Creating NS Records

Updated on

Only create the required NS records for your delegated subdomain; all other DNS records are created by iPost, including A, MX, and TXT records for SPF, DKIM, DomainKeys, and DMARC.

For Registar Control Panels Such As GoDaddy

  1. Choose the parent domain (e.g.“websitename.com”) and click Edit or Manage DNS.
  2. Select Add or Create New Record.
  3. For Type, select NS.
  4. For Host, type in the subdomain name (e.g., for news.rootdomain.com, use 'news').
  5. For Value, enter dns01.ipost.com
  6. For TTL (Time To Live) - this is the amount of time the server should cache information before refreshing - the default is 1 hour or 3600.
  7. Click Save.
  8. Repeat steps 2-6 using dns01.smf.ipost.com as the Value.
  9. Click Save.
  10. There should now be two NS records under your root domain's DNS control panel.

For more information on your specific registar's process, see our section regarding provider-specific instructions.

For UNIX-based Systems

Using the BIND name server software, you would add the following records to the example.com zone file (do NOT create a new zone file for news.example.com itself):

news IN NS dns01.ipost.com.
news IN NS dns01.smf.ipost.com.
Click to copy
  • The trailing periods on dns01.ipost.com. and dns01.smf.ipost.com.com. are significant. “Glue records” are unnecessary in this setup because the nameservers for the subdomain do not reside within the DNS namespace of the subdomain itself.
  • When updating a zone file, including adding new records, you must be sure to update the Serial Number in the SOA record that controls the zone. If you don’t know what this means, get help from your IT professional.

For Administering DNS Under Windows

  1. Go into in the DNS management console.
  2. Right click on the parent zone (i.e. example.com).
  3. Select New Delegation.
  4. Follow the wizard instructions to create a delegation for “news” using these name servers:
dns01.ipost.com 64.84.6.50 
dns01.smf.ipost.com 204.94.81.2
Click to copy

What to do if NS records cannot be created

In the event that delegation records cannot be created for technical or policy reasons (e.g., Squarespace and Wix do not allow delegating NS records), the subdomain can be created as a CNAME (canonical name) record instead. Read on for more information regarding CNAME records and the extra steps involved in this process.
