I wouldn't say it's the exact same problem, because at least the address gives you something to go on (you can verify whatever data against the hash to make sure it's correct and unaltered). But the problem of resolving hashes is something every content addressing system must deal with. The most common answer is distributed hash tables. Personally, I'm fond of local resolution. One of the coolest things about content addressing is that you (or anyone) can choose how to resolve addresses, so an ecosystem is possible (sort of like the Wayback Machine today, or the coexistence of various search engines).
