  • ✗
    Zone transfer allowed
    Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: ns1.yunohost.org (91.224.148.93): 115173 records; ns1.yunohost.org (2a03:7220:8080:5d00::1): 115173 records. Restrict zone transfers to your secondary servers.

    NS sets differ
    Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns2.yunohost.org. ns0.yunohost.org, ns1.yunohost.org, ns2.yunohost.org report NS ns0.yunohost.org ns1.yunohost.org ns2.yunohost.org.
    #7
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns0.yunohost.org: "9.20.29-1~deb13u1-Debian"; ns1.yunohost.org: "9.18.30-0ubuntu0.20.04.2-Ubuntu"; ns2.yunohost.org: "9.20.29-1~deb13u1-Debian". Hide or replace the version string.

    Unusual SOA timers
    SOA · negative caching TTL (minimum) 10s is outside 5m–1d (RFC 2308 recommends 1–3 hours). Current values: refresh 3h, retry 1h, expire 7d, negative TTL 10s.
    #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.
