DNS records and worldwide DNS propagation checker

Free NS Lookup

When you perform a quick NS Lookup, our tool queries the DNS system to retrieve the NS (Name Server) records associated with the domain. The NS record contains information about the authoritative name servers responsible for the respective domain.

Nameserver Record Checker Online

We have developed a reliable tool that retrieves real-time information about the authoritative name servers responsible for a specific domain. It helps find where the actual DNS records for a domain are stored in seconds.

Our NS Lookup Tool comes to the rescue whenever the domain is not resolving or experiencing technical difficulties. It helps identify whether the problem lies with the domain's DNS setup or somewhere else.

Once you verify whether the domain’s nameserver configuration is correct, you can take the necessary steps to rectify the issue.

If you plan to move your website to a new hosting provider or transfer domain ownership, it will be helpful for you to perform NSlookup. Leverage our tool to check and update the nameservers—ensuring a seamless transition without service disruptions.

Ultimately—our powerful NS record checker is designed to offer valuable insights into your domain's authoritative nameservers, DNS configurations, and some understanding of overall DNS health

Frequently Asked Questions

Now if you have any queries on your mind related to nameserver lookup, then here’s everything to guide you.

What are authoritative name servers?

Authoritative name servers are “DNS servers” that contain up-to-date DNS records for a specific domain. They are essential for accurately resolving domain names to their corresponding IP addresses. The NS records reflect this.

  • Which DNS server is authoritative for that domain?
  • Which DNS server is authorized to handle the queries related to that domain?
  • Which DNS server contains the actual DNS records, or is the DNS server responsible for managing the DNS records for that domain?
  • Where to go to find the domain's IP address.

An example of an NS record may look like the following.

Record Type Value TTL
mydomain.com NS ns1.mydomain.com 3600

In the above example,

  • mydomain.com represents the domain of the record
  • NS represents the DNS record type.
  • ns1.mydomain.com represents the value of the record. That is the nameserver for that domain.
  • 3600 is TTL (time to live). It is the time for which the DNS server caches the record. On the expiry of that time, the server goes for the fresh DNS records data.

Why check nameserver records?

NS lookup is a fundamental Domain Name System (DNS) aspect. It lets you discover the authoritative nameservers handling DNS queries for a specific domain.

Why is NS Lookup important for webmasters?

NS Lookup is helpful for website owners as it helps ensure that a domain's DNS settings are correctly configured. It allows them to quickly verify if the domain is pointing to the right name servers and troubleshoot potential DNS-related issues that may affect website accessibility.

Can an NS Lookup be used to find the IP address of a website directly?

No. The NSlookup online does not directly provide the IP address of any website. It only returns the authoritative name servers associated with the given domain. To find the IP address of a website, you need to perform an A record lookup after obtaining the authoritative name servers.

Are there any limitations to using our online NSlookup tool?

Our NSLookup tool is one of the most dynamic tools, with unlimited queries and the most detailed information at no cost. Other tools limit the no. of queries, and some are paid. Our tool is above all these limitations. 

Why does nslookup show you more than 1 IP address?

NSlookup shows you more than 1 IP address (most of the time 2 IP Addresses) because of load balancing. 

Can I change the authoritative name servers for my domain?

Yes. It is possible to change the authoritative name servers for your domain. You must access your domain registrar or hosting provider's control panel. But you must be cautious while making such changes, as incorrect configurations can lead to DNS downtime or traffic misrouting. Do it only when necessarily required.

How long does it take for Name Server changes to propagate?

Name server changes generally take some time ranging from minutes to hours, to propagate across the internet. This process is known as DNS propagation, and its period depends on various factors, such as the Time-to-Live (TTL) setting in the DNS records and the caching behavior of other DNS servers. Use the WhatsMyDNS tool to check whether these changes are fully propagated around the globe.

Is there a command line for NS Lookup on Linux and macOS systems?

Yes. The "dig" (Domain Information Groper) command is commonly used for DNS queries, including NS Lookups on Linux and Mac. The syntax is typically: dig NS yourdomain.com.

What to do if it shows incorrect authoritative name servers for a domain?

If the NS Lookup shows inaccurate authoritative name servers, it may indicate DNS misconfiguration or other issues. It is recommended to contact your domain registrar or hosting provider's support team to report the problem and seek assistance in resolving the issue.

What if I get Cloudflare DNS Servers while performing the NS Lookup for any domain?

There are a few things for you to understand. Obtaining the Cloudflare DNS servers while performing the Namer server record check does not mean that Cloudflare is the authoritative name server for that domain. If the domain is using Cloudflare's DNS services, then Cloudflare's name servers will be listed as the authoritative name servers in the NS Lookup results. However, this does not necessarily mean Cloudflare is the domain's primary authoritative name server. The domain's owner can configure the authoritative name servers to point to any provider they choose.

Do all domains have the same number of Name Servers?

No. The number of name servers for a domain can vary. Some domains have only two name servers (primary and secondary), whereas others may have more. This depends on the hosting provider's configuration or the domain owner's preferences.

What is the difference between DNS and nslookup?

The DNS stands for Domain Name System or Domain Naming System, Domain Name Service. It is a global system that translates IP addresses to human-readable domain names. On the other hand, a nameserver is used to locate the DNS server. A nameserver is the address of the DNS server that hosts the records for that domain. An NS lookup checks the NS records associated with a domain.
