             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


{{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}}.
