Glue differs from the zone

Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ashe.skillshare.com (glue 173.245.58.42, zone 173.245.58.42, 2400:cb00:2049:1::adf5:3a2a); garen.skillshare.com (glue 173.245.59.36, zone 173.245.59.36, 2400:cb00:2049:1::adf5:3b24). 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: ashe.skillshare.com: "2026.10.2"; garen.skillshare.com: "2026.10.2". 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

✗

Weak DKIM key

DKIM · RSA keys shorter than 1024 bits can be cracked and are ignored by receivers (RFC 8301): pm (768 bits). Rotate to a 2048-bit key.

#23
!

Not enabled

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

#8
!

More than 5 MX records

MX · Found 7 MX records, which is more than the recommended maximum of 5. Too many MX records may indicate a misconfiguration.

#13
!

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.
