Hi All,  
I am trying to index the document with field having value as IPV6 mapped IPV4 address in the field with type as ip\_range.  
However ES throws following error:  
CIDR notation is not allowed with IPv6-mapped IPv4 address [::ffff:10.170.0.0/112 as it introduces ambiguity as to whether the prefix length should be interpreted as a v4 prefix length or a v6 prefix length.  
Could anybody please help with workaround to store this kind of address in field of type ip\_range?
