DNS for local zone

[karstens]

What do I have to do if I just want to set up an DNS-Server for my local network without any official IP Adress. It is often described how to configure the files with
adresses which exist in the Internet, but what if I have no official adress ?
I use Redhat 7.2 with bind8.

If you don't have "official" addresses I'd assume that means you are on a lan that would probably use 10.0.0.* range or 192.168.0.* or something like that. Just set up the DSN using your local network addresses.

Yes, but what if I want to reach both, internal and external. And does it matter if I use a domain-name which already exists in the internet ?

You'll need to find some type of machine (firewall or router) to NAT (network address translation) your internal addresses. Look up info on NAT'ing and it should give you the information you need, your internal nodes will stay hidden, although you will need to advertise at least one external IP. Hope this helps.
