They absolutely can and some do. The destination UDP port number of a UDP packet traversing the core network of an ISP can be inspected and acted upon as one pleases.

Unless it is tunneled over an binary obfuscation layer, and wrapped in a purposely weakened cryptography to booby-trap their parser.

There is also the global satellite uplinks... so its ultimately a pointless game to keep people ignorant, that is unless they plan to follow people around like a hot-air balloon villain from Pokemon Go. lol =3

my point is you can point a call to 53 on a machine on your own network and you isp cant do shit about that

Very well. You have pointed your DNS resolver to a host on your local network for the DNS name resolution.

When a DNS lookup request hits it, where does a UDP packet on 53 goes out to and what happens to it?
