Problems

  • ✗
    Nameserver names are CNAMEs
    Delegation · Nameserver names must not be aliases (RFC 2181 10.3): ns3.odiso.net -> ns1.odiso.net.
    #9
  • !
    Nameservers in one network
    Delegation · all IPv4 addresses are in 89.248.211.0/24; all IPv6 addresses are in 2a0a:1580:2000::/48. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).
    #10
  • !
    Software version disclosed
    Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.odiso.net: "PowerDNS Authoritative Server 4.8.5 (built Feb 7 2025 09:21:19 by root@localhost)"; ns2.odiso.net: "PowerDNS Authoritative Server 4.8.5 (built Feb 7 2025 09:21:19 by root@localhost)"; ns3.odiso.net: "PowerDNS Authoritative Server 4.8.5 (built Feb 7 2025 09:21:19 by root@localhost)". Hide or replace the version string.
    #17
  • !
    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
  • !
    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.
