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 · retry 1d should be shorter than refresh 1d; expire 1d is shorter than 7d; secondaries stop answering too soon when the primary is down; expire 1d must be longer than refresh + retry. Current values: refresh 1d, retry 1d, expire 1d, negative TTL 1d.

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). Low TTLs are useful just before a planned change. The NS TTL at the parent is 2d and in the zone 1d; 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 · No MX records found. If this domain is used for email, add MX records to specify mail servers. If it never receives mail, publish a null MX ("MX 0 .").
