Hi Folks, I've just encountered this issue, and it seems Django's URLValidator regex for host is trying to abide to RFC 1034 recommendation <https://tools.ietf.org/html/rfc1034#section-3.5> , when there are many sites in the wild that use underscore in their domain name.
Can we please discuss this issue here, so we can eventually decide to reopen the ticket (or not) and perhaps allow for a pull-request to fix it? I found this stackoverflow question helpful, with many answers/comments with additional references: https://stackoverflow.com/questions/2180465/can-domain-name-subdomains-have-an-underscore-in-it Best regards, Pavel -- You received this message because you are subscribed to the Google Groups "Django developers (Contributions to Django itself)" group.
