    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns-1533.awsdns-63.org, ns-1580.awsdns-05.co.uk, ns-523.awsdns-01.net, ns-79.awsdns-09.com. ns-1533.awsdns-63.org, ns-1580.awsdns-05.co.uk, ns-523.awsdns-01.net, ns-79.awsdns-09.com, ns1-35.azure-dns.com, ns2-35.azure-dns.net, ns3-35.azure-dns.org, ns4-35.azure-dns.info report NS ns-1533.awsdns-63.org ns-1580.awsdns-05.co.uk ns-523.awsdns-01.net ns-79.awsdns-09.com ns1-35.azure-dns.com ns2-35.azure-dns.net ns3-35.azure-dns.org ns4-35.azure-dns.info.

    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns2-35.azure-dns.net: "Knot DNS 3.1.2.1770717641.d6b376aff"; ns4-35.azure-dns.info: "Knot DNS 3.1.2.1770717641.d6b376aff". Hide or replace the version string.

    Serials differ
    SOA · The nameservers serve different versions of the zone: 1 on ns-1533.awsdns-63.org (205.251.197.253), ns-1533.awsdns-63.org (2600:9000:5305:fd00::1), ns-1580.awsdns-05.co.uk (205.251.198.44), ns-1580.awsdns-05.co.uk (2600:9000:5306:2c00::1), ns-523.awsdns-01.net (205.251.194.11), ns-523.awsdns-01.net (2600:9000:5302:b00::1), ns-79.awsdns-09.com (205.251.192.79), ns-79.awsdns-09.com (2600:9000:5300:4f00::1); 2019012973 on ns1-35.azure-dns.com (150.171.10.35), ns1-35.azure-dns.com (2603:1061:0:10::23), ns2-35.azure-dns.net (150.171.16.35), ns2-35.azure-dns.net (2620:1ec:8ec:10::23), ns3-35.azure-dns.org (13.107.222.35), ns3-35.azure-dns.org (2a01:111:4000:10::23), ns4-35.azure-dns.info (13.107.206.35), ns4-35.azure-dns.info (2620:1ec:bda:10::23). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

    Unusual SOA timers
    SOA · negative caching TTL (minimum) 2d is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 1d, retry 2h, expire 1000h, negative TTL 2d.
    #23
  • !
    Not signed
    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.

Problems

  • !
    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.
    #8
  • !
    Single MX host, no backup
    MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.
    #12
  • !
    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.
