How can i go about determining what public key from the authorized_keys file
was used by what ip address?

I want to have an idea who is logged on based by the public key comment and
connecting ip.

Look into your log file, locate something like

 Found matching RSA key: a8:36:bc:....

use

 ssh-keygen -lf public-key-file

to find fingerprints of every public key in your authorized_key and
compare them with the fingerprint in the log file.
