F
IPv6 readiness
The www address publishes IPv6 but doesn't answer on it — worse than having none.
Website over IPv6
tree21services.org has an AAAA record and answers on it.

yes
www over IPv6
www.tree21services.org has an AAAA record, but nothing answered on ports 443 or 80. IPv6 visitors wait for a timeout before falling back to IPv4.
✗ 2a07:7800::138 no answer
broken
Mail servers (MX) have IPv6
None of the mail servers has an AAAA record.
mx.stackmail.com ✗
no
Nameservers have IPv6
No nameserver has an AAAA record — an IPv6-only resolver can't reach this domain's DNS.

What's keeping tree21services.org from an A

  1. Fix or remove the AAAA record for www.tree21services.org
    Something published an IPv6 address but nothing answers on it, so IPv6 visitors wait for a timeout first. Either make the server listen on IPv6 (and allow ports 443/80 through its firewall), or delete the AAAA record until it does.
  2. Mail servers without IPv6
    mx.stackmail.com has no AAAA record, so mail from IPv6-only servers can't reach it directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
  3. Nameservers without IPv6
    ns1.webbhost.co.uk, ns2.webbhost.co.uk, ns3.webbhost.co.uk, ns4.webbhost.co.uk all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
