Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-139.akam.net: "41824.4"; a1-139.akam.net: "41824.8"; a13-66.akam.net: "41824.11"; a13-66.akam.net: "41824.4"; a26-67.akam.net: "48878.29"; a26-67.akam.net: "48878.27"; a28-64.akam.net: "48878.29"; a28-64.akam.net: "48878.26"; a4-65.akam.net: "48878.33"; a4-65.akam.net: "48878.26"; a9-66.akam.net: "41824.10"; a9-66.akam.net: "41824.11". Hide or replace the version string.

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. The NS TTL at the parent is 2d and in the zone 10m; resolvers may use either.

DMARC · DMARC policy is set to 'quarantine'. Consider upgrading to 'reject' for stronger protection once you've verified legitimate emails are passing authentication.

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

DNSSEC · DNSKEY signatures expire at 2026-10-25T10:12:12Z (in 71h0m0s). Check that re-signing works.

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.
