NS Lookup: Check The Name Server of a Domain
With EXPERTE.com's NS Lookup, you can easily fetch a domain's name server entries in no time. To get started, just enter the domain you want to check in the uppermost field.
After that, you'll receive a table containing the domain's NS entries. In the event that you would prefer to determine the IP of a domain (A- and AAAA entries), please use our DNS Check instead.
NS Entry - Structure
A name server entry tells you which name server is responsible for a particular domain.
NS entries are structured as follows:
Domain for which the entry is
Name of the authoritative name server for this domain
Time to live (how long the entry should remain in the cache)
NS Lookup - Process
In order to determine the name server for a domain, such as experte.de, our tool does the following:
- 1.The client or DNS resolver requests the name server entry for the domain (in our case, experte.de) from a so-called root name server. This replies with the following data:
- 2.The client or DNS resolver now requests the name server entries from the DNS server that is responsible for the .de zone. This, in turn, answers with the following information:
- 3.(Optional) The client or DNS resolver can now determine the IP address for the domain (experte.de) by requesting the A record from the name server tom.ns.cloudflare.com or coco.ns.cloudflare.com.
