Registrar-Lock
REGISTRAR-LOCK is a status code that can be set on an Internet domain name by the sponsoring registrar of the domain name.[1][2] This is usually done in order to prevent unauthorized, unwanted or accidental changes to the domain name.
When set, the following actions are prohibited by the domain name registry:
- Modification of the domain name, including:
- Transferring of the domain name
- Deletion of the domain name
- Modification of the domain contact details
Renewal of the domain name is, however, still possible when REGISTRAR-LOCK is set.
Not all Top-level domains (TLDs) support REGISTRAR-LOCK,[3] e.g. .org.uk, and others.
The .ca TLD added support for REGISTRAR-LOCK in October 2010.
RFC 2832, section 6, and RFC 3632, section 2.1, lists the different status codes and their descriptions.
