Free NS Record Lookup

The NS Record Lookup is a free online tool that look up nameserver (ns) records for any domain. identify your dns provider instantly. It runs entirely in your browser with no installation or sign-up needed.

NS records delegate DNS resolution for a domain to specific nameservers.

To verify your DNS provider, troubleshoot propagation, or audit domain settings.

Most domains publish between two and four NS records, and that range exists for redundancy: if one authoritative nameserver is unreachable, resolvers fall back to another. ICANN requires at least two nameservers for a delegated domain, and many registrars and DNS providers add three or four by default. Having only one is a single point of failure, while more than four rarely adds meaningful resilience and just enlarges the response. Note that all of a domain's nameservers usually sit with the same provider, so the count reflects redundancy within that provider rather than across multiple ones. This tool shows the exact number of nameservers a domain publishes in a badge beside the results, so you can confirm at a glance whether a domain has healthy redundancy. Enter any domain to see its full nameserver count.

NS records and the SOA record both live at the top of a DNS zone, but they do different jobs. NS records list the authoritative nameservers that answer queries for the domain, telling the world where to send DNS questions. The SOA (Start of Authority) record names the primary nameserver and the zone's administrative email, and it carries the serial number and timers that govern how secondary servers refresh their copy of the zone. In short, NS records delegate, while SOA defines the zone's authority and replication settings. A healthy zone needs both: the registrar publishes NS records to point resolvers at your provider, and the provider publishes the SOA internally. This tool focuses on the NS side, returning the authoritative nameservers and their TTLs so you can confirm where a domain is delegated. Enter a domain to view its NS records.

The fastest way is to look at the domain's NS records, because the nameserver hostnames reveal the DNS provider. A value like dana.ns.cloudflare.com points to Cloudflare, awsdns hostnames belong to AWS Route 53, and domaincontrol.com signals GoDaddy. Recognizing these patterns by eye takes experience, so this tool does it for you: it reads the live NS records and automatically labels the detected provider with a badge for Cloudflare, AWS Route 53, Google Cloud DNS, Azure DNS, GoDaddy, Namecheap, and NS1. If a domain uses a provider outside that set, the nameservers are still shown in full so you can identify the host from the hostname yourself. This matters before a migration, when auditing an inherited domain, or when DNS edits aren't taking effect because the zone lives elsewhere. Enter a domain to see its nameservers and detected provider.

When you change nameservers at your registrar, the update has to propagate before resolvers worldwide see it, and that can take up to 24 to 48 hours. During this window, some networks return the old NS records while others return the new ones, depending on what each resolver has cached. The TTL on the previous records influences how long old values linger, since resolvers may keep a cached answer until it expires. Checking the NS records is the clearest way to tell whether the switch has gone through where you are. This tool queries Cloudflare's public DNS resolver for live, authoritative data and lists each nameserver with its TTL, so you can confirm the new values have taken effect and see how long records are cached. Run a lookup periodically after a change to watch the migration complete.

Yes. Network engineers traditionally run dig NS example.com or nslookup -type=ns example.com from a terminal, but you don't need a command-line resolver installed to get the same answer. This tool performs the lookup in your browser and returns the results in a readable list, no syntax to remember. Paste a bare domain, or even a full URL with https:// or www. in front, and the tool strips those automatically before querying the bare domain. It then shows each authoritative nameserver, its TTL in seconds, the total nameserver count, and a detected provider label, with a Copy All button to grab the full list at once. Behind the scenes it uses Cloudflare's DNS-over-HTTPS resolver, so the data is live and authoritative rather than cached locally. Enter a domain to look up its nameservers instantly.
