Finding the NODE NAME or IP

I am working in a Linux network, with more than 50 nodes.
From my node I login to various machines/nodes for the conveniences of
access.

Now my question is; I have logged in to another system in the network from
my machine/node. Once I am logged in to another system, how can I know the
name of my system (or my IP address)

I am aware that by typing in "w $USER" I can get the log, but, what should
I do to get just my node name or IP address; and nothing else.

I am requesting this so that this could be used in shell scripting, to
identify the local node.

Thanks,
Lince M Lawrence

The name can be returned with the hostname command. The IP is obtainable using
ifconfig.

I think he meant the name of his "local" system, where the login
came from.

Lince:
As "w" prints out this information just "sed"ate it.

Maybe better way, esp. if there are more logins from one user:
SSH declares two variables:

SSH_CLIENT="192.168.1.232 2016 22"
SSH_CONNECTION="192.168.1.232 2016 192.168.1.230 22"

This is a login from my local box 192.168.1.232 to my mailserver
192.168.1.230.
