Q.  What is IP-address ?

A.  That's the IPv4 address of "localhost" -- or "this computer".

On any nearly any computer (Windows, Mac, Linux) you should be able to
use the "ping" command:

ping localhost
And get a reply such as:
PING localhost.localdomain ( 56(84) bytes of data. 64 bytes from localhost.localdomain ( icmp_req=1 ttl=64 time=0.090 ms 64 bytes from localhost.localdomain ( icmp_req=2 ttl=64 time=0.121 ms 64 bytes from localhost.localdomain ( icmp_req=3 ttl=64 time=0.123 ms
This means your computer is able to communicate with itself (which is good). There are some TV shirts that say "There's no place like" meaning, of course, "there's no place like home".
