hostname
uname -n

Bob had an excellent example:
ip addr | awk '/inet/{print $2}'

Of course this might be local and private addresses, not the IP address 
used for your internet connection.

Most GNU/Linux distributions configure the shell prompt to display the 
usually helpful info, i.e. user name, host name, current working 
directory. Some people use color (or even blinking) to highlight working 
as a privileged user (root).

Most shell configurations provide this info all the time.

You can use 'who', 'w', 'last', 'pinky' or 'finger' to find out from 
where you (and others) are connected (and some additional info as well).

This kind of tracking functionality should be strictly opt-in.

All in all I don't see a need for a 'whereami' utility at all.
