Just to follow up on my posts, there is another blocking message you may be wondering about. [local ip]:5353 -> 224.0.0.[x]:5353 -- this is a mulitcast address and it basically exists so you can be lazy on the network and "discover" printers, "files to look at, and people to talk to." -- according to the arch wiki. If you're a purist, you want this immediately terminated and, if you wanted to actually connect to a device on your network, you would manually type in the correct address of said device. Solution to the problem:
# systemctl disable avahi-daemon $ reboot
After that, no more "discovery" attempts on the network.
