Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: a18-64.akam.net, a22-65.akam.net, a3-66.akam.net, a8-67.akam.net. a1-4.akam.net, a13-67.akam.net, a18-64.akam.net, a22-65.akam.net, a3-66.akam.net, a8-67.akam.net report NS a1-4.akam.net a13-67.akam.net a18-64.akam.net a22-65.akam.net a3-66.akam.net a8-67.akam.net.

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-4.akam.net: "41824.8"; a1-4.akam.net: "41824.9"; a13-67.akam.net: "41824.9"; a13-67.akam.net: "41824.11"; a18-64.akam.net: "48878.30"; a18-64.akam.net: "48878.27"; a22-65.akam.net: "48878.30"; a22-65.akam.net: "48878.32"; a3-66.akam.net: "41824.8"; a3-66.akam.net: "41824.10"; a8-67.akam.net: "48878.30"; a8-67.akam.net: "48878.33". 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 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: maersk-com.mail.protection.outlook.com

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: mail (1024 bits), selector1 (1024 bits), s2 (1024 bits). Rotate to a 2048-bit key.
