hosts problem.

[Tommy Moore]

Hi guys. Have a little problem here that you might be able to help me
with.
I have a network here that's on the internal block 172.20.0.0/16. On the
linux server I'm running a pop3 server. The hosts on the internal network
aren't using dns and because of this when client connect to the box they
hand.
The ip addresses for the clients are handled dynamically and in
/etc/hosts.allow I have:
all: 172.20.*.*
Will this allow the clients to connect or how do I make it so that the dns
doesn't time out since I suspect this is what is happening.

Thanks.

Tommy
