Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns51.constellix.net, ns61.constellix.net. ns11.constellix.com, ns21.constellix.com, ns31.constellix.com, ns41.constellix.net, ns51.constellix.net, ns61.constellix.net report NS dns1.p08.nsone.net dns2.p08.nsone.net dns3.p08.nsone.net dns4.p08.nsone.net ns11.constellix.com ns21.constellix.com ns31.constellix.com ns41.constellix.net ns51.constellix.net ns61.constellix.net.

SOA · The nameservers serve different versions of the zone: 1659608435 on dns1.p08.nsone.net (198.51.44.8), dns1.p08.nsone.net (2620:4d:4000:6259:7:8:0:1), dns2.p08.nsone.net (198.51.45.8), dns2.p08.nsone.net (2a00:edc0:6259:7:8::2), dns3.p08.nsone.net (198.51.44.72), dns3.p08.nsone.net (2620:4d:4000:6259:7:8:0:3), dns4.p08.nsone.net (198.51.45.72), dns4.p08.nsone.net (2a00:edc0:6259:7:8::4); 2015011820 on ns11.constellix.com (96.45.80.1), ns11.constellix.com (2600:180a:1001::1), ns21.constellix.com (46.31.236.1), ns21.constellix.com (2600:180b:2001::1), ns31.constellix.com (43.247.170.1), ns31.constellix.com (2600:180c:3001::1), ns41.constellix.net (96.45.81.1), ns41.constellix.net (2600:180a:4001::1), ns51.constellix.net (46.31.237.1), ns51.constellix.net (2600:180b:5001::1), ns61.constellix.net (43.247.171.1), ns61.constellix.net (2600:180c:6001::1). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

SOA · refresh 5m is outside 20m–1d; retry 5m should be shorter than refresh 5m. Current values: refresh 5m, retry 5m, expire 14d, negative TTL 1h.

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 (15s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; resolvers may use either.

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: mur.timeanddate.com, mx1.dnsmadeeasy.com, mx2.dnsmadeeasy.com, mx3.dnsmadeeasy.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: k1 (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.
