Glue differs from the zone

Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1-39.azure-dns.com (glue 150.171.10.39, zone 150.171.10.39, 2603:1061:0:10::27). Update the glue at your registrar.

Software version disclosed

Nameservers · These nameservers report their software version via version.bind/version.server, which helps attackers find known vulnerabilities: ns2-39.azure-dns.net: "Knot DNS 3.1.2.1770717641.d6b376aff"; ns4-39.azure-dns.info: "Knot DNS 3.1.2.1770717641.d6b376aff". Hide or replace the version string.

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.
