Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: a1-246.akam.net: "41824.5"; a1-246.akam.net: "41824.4"; a13-65.akam.net: "41824.10"; a13-65.akam.net: "41824.8"; a14-66.akam.net: "48878.33"; a18-67.akam.net: "48878.30"; a18-67.akam.net: "48878.26"; a24-64.akam.net: "48878.26"; a24-64.akam.net: "48878.27"; a3-65.akam.net: "41824.4". 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), AAAA (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.

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

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: mx3.justdial.com, mx5.justdial.com, mx6.justdial.com, mx7.justdial.com

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

MX · These MX addresses have no PTR record, which many receivers treat as a spam signal: 103.71.205.28 (mx6.justdial.com), 103.71.205.29 (mx7.justdial.com). Ask your hosting provider to set one.

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.
