Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: eur2.akam.net: "48878.30"; eur5.akam.net: "48878.26"; eur6.akam.net: "41824.7"; ns1-125.akam.net: "41824.10"; ns1-125.akam.net: "41824.4"; ns1-25.akam.net: "41824.7"; ns1-25.akam.net: "41824.10"; usc2.akam.net: "48878.29"; use2.akam.net: "41824.10"; use5.akam.net: "48878.27"; use5.akam.net: "48878.31". Hide or replace the version string.

Unusual SOA timers

SOA · refresh 15m is outside 20m–1d. Current values: refresh 15m, retry 10m, expire 14d, negative TTL 5m.

#23
!

Very low TTLs

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

Signatures expire in 71h0m0s

DNSSEC · DNSKEY signatures expire at 2026-10-24T20:34:40Z (in 71h0m0s). Check that re-signing works.

1024-bit DKIM key

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

Not configured

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.
