By default, transfer of DNS zones is allowed only for name servers designated by NS records contained within each zone. If your domain name registrar requires that you allow transfer for all zones you serve, adjust the restrictions on DNS zones transfer as described below.
To define hosts to which DNS zone transfers are allowed:
- Go to Tools & Settings > DNS Template.
- Click Transfer Restrictions Template. A screen will show all hosts to which DNS zone transfers for all zones are allowed.
- Click Add Address.
- Specify the registrar's IP or network address and click OK.
