Domain name system (DNS) is the system that is used to translate human-memorable domain names like namecheap.com and hostnames like support.namecheap.com into the corresponding numeric Internet Protocol (IP) addresses as well as to identify and locate computer systems and resources on the Internet 



REGISTRAR

First, determine which registrar the domain is registered with because this controls everything else with the domain.


How to find out the registrar for a domain:

  1. Go to http://centralops.net and search for the domain.
  2. The registrar will be listed under the Domain Whois Section and will be listed after "Registrar:".


NAME SERVERS

Next, determine which name servers the registrar points to. If the name servers point to somewhere other than where the domain is registered, then the DNS changes


To find the name servers a domain is using:

  1. Go to http://centralops.net and search for the domain.
  2. The name servers will be listed under the Domain Whois Section and will be listed after "Name servers:".



Example: Truspeed.ca


Registrar:



Name Sever:


In this case, the Registrar is Rebel (so we do the domain registration) and since the Name Sever is also pointed to Rebel, we also manage their DNS records.
