HTTPS over IPv6 · not part of the grade yet
Redirects to synclo.com.au, which has no IPv6 address — so IPv6 visitors end up needing IPv4 after all.

What's keeping getsynclo.com from an A

  1. A redirect leads off IPv6
    Redirects to synclo.com.au, which has no IPv6 address — so IPv6 visitors end up needing IPv4 after all. Give the redirect target IPv6 too, or redirect somewhere that has it.
  2. Mail servers without IPv6
    mx.zoho.com.au, mx2.zoho.com.au, mx3.zoho.com.au have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
