    Serials differ
    SOA · The nameservers serve different versions of the zone: 1 on ns-1087.awsdns-07.org (205.251.196.63), ns-1087.awsdns-07.org (2600:9000:5304:3f00::1), ns-1877.awsdns-42.co.uk (205.251.199.85), ns-1877.awsdns-42.co.uk (2600:9000:5307:5500::1), ns-394.awsdns-49.com (205.251.193.138), ns-394.awsdns-49.com (2600:9000:5301:8a00::1), ns-949.awsdns-54.net (205.251.195.181), ns-949.awsdns-54.net (2600:9000:5303:b500::1); 1783450017 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). This is normal for a few minutes after a change; if it lasts, zone transfers to the secondaries are failing.

  • !
    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.
    #27
  • !
    Very low TTLs
    Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (4m32s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1d and in the zone 1h; resolvers may use either.

    No DKIM keys published
    DKIM · _domainkey.airbnb.de does not exist (NXDOMAIN), so no DKIM keys are published. DKIM helps prevent email spoofing. Configure DKIM with your email service provider.

    Not enabled
    DNSSEC · DNSSEC is not enabled for this domain. Consider enabling DNSSEC to protect against DNS spoofing attacks.

    No MX records
    MX · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
