Public bug reported: I access the following URL, which is done via IPv6 and returns my IPv6 address:
https://craig.mcqueen.id.au/ip.php Then I access: https://ipv4.craig.mcqueen.id.au/ip.php That sub-domain has only a DNS A record, which should force it to be an IPv4 access. But, somehow Firefox manages to access it via IPv6 and return my IPv6 address again. I think Firefox should access the second URL via IPv4.
