NS Records

What are NS Records?
NS Records indicate which name servers are authoritative for a domain or subdomain. NS Records are used in the event that another external DNS provider will be used in conjunction with Constellix DNS. They can also be used if a sub domain delegation will take place to external name servers. In most cases, no NS records need to be added for a domain as Constellix DNS defines the Constellix name servers under the system NS records section.
Please note, the value field must end in a dot (.) in order to keep the music.com domain from being appended to the end of the value.

How to Configure NS Records
1.Select Managed DNS and click on Domains

2. Select the Domain Name you want to add an NS record too. 
3. Under the NS Records section, click the (+) to add a record.
 NS Record Fields 

A) Name: This will be the host name for the record, typically a computer or server within your domain. It is important to note, the domain name is automatically appended to the “Name” field of the record. For example, defining www.constellixtesting.com in DNS would be making the name field of “www” within the constellixtesting.com domain. Do not leave the name field blank this record type is not for the root only for subdomains to delegate out to another name server 

B) TTL: The TTL (Time to Live) in seconds is the length of time the record will cache in resolving name servers and web browsers. The longer the TTL, then remote systems will lookup the DNS record less frequently. Your name servers will also receive less query traffic since most queries are answered by resolving name servers. Conversely, the shorter the TTL the faster any changes you make to your DNS will propagate in servers that have cached data. However, your domain will receive more query traffic.

C) Host: This will be the host name for the name server, for example ns0.nameserver.com. It is important to note, the domain name is automatically appended to the end of this field unless it ends with a dot (.).

D) Notes: Add a helpful note with keywords so you can search for your records later.

E) Save: Save your record changes and don’t forget to commit your changes after you’re done making record changes for this domain!
