Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: pdns5.ultradns.info, pdns6.ultradns.co.uk. dns1.p09.nsone.net, dns2.p09.nsone.net, dns3.p09.nsone.net, dns4.p09.nsone.net, pdns1.ultradns.net, pdns2.ultradns.net, pdns3.ultradns.org, pdns4.ultradns.org, pdns5.ultradns.info, pdns6.ultradns.co.uk report NS dns1.p09.nsone.net dns2.p09.nsone.net dns3.p09.nsone.net dns4.p09.nsone.net pdns1.ultradns.net pdns2.ultradns.net pdns3.ultradns.org pdns4.ultradns.org pdns5.ultradns.info pdns6.ultradns.co.uk.

SOA · The nameservers serve different versions of the zone: 1650656827 on pdns1.ultradns.net (204.74.108.1), pdns1.ultradns.net (2001:502:f3ff::1), pdns2.ultradns.net (204.74.109.1), pdns2.ultradns.net (2610:a1:1014::1), pdns3.ultradns.org (199.7.68.1), pdns3.ultradns.org (2610:a1:1015::1), pdns4.ultradns.org (199.7.69.1), pdns4.ultradns.org (2001:502:4612::1), pdns5.ultradns.info (204.74.114.1), pdns5.ultradns.info (2610:a1:1016::1), pdns6.ultradns.co.uk (204.74.115.1), pdns6.ultradns.co.uk (2610:a1:1017::1); 1650656844 on dns1.p09.nsone.net (198.51.44.9), dns1.p09.nsone.net (2620:4d:4000:6259:7:9:0:1), dns2.p09.nsone.net (198.51.45.9), dns2.p09.nsone.net (2a00:edc0:6259:7:9::2), dns3.p09.nsone.net (198.51.44.73), dns3.p09.nsone.net (2620:4d:4000:6259:7:9:0:3), dns4.p09.nsone.net (198.51.45.73), dns4.p09.nsone.net (2a00:edc0:6259:7:9::4). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

DNSSEC · The zone is not signed with DNSSEC, so answers can be spoofed. Enable DNSSEC at your DNS provider and publish the DS record at your registrar.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change.

DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

MX · The following MX hosts could not be resolved to IPv6 addresses: mxa.expediagroup.com, mxb.expediagroup.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), k1 (1024 bits), selector1 (1024 bits), selector2 (1024 bits). Rotate to a 2048-bit key.

TLS · MTA-STS is not configured, so other mail servers fall back to unencrypted delivery when TLS fails or is stripped by an attacker. Publish a _mta-sts TXT record and a policy at https://mta-sts.<domain>/.well-known/mta-sts.txt.
