Delegation · The addresses at the parent (glue) differ from the addresses in the zone: ns1.nbcuni.com (glue 156.154.64.31, zone 156.154.64.31, 2001:502:f3ff::31); ns2.nbcuni.com (glue 156.154.65.31, zone 156.154.65.31, 2610:a1:1014::31); ns3.nbcuni.com (glue 156.154.66.31, zone 156.154.66.31, 2610:a1:1015::31); ns4.nbcuni.com (glue 156.154.67.31, zone 156.154.67.31, 2001:502:4612::31); ns5.nbcuni.com (glue 156.154.68.31, zone 156.154.68.31, 2610:a1:1016::31); ns6.nbcuni.com (glue 156.154.69.31, zone 156.154.69.31, 2610:a1:1017::31). Update the glue at your registrar.

SOA · refresh 15m is outside 20m–1d; retry 1h should be shorter than refresh 15m. Current values: refresh 15m, retry 1h, expire 30d, negative TTL 15m.

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 (1m39s), MX (1m39s), NS (1m39s). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1m39s; resolvers may use either.

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: mxa-00176a04.gslb.pphosted.com, mxb-00176a04.gslb.pphosted.com, mx0a-00176a04.pphosted.com, mx0b-00176a04.pphosted.com

DMARC · DMARC subdomain policy is sp=none, so spoofed mail from subdomains is not blocked. Consider sp=quarantine or sp=reject.

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.
