Re: How To Share DNS On Internet Gateway
to answer the last question first - no. You can distribute IP's without a dns server, but you cannot distribute dns servers alone (at least not via dhcp). If a client has an ip address it will not query for a dhcp unless manually forced to give up it's ip configuration.
As for the dns server in general - there are two ways to do this.
1.) use dnsmasq. This is a small tool which will only forward queries send to the server to it's own dns server. It cannot handle any dns-requests itself. So if you only need the forward, then use this tool.
2.) use bind. Ok, this is a full blown dns server which can do all the usual things... but if you need dns records for your own internal domain, want ddns in cooperation with your dhcp server or want a caching dns server (not sure if dnsmasq does that), you'll need to configure bind...
hope it helps
