Sub-Domain Creation Between Two Accounts

This article describes how to create a sub-domain in one UltraDNS account and delegate it from another account.

Overview

Sub-domain delegation between two UltraDNS accounts requires creating the sub-domain zone in one account and configuring NS records in the parent domain in the other account.

Steps to Create the Sub-Domain

1. Create the sub-domain zone in the destination UltraDNS account.
2. Note the name servers assigned to the sub-domain zone.

Steps to Delegate the Sub-Domain

1. Log in to the UltraDNS account that manages the parent domain.
2. Open the parent domain zone.
3. Create NS records for the sub-domain.
4. Assign the NS records to the name servers of the sub-domain zone.

Verification

The delegation is complete when DNS queries for the sub-domain are answered by the name servers assigned to the sub-domain zone.

Important Notes

• The sub-domain zone must exist before delegation is configured.
• Incorrect or missing NS records will prevent the sub-domain from resolving.
• DNS propagation timing depends on TTL values.
