Review comment:
since this will be checked every row, should we maybe store both
`IPAddressString` and `IPv4Address` so we can do whichever `contains` check is
more efficient? (assuming we split long and string handling to not both convert
to `IPv4Address`).

Review comment:
should this parse to an `IPAddressString` instead of an `IPv4Address` so
it can be checked against the `subnetString` directly?
