Actually,  your PostgreSQL server is running on the IP address that is assigned to that computer.

The 127.0.0.1 in the pg_hba.conf file is the initial accepted client IP address that your
postgresql server will accepted connections from.  127.0.0.1 is basically means localhost.  So,
your pg_hba.conf file is initial configured to only allow client connections from itself.

So in this case, if you want to connect from an IP address from a different computer, you will
need to specify that ip address in your pg_hba.conf file as well as the permissions.

But just to get started, you could try editing a line in your pg_hba.conf to this:

#host    all     all         127.0.0.1/32                md5
 
host    all     all    <your client ip address goes here>/24         trust
host    all     all         127.0.0.1/32                trust

To understand all of this, you will need to read the introduction in your pg_hba.conf file. Also,
keep in mind that the above change is basically an "open door" to everything in your DB server. 
So after you've had a change to get familiar with everything, you will want to tighten up on
how,what, and how access is granted to you system.

"Last but not least", you will need to restart your postgresql service so these changes will take
effect.

This should get you connected.
