I realize 127.0.0.1 is my computer, but I'm not clear on how 127.0.053 and 127.0.0.53#53 are used.
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.
