find ip address using hostname

I have two linux servers and i'm trying to access them remotely. I know the ip of the first server but i forgot the ip of the other one.

I'm trying to use nslookup, I did

nslookup server2

and the output was:

Server: 192.168.2.1
Address: 192.168.2.1#53
Non-authoritative answer:
Name: server2
Address: 90.222.143.15

and then i tried to use it again but with server1 and I got the same output...

Anyway, why is the output the same for both server? is nslookup the better option to find out the ip of the other linux server that i have? What other option can I use?

Try using ping instead:

$ ping server2

nslookup and ping use different techniques for name resolution.
