Subject "isIPv6Address" api in InetAddressUtils.java (httpcomponets-core)
Date Sat, 01 Jul 2017 18:56:45 GMT
Hello Everyone,

As per RFC 4291 (https://tools.ietf.org/html/rfc4291#section-2.2) , IPV6 address can be represented
in 3 ways:a. 2001:DB8:0:0:8:800:200C:417Ab. ::1 c. ::  
"isIPv6Address" within InetAddressUtils checks only for a, b (above) and does not consider
IPv4MappedIPv64Address (case c) as valid.  
Based on the RFC, option c above is considered valid. Does anyone know why it is not considered
as part of api "isIPv6Address" api above ? and alternatively should it be considered as valid
reference: https://github.com/apache/httpcomponents-core/blob/master/httpcore5/src/main/java/org/apache/hc/core5/net/InetAddressUtils.javahttps://tools.ietf.org/html/rfc5156#section-2.2 
 --  ::FFFF:0:0/96 are the IPv4-mapped addresses [RFC4291]. Addresses
   within this block should not appear on the public Internet. 
commit where isIPv4MappedIPv64Address was added but does not look like it is being used.  Does
anyone know any particular usage of IPv4MappedIPv6 ?https://svn.apache.org/viewvc/httpcomponents/httpcore/trunk/httpcore5/src/main/java/org/apache/hc/core5/net/InetAddressUtils.java?r1=1406216&r2=1444926&pathrev=1767956&diff_format=h
