Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: edns1.ultradns.org. a1-189.akam.net, a2-64.akam.net, a24-66.akam.net, edns1.ultradns.biz, edns1.ultradns.com, edns1.ultradns.net, edns1.ultradns.org report NS a1-189.akam.net a2-64.akam.net a24-66.akam.net edns1.ultradns.biz edns1.ultradns.com edns1.ultradns.net edns1.ultradns.org.

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-189.akam.net: "41824.4"; a1-189.akam.net: "41824.6"; a2-64.akam.net: "48878.26"; a2-64.akam.net: "48878.30"; a24-66.akam.net: "48878.33"; a24-66.akam.net: "48878.30". Hide or replace the version string.

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

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

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-00004003.gslb.pphosted.com, mxb-00004003.gslb.pphosted.com, mx0a-00004003.pphosted.com, mx0b-00004003.pphosted.com

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.
