> This is a remaining piece of https://issues.apache.org/jira/browse/HTTPCORE-616
> org.apache.hc.core5.net.InetAddressUtils: Parsing may fail when an IPv6 scope id might be provided.
> The following should likely succeed, but currently does not:
> {code:java}
> @Test
> public void testScopedIPv6Address() {
>     Assert.assertTrue(InetAddressUtils.isIPv6Address("fe80::1ff:fe23:4567:890a"));
>     Assert.assertTrue(InetAddressUtils.isIPv6Address("fe80::1ff:fe23:4567:890a%eth2"));
>     Assert.assertTrue(InetAddressUtils.isIPv6Address("fe80::1ff:fe23:4567:890a%3"));
> }
> {code}
> This feature will impact parsing as well as detection, because as I understand it {{fe80::1ff:fe23:4567:890a%eth2"}} is URI encoded as {{https://[fe80::1ff:fe23:4567:890a%25eth2]:443/}} (note the {{%}} is percent-encoded to {{%25}}).
> This is based on a quick look at the ipv6 wiki page, I need to read though the current RFC guidance to verify the data I've provided is accurate.
