I wake up and see the HackerNews downvote train has hit myself and you, when what you said is 100% correct; gmail-smtp-in.l.google.com is both IPv4 and IPv6.
The network I'm on right now (VPN to work) cannot service IPv6 and I cannot connect to the IPv6 IP for that MX host, but I can easily connect to the IPv4 endpoint.
