What's the next hop for a cryptographic hash? With IP addresses, you have a heirarchy: You match on a prefix to find the router to handle the next path, and that one matches on a longer prefix to find the next hop, and so on. That allows you to have routing tables that don't include every single host on the internet. This is what allows efficient routing to happen.
