How to know what user belongs to what ip on debian

Question

is there a way to get an overview of users logged in on my server and the ip they are connecting from ?

I have the IP already, I want the user that is associated with it :)

I think @jscott used a sly comment to pad his answer out.

Use the who command. It lists everyone logged in, their terminal and their source hostname/ip address.

In addition to w¹ and who², you may also look at finger³.
