Automatic registrar updates

DNScaster sports the ability to make automated updates at your domain registrar on your behalf. Two key types of updates are supported: delegation updates and glue record updates.

Delegation updates

The list of nameserver names that a domain is pointed to is called its delegation. It’s the list of nameservers that are responsible for DNS queries for that particular domain. For instance, might be pointed (delegated) to and

Typically this is a set and forget operation. It is usually required when changing DNS providers, such as migrating into DNScaster. It would also need to be revisited if adding or removing a nameserver.

To make migration easier, DNScaster can perform these updates for you on supported registrars. Any domain and registrar may be used with DNScaster. If the registrar doesn’t support automatic updates, delegation updates will merely need to be performed manually. In all cases DNScaster will show you the current delegation status to help identify if any updates are needed.

Delegation updates may be enabled or disabled on a per-domain basis.

When enabled, DNScaster will also automatically update domain delegations anytime a nameserver name is added, removed, or renamed.

Glue record updates

Glue records, also called nameserver registrations, connect a nameserver name, such as, to its IP addresses (both IPv4 and IPv6).

Glue records are only required for domains used to create vanity names. For instance, glue updates would be needed for when the vanity names and have been added.

When glue records are required, DNScaster will automatically manage these glue record updates for you. Automatic updates will be performed anytime a nameserver name or instance is added, removed, or experiences an IP change.

Glue record updates must be enabled for domains used as a base domain for a vanity name. Accordingly, these vanity-enabled domains must use a supported registrar. All other domains may be registered with any registrar.
