Imagine this scenario.

I've setup a DNS server for my LAN at ip 192.168.0.2/28. The zone name for this subnet is "com". I have 2 clients connected to this server named "google" at 192.168.0.3 and "yahoo" at 192.168.0.4. I know that from either/both of these 2 clients, I will not be able to get to the actual google.com and yahoo.com. What other methods can I use to get to the external internet?

That's because the google.com is found directly in your local network and is known by your DNS server with the ip addresses 192.168.0.3 and 192.168.0.4.

That doesn't surprise.

Right, I understand that having google.com in LAN DNS will resolve locally. My question was how to get to the external internet from either of these clients?

Perhaps if you explain what it is you're trying to do we could help you.

What you have done is in no way going to help you get to google and yahoo from a LAN.

If you have external connectivity, you could just type "www.google.com" or "www.yahoo.com" in the URL field of your web browser and voila, you're there.

The goal is to get to any public website from either of my LAN clients that have domain names google.com and yahoo.com. If I am on my client named yahoo.com, and typed in www.yahoo.com in the web browser, will I actually get to yahoo or will my pc be talking essentially to itself? I guess entering the public IP address of www.yahoo.com in the browser may be the only way to get to www.yahoo.com from my LAN client named yahoo.com

Right, or you configure your client to use an external DNS server.

Ok I'm a little confused. You said, "The goal is to get to any public website from either of my LAN clients that have domain names google.com and yahoo.com."

Please explain to me why you would want to use domain names already in public use on your internal domains?

You'll excuse me for pointing out that this makes absolutely no sense and, should the people who own the aforementioned domain names get wind of it, they could sue you and have you legally blocked from using it even internally.

As long as the names like google.com are used locally, I guess there is no problem, but I'm with you.
Why would one use domain names, obviously use in the public internet, in the local network?

This doesn't make any sense.
