Nameserver Checker

Audit any domain's authoritative nameservers and catch single-point-of-failure DNS risk before it bites you.

Live on the Apify Store — run it instantly or call it as an agent tool via Apify MCP.

What you get

Authoritative nameservers (dns.resolveNs), deduped and sorted
Each nameserver resolved to its A/AAAA IPs
Provider count, by grouping nameservers on their registrable base domain
Redundancy verdict (redundancyOk) plus a plain-English issues list flagging:
- fewer than 2 nameservers
- all nameservers on a single provider
- all nameserver IPs in the same /24 subnet (low network redundancy)
Single domain or bulk; capped per run with maxDomains

Input

{
  "domain": "github.com",
  "domains": ["google.com", "cloudflare.com"],
  "maxDomains": 50
