Probably your ISP, given the packet sequence you saw. Unless someone else
can replicate the problem with that IP address. I might try tomorrow, but
openssl's s_client doesn't take ipv6 addresses as arguments, so testing is
more involved.
You mean my ISP does not handle IPv6 correctly, right?
For the short term, is there any harm to stick to IPv4?
