Description
Hi,
If I'm not mistaken, brackets are optional for an ipv6 address without port number. The problem is that it confuses django. In asgi.py we have
`
Invalid HTTP_HOST header: '2001:x:y:z:0:0:0:1'. The domain name provided is not valid according to RFC 1034/1035.
`
which can be fixed by changing django.http.request.host_validation_re to _lazy_re_compile(r"[a-zA-z0-9.:]*")
but it also triggers an exception with asgi.py
`
