Mail servers (MX) have IPv6
No MX records, so mail goes to the domain's own address (implicit MX). It has an AAAA record.		yes
Nameservers have IPv6
No nameserver has an AAAA record — an IPv6-only resolver can't reach this domain's DNS.

What's keeping sistersservicesequipment.com from an A

  1. One of sistersservicesequipment.com's IPv6 addresses doesn't answer
    2600:1f1c:6db:8800:3874:4c01:cb9:391f, 2600:1f1c:6db:8800:79cb:1ef5:7739:e6be, 2600:1f1c:6db:8801:b190:5302:8b46:f792 didn't accept a connection on 443 or 80 while others did. Remove them from DNS or fix that server — browsers that pick one wait for a timeout.
  2. One of www.sistersservicesequipment.com's IPv6 addresses doesn't answer
    2600:1f1c:6db:8800:3874:4c01:cb9:391f, 2600:1f1c:6db:8800:79cb:1ef5:7739:e6be, 2600:1f1c:6db:8801:b190:5302:8b46:f792 didn't accept a connection on 443 or 80 while others did. Remove them from DNS or fix that server — browsers that pick one wait for a timeout.
  3. Nameservers without IPv6
    ns1.dns-redirect.com, ns2.dns-redirect.com 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.

Browsers on dual-stack networks will usually pick IPv6 here (the "Happy Eyeballs" algorithm races both and prefers v6).
