Most likely, especially if the IP address is not the first column in
your primary key index.
Have you done an explain analyze of your ip lookup query? If not, do
so; that can help. Then try creating the index and explain analyze the
query again to see what happens.
Knowing your existing schema/indices and such would let us do more
than guess- and not knowing the plan your current query is using makes
it difficult to know if there's a better one using a to-be-created
index.
