Zone transfer allowed

Nameservers · These nameservers send the complete zone to anyone who asks (AXFR), exposing all host names: polaris.centre-cired.fr (193.51.120.2): 16 records. Restrict zone transfers to your secondary servers.

!

Nameservers in one network

Delegation · all IPv4 addresses are in 193.51.120.0/24. A single network failure takes all nameservers down; RFC 2182 recommends topologically separate networks (anycast setups are an exception).

#10
!

No IPv6

Delegation · None of the nameservers has an IPv6 address, so IPv6-only resolvers can't reach them.

#13
!

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

✗

No DMARC record

DMARC · No DMARC record was found for this domain. DMARC is essential for preventing email spoofing. Add a DMARC record with p=reject or at least p=quarantine.

#5
!

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.
