A subdomain is technically defined as when you assign a different section of name servers for part of a domain. For instance “dnsmadeeeasy.com.” is a subdomain for “com.”. Creating “sub.dnsmadeeasy.com.” on a different group of name servers than “dnsmadeeasy.com.” would be creation of a subdomain. In contrast, “www.dnsmadeeasy.com.” is a record with the name of “www” within the domain “dnsmadeeasy.com”.

You would create a subdomain for “sub.dnsmadeeasy.com.” rather than a record if for example, “sub.dnsmadeeasy.com.” will be assigned to different name servers than “dnsmadeeasy.com.”

We will create the subdomain “sub.example.com” as a subdomain of the root domain “example.com” and delegate it to the name servers ns0-ns4.nameserver.com.

Step 1: Select Managed DNS

Step 2: Select a domain

Select a domain from the either the “Recently Updated Domains” box, or start typing the domain name in the textbox on the “Select Domain” tab.

Step 3: Add an NS record

Scroll down to the NS records for the domain and click on the plus sign to add a new NS Record

Add NS Record

Step 4: Insert NS values

Create additional NS records that delegate “sub” to each of the name servers it will be assigned. Each name server host name must end in a dot (.) to keep your domain name from being appended to the end.

Step 5: This will be the complete list of NS records once the delegation is complete

Step 6: The resulting list of name servers would be:
