-------------------------------------------------
Draft PR with additional test cases which exhibit the problem. Actually the
test case mentioned earlier passes with the patch now, but there are others
that fail.

> Allow configurable v4/v6 address matching behavior for SAI indexes on CQL
> inet columns
> --------------------------------------------------------------------------------------
>
> Key: CASSANDRA-19492
> URL: https://issues.apache.org/jira/browse/CASSANDRA-19492
> Project: Apache Cassandra
> Issue Type: Improvement
> Components: Feature/SAI
> Reporter: Caleb Rackliffe
> Assignee: Ekaterina Dimitrova
> Priority: Normal
> Fix For: 5.0.x, 5.x
>
>
> The {{inet}} type in CQL allows ipv4 and ipv6 address formats to mix in the
> same column, and while there is a standard conversion between v4 and v6,
> equivalent addresses are not considered equal by Cassandra, when it comes to
> their usage in keys or in filtering queries. However, in SAI queries,
> equivalent v4 and v6 addresses ARE considered equal. Even if this behavior is
> useful, it might be a good idea to make the default behavior consistent with
> filtering, and allow the index configuration to control whether or not to
> consider them equal. (We have precedent for this w/ case-insensitive indexing
> of text columns, etc.)
