Delegation · The nameservers at the parent and in the zone should be the same. Only in the zone: ns5.bnpparibas.com. ns1.bnpparibas.com, ns2.bnpparibas.com, ns3.domivesta.net, ns4.domivesta.com, ns5.bnpparibas.com report NS ns1.bnpparibas.com ns2.bnpparibas.com ns3.domivesta.net ns4.domivesta.com ns5.bnpparibas.com.

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns1.bnpparibas.com: "41824.9"; ns1.bnpparibas.com: "41824.5"; ns1.bnpparibas.com: "41824.7"; ns2.bnpparibas.com: "41824.11"; ns2.bnpparibas.com: "41824.5"; ns2.bnpparibas.com: "41824.8"; ns3.domivesta.net: "48878.26"; ns3.domivesta.net: "48878.29"; ns3.domivesta.net: "48878.31"; ns4.domivesta.com: "48878.33"; ns4.domivesta.com: "48878.26"; ns4.domivesta.com: "48878.31"; ns5.bnpparibas.com: "48878.32". Hide or replace the version string.

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.

Records · These records have a TTL below 5m, causing extra queries and slower lookups: A (20s), AAAA (20s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 1h and in the zone 4h; resolvers may use either.

DKIM · The _domainkey name exists but no DKIM key was found under the common selectors. Selectors are provider-specific; check yours with -selector.

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

MX · The following MX hosts could not be resolved to IPv6 addresses: smtp-in-internet-usr-m.gslb.srv.bnpparibas

MX · Only one MX record found. For better email reliability, consider adding at least one backup MX server.

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.
