What’s exactly my router querying on these addresses?


I’m trying to understand how my router works so I’m analyzing a couple of outputs (I logged in through SSH). I get these lines when trying netstat -a -e, and I’m not sure where do these addresses come from, or what they are exactly doing.

The xxx.xxx.xxx.xxx is the IP address that my router gets from the ISP router (WAN).
