I realize 127.0.0.1 is my computer,

All addresses from 127.0.0.0 to 127.255.255.255 are on your machine.
They are called loopback addresses (because they loop back to you).
Usually the machine grabs the first routable address, 127.0.0.1, and
uses that for itself. Sometimes services will pick one of your
268,435,454 available addresses to use as its own.
In this case it's probably some sort of DNS. (DNS runs on port #53).
Here whatever it is is running on 127.0.0.53 port 53.
I use port numbers in my localhost services all the time.
127.53.0.0 authoritative DNS
127.0.53.0 resolver/caching DNS
127.0.0.80 webserver
You get the idea.
