great....
