Is anyone else having issues reaching GMail on IPv6 via IMAP, or is it just me? Here's some of what I'm seeing: It responds to ping... imac01:~ branto$ ping6 imap.gmail.com PING6(56=40+8+8 bytes) 2001:470:8d30:b00c::bb0e --> 2607:f8b0:400d:c00::6c 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=0 hlim=55 time=31.299 ms 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=1 hlim=55 time=41.528 ms 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=2 hlim=55 time=30.092 ms 16 bytes from 2607:f8b0:400d:c00::6c, icmp_seq=3 hlim=55 time=35.450 ms ^C --- gmail-imap.l.google.com ping6 statistics --- 4 packets transmitted, 4 packets received, 0.0% packet loss round-trip min/avg/max/std-dev = 30.092/34.592/41.528/4.470 ms TCP Sessions on v6 seem to time-out: imac01:~ branto$ telnet -6 imap.gmail.com 993 Trying 2607:f8b0:400d:c01::6c... telnet: connect to address 2607:f8b0:400d:c01::6c: Operation timed out telnet: Unable to connect to remote host IPv4 Connects: imac01:~ branto$ telnet -4 imap.gmail.com 993 Trying 173.194.76.108...
