             Summary: Make it easier to create ip prefix queries
                 Key: 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:

InetAddressPoint.newPrefixQuery("a", InetAddress.getByName("::ffff:0:0"), 96);

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}}.
