I haven't looked at the DNS cache code, but unless you're also caching
and handling the records' TTL, blindly caching DNS records within the
app is a dark road to go down.  Some apps (namely browsers) do it
anyway, but get away with it by setting their internal TTL
significantly lower than that of a typical record.

What kind of performance hit are you actually seeing with DNS lookups?
