Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-182.akam.net: "41824.9"; a11-64.akam.net: "41824.11"; a11-64.akam.net: "41824.6"; a18-64.akam.net: "48878.33"; a24-67.akam.net: "48878.30"; a24-67.akam.net: "48878.33"; a6-66.akam.net: "48878.26"; a6-66.akam.net: "48878.32"; a7-66.akam.net: "41824.5"; a7-66.akam.net: "41824.11". Hide or replace the version string.

SOA · The nameservers serve different versions of the zone: 1657129353 on dns1.p01.nsone.net (198.51.44.1), dns1.p01.nsone.net (2620:4d:4000:6259:7:1:0:1), dns2.p01.nsone.net (198.51.45.1), dns2.p01.nsone.net (2a00:edc0:6259:7:1::2), dns3.p01.nsone.net (198.51.44.65), dns3.p01.nsone.net (2620:4d:4000:6259:7:1:0:3), dns4.p01.nsone.net (198.51.45.65), dns4.p01.nsone.net (2a00:edc0:6259:7:1::4); 2020583343 on a11-64.akam.net (84.53.139.64), a18-64.akam.net (95.101.36.64), a18-64.akam.net (2600:1480:4800::40), a24-67.akam.net (2.16.130.67), a6-66.akam.net (23.211.133.66); 2020583345 on a1-182.akam.net (193.108.91.182), a1-182.akam.net (2600:1401:2::b6), a11-64.akam.net (2600:1480:1::40), a24-67.akam.net (2600:1480:9800::43), a6-66.akam.net (2600:1401:1::42), a7-66.akam.net (23.61.199.66), a7-66.akam.net (2600:1406:32::42). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

SOA · retry 30m should be shorter than refresh 30m. Current values: refresh 30m, retry 30m, expire 7d, negative TTL 30m.

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), MX (30s). 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.

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: mx1.intuit.iphmx.com, mx2.intuit.iphmx.com

DKIM · 1024-bit RSA keys are the minimum and are considered weak today: default (1024 bits), mail (1024 bits), k1 (1024 bits), s2 (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.
