RDNS Queries

Hey everyone,

I have a question, I've been playing around with tcpdump, and noticed my machine making numerous rdns look ups. They are displayed like:

Code:
10.80.80.141.51234 > 10.80.80.1.domain: 9950+ PTR? 223.114.55.65.in-addr.arpa. (44)

My question is, if dns works based on numerical addresses... why does my machine care what the domain name of a site is..? And where are these requests coming from? I'm obviously not the one typing the addresses into my browser?
