Caching must be done on at least host names, or virtual servers will
break painfully.

Only cenario I can find where caching on the server IP is useful is a
transparent proxy which does not perform DNS lookups it self. Then
objects must be cached using at least destination "IP, Host header, URL
path" as cache key.

Squid always resolves the server IP itself, and disregards what IP the
client has found when running as a transparent proxy. Therefore I see no
use of including the server IP in the cache key.
