For example: host gmail-smtp-in.l.google.com <http://gmail-smtp-in.l.google.com>[2607:f8b0:4002:c01::1a] said: 550-5.7.1 [2607:fc50:1000:1f00::2 16] Our system has detected that this 550-5.7.1 message does not meet IPv6 sending guidelines...https://support.google.com/mail/answer/81126?hl=en#authenticationMy point was that Google told me it rejected "2607:fc50:1000:1f00::2 16". In this case, 2607:fc50:1000:1f00::2 is the correct address, but it appeared (to me) that Google's data was somehow corrupt. I'm pretty sure the IPv6 address format doesn't allow spaces. ;)
Ah yes, the confusion with the separator between IP and ports. IPv4:port IPv6.port That gets a lot of regex confused...
