NS Lookup

Lookup Nameserver records of any domain. Use the nameserver checker to check the NS records of any domain.

NS Lookup Tool - NS Checker to Check the Nameservers of a domain

Nameserver lookup or NS Lookup tool is an NS checker for getting nameserver records of any domain name. NS is a record type of DNS, and it is set up via a hosting provider. Whenever a browser sends a DNS request to a DNS server, it sends back the nameserver records, and the nameservers are then used to get the actual IP address behind a domain name. So, it's handy to check website nameservers to verify if they are correctly entered in your hosting management interface to avoid downtime.

How can the domain nameserver lookup be performed to check if nameservers for a domain are pointed correctly?

Note down your domain's nameservers. After the NS records updates or change, it takes a few hours to reflect them fully. Go to the nameserver checker for NS lookup and enter a domain name to check that the domain's nameservers are now pointed correctly.

What are a nameserver and its purpose?

NS stands for the nameserver. NS records are the nameserver records that contain the information of the nameservers associated with the domain.

These are the DNS records type that indicates

  • 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

  • com represents the domain of the record
  • NS represents the DNS record type.
  • 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.

The nameserver can never point to the canonical name (CNAME) record.

Can one domain have multiple nameservers?

The domain is often configured for multiple NS records. These are the Primary and secondary NS records.

The multiple NS records indicate the domain's primary and secondary (backup) nameservers. If the primary nameserver cannot respond, the secondary nameserver responds to that query.

Typically, there is one primary nameserver, and several secondary nameservers store the exact copy of the primary nameserver's DNS records. Updating the primary nameserver's record will also trigger the update of the secondary nameservers.

The website, email, or other domain services will not work without adequately configured NS records. The user will be unable to load a website or application.

An example of multiple NS records may look like the following.

Record Type Value TTL
google.com NS ns1.google.com 3600
google.com NS ns2.google.com 3600

How many nameservers can a domain have?

At a minimum, you need only two DNS servers for each domain. You can extend this to more than two for your domain, but usually, three is the maximum unless you have multiple server farms where you would want to share the DNS lookup load.

When should NS records be updated or changed?

Domain administrator(s) should update their NS records when they need to change their nameservers. They can also update their NS records when they want their subdomain to point to the secondary nameserver.

In the example above, the primary nameserver for mydomain.com is ns1.mydomain.com. If the mydomain.com admin wanted blog.mydomain.com to resolve through ns1.mydomain.com, they could set this up by updating the NS records.

When NS records are updated, it may take several hours to replicate the changes throughout the DNS. Usually, it takes 48 hours. After that time, perform the DNS Propagation through WhatsMyDNS tool to check whether these changes are fully propagated around the globe.


Where are your domain's nameservers located?

When you register your domain through a domain registrar, your domain is usually first pointed to your domain registrar's nameservers.

Your domain registrar is the place where you can edit your domain's nameservers. If you want to use these nameservers, edit your DNS records to point your domain name toward your hosting provider.

But experts suggest you use the nameservers provided by your web hosting. However, it depends upon your requirements and needs.

Are DNS and nameserver the same?

The DNS stands for Domain Name System or Domain Naming System, Domain Name Service, depending upon whom you talk to. 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 server checks the NS records associated with a domain. One can perform a DNS server lookup if one wants to fetch all the DNS records associated with a domain.
