[New-bugs-announce] [issue34453] ipaddress module accepts some strange IPv6 addresses that it shouldn't

[Luke Kenneth Casson Leighton]

New submission from Luke Kenneth Casson Leighton <lkcl at lkcl.net>:

adding some unit tests to some code being written,
searched randomly on the internet for an IPv6 test
suite and found one in php *shudder*
# https://github.com/gws/ipv6-address-test/blob/master/Tests/Ipv6TestCase.php

converted it to python, and was surprised to find that
there are two cases which the ipaddress.IPv6Address
module accepts, that it should not!

attached is a quick-and-dirty hacked together unit test
which shows the issue.  the full suite may be found
here (over 400 ipv6 addresses to test):
