The ipv4 column is of type inet. It is the primary key (btree access) and access times for queries on individual ip addresses have been around 10-15 ms.

There are 127k lines like that (each with a different range and the appropriate country code). Each is terminated with a semi-colon. Does that make them individual transactions in postgres or not? (postgres newbie here). Is there something else I need to do for them to be treated like separate transactions?
If you did not wrap the whole thing with begin/commit then each is its own transaction. I certainly hope you have an appopriate index on that ipv4 column and it is appropriately typed.
