Those two are
squid.cacheNetwork.cacheIpCache.cacheIpHits
and
squid.cacheNetwork.cacheIpCache.cacheIpMisses

What you are looking for are
squid.cachePerf.cacheProtoStats.cacheProtoAggregateStats.cacheHttpHits
.1.3.6.1.4.1.3495.1.3.2.1.2
and
squid.cachePerf.cacheProtoStats.cacheProtoAggregateStats.cacheProtoClientHttpRequests
.1.3.6.1.4.1.3495.1.3.2.1.1

there is no SNMP variable for the number of misses, but you can
calculate it by substracting the hits from reqeusts.

It should. You are looking into the IP cache where Squid internally
caches DNS lookups.
