Double DNS server

I have a domain pointing to my server.
Is it possible to configure the dns server so that it gives two different answeres acording to the requesting ip?
I need that it gives IP like 192.168.1.23 to the computer in my network, but ip like 236.48.215.32 to the computers outside the network.

Re: Double DNS server

Use /etc/hosts for your LAN.

If I use /etc/hosts I don't have to configure it on every machine? Or only on the server?

Re: Double DNS server

the easiest solution is probably going to be split dns.

You can use /etc/hosts on server, install dnsmasq and tell all local clients to use that dnsmasq server.

Re: Double DNS server

If the clients are windows PCs, you can put the server into C:/windows/system32/drivers/hosts

This file is consulted before any DNS lookup, so putting your domain and then the 192.168.*.* address should override anything in DNS.

The DNSMASQ solution would also work, but you would be required to have your server on for your clients to access the internet with any sort of speed (or such is my experience), because the windows clients try to connect to the DNS server each time they want to do a lookup, and you have to wait for the connection to the server that isn't there to time out before a new server is tried.

Thanks to all. Now everthing works.
