(I overlooked your reply; sorry to leave you hanging)

From a simplicity standpoint, Just use InetAddressPoint. Solr has no
rules/restrictions as to which Lucene module it's in.

That said, I *suspect* a Terms PrefixTree aligned to each byte would offer
better query performance, presuming that typical range queries are
byte-to-byte (as they would be for IPs?). The Points API internally makes
the splitting decision, and it's not customizable. It's blind to how people
will realistically query the data; it just wants a balanced tree.
For the same reason, I *suspect* (but have not benchmarked to see) that
DateRangeField has better query performance than DatePointField. That said,
a Points index is probably going to be leaner & faster to index.
