Delegating a Public DNS Zone

Make an OCI public DNS zone accessible through the internet.

In this step, delegate  the domain  with a registrar. A domain name registrar is a company that manages the reservation of internet domain names. Delegating a domain with a registrar makes the OCI hosted zone  accessible through the internet.

OCI isn't a registrar. However, you can delegate OCI DNS zones with registrars such as VeriSign or GoDaddy.

See Overview of DNS and Public DNS for more information.

Using the Console

  1. Open the navigation menu and click Networking. Under DNS management, click Zones.
  2. Click the Zone name for the zone you want to delegate. The zone details page appears.
  3. In Resources, click Records. A list of records appear.
  4. Use the Type sort filter to find the NS records for the zone.
  5. Note the name servers in the RDATA  field within each NS record.
  6. Visit the third-party registrar you chose and follow the registrar vendor's specific documentation to change the domain's DNS delegation. You need the name servers noted in step 5 to complete the process.
    Note

    After delegation has completed, it can take 24 to 48 hours for resolvers to recognize that a new set of NS records is in delegation. This is because NS records can have long TTL values and they must expire before the new NS records can replace them.
Tip

Use the Domain Information Groper (dig) command line tool to test against the delegation  where the domain  is hosted. You can immediately see whether the change took place without waiting for the cache or TTL (Time to Live) that you have configured.
