How can you forget the king of all protocols, RIP? :)

But seriously, I still don't understand the semantics. If you're "routing"
those protocols, you're also routing SMTP, DNS, POP, IMAP, HTTP,
HTTPS...wacky multiplayer game protocols...anything that runs on IP,
basically.

So you're either routing IP, or you're routing `wc -l /etc/services`
number of services plus possibly infinite more.
