How this service works
Nameserver health of a domain: count, provider diversity, whether each nameserver resolves, and the SOA serial.
Output
Returns a structured report including the domain name, list of nameservers with per-nameserver resolution status and detected provider, the set of distinct DNS providers (provider diversity), an overall health verdict, a degraded flag, reasons for any issues, and the SOA record with fields including serial, primary NS, contact, refresh, retry, expire, and minimum TTL. Also includes a summary string, timestamp, and optional disclaimer.
Example use cases
Pre-launch DNS infrastructure audit
“Before we go live, can you check the nameserver health of mystartupdomain.com — I want to confirm all nameservers resolve, see how many we have, and check if we're relying on just one DNS provider?”
Diagnosing intermittent DNS outages
“We're seeing intermittent DNS failures for acmecorp.com — can you check the nameserver health, see which ones are resolving and which aren't, and give me the SOA serial so I can compare with our registrar?”
Monitoring competitor DNS redundancy
“Can you pull the nameserver health report for competitor.com? I want to see how many nameservers they have, how many different DNS providers, and whether there are any degraded nameservers.”
Technical details
Endpoint
GEThttps://domain-dns.x402tookit.com/ns-health?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a focused, structured health check on a domain's nameserver layer specifically — covering resolution, provider diversity, and SOA data — rather than a full multi-record DNS dump. It is ideal for infrastructure audits, DNS redundancy checks, outage diagnosis, and monitoring workflows where nameserver reliability is the primary concern.
Side effects
- Domain does not exist — nameservers list may be empty and verdict reflects non-existence
- DNS resolution timeout — some nameservers marked as not resolving due to transient network issues
- Invalid domain input — malformed domain string causes error response
- All nameservers fail to resolve — degraded flag set to true with reasons listed
- SOA record unavailable — soa field returned as null
