ADD a none domain server IP into my DNS server

Hello,

since few days, we have interconnected two clients together throuth SDSL MPLS line (like VPN) so that each client can ping the server IP from each other.

For ex : client A (192.168.50.50) can ping client B (192.168.100.100). That work fine

Now I'd like to add in each DNS server the right settings in order to ping the server name instead of the IP.

As I'm not very good with DNS, I prefere ask before changing settings in it

So xould someone explain me what to do in order to do this?

Thanks in advance

Best Regards

Thierry
