Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: eur2.akam.net: "48878.33"; eur5.akam.net: "48878.33"; eur6.akam.net: "41824.11"; ns1-125.akam.net: "41824.11"; ns1-125.akam.net: "41824.5"; ns1-25.akam.net: "41824.7"; ns1-25.akam.net: "41824.6"; usc2.akam.net: "48878.26"; use2.akam.net: "41824.11"; use5.akam.net: "48878.29". Hide or replace the version string.

SOA · refresh 5m is outside 20m–1d; expire 5d is shorter than 7d; secondaries stop answering too soon when the primary is down. Current values: refresh 5m, retry 3m, expire 5d, negative TTL 5m.

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 1d and in the zone 15m; resolvers may use either.

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

DNSSEC · DNSKEY signatures expire at 2026-10-24T14:11:18Z (in 55h0m0s). Check that re-signing works.

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