Adrien Grand created LUCENE-7920:
------------------------------------
Summary: Make it easier to create ip prefix queries
Key: LUCENE-7920
URL: https://issues.apache.org/jira/browse/LUCENE-7920
Project: Lucene - Core
Issue Type: Bug
Reporter: Adrien Grand
Priority: Minor
Advertising
{{InetAddress.getByAddress}} automatically transforms ipv6-mapped ipv4
addresses to ipv4 addresses. While this is usually desirable, it can make ip
prefix query a bit trappy. For instance the following code:
{code}
InetAddressPoint.newPrefixQuery("a", InetAddress.getByName("::ffff:0:0"), 96);
{code}
throws an IAE complaining that the prefix length is invalid: {{illegal
prefixLength '96'. Must be 0-32 for IPv4 ranges, 0-128 for IPv6 ranges}}.
