UDAI Expiry - 2014¶
A UDAI is a randomly generated unique identifier that is required to authenticate requests to transfer domain names from one registrar to another. In 2014 DNCL approved a small number of amendments related to UDAIs in the following policies:
These changes came into effect on 5 September 2014 and resulted in the following impact to registrars and registrants:
UDAIs now expire after 30 days
SRS only automatically generates a new UDAI on initial registration only.
More information on how this impacts registrars and the SRS is detailed in the sections below.
Previous UDAI Behaviour¶
A UDAI was previously generated when:
A domain name was registered.
A change in registrant contact details was made.
A domain name was transferred.
A new UDAI was requested.
Under this system a UDAI did not expire which was identified as a security risk.
Current UDAI Behaviour¶
- UDAIs expire:
30 days after generation.
After a domain transfer (and a new one will not be automatically created post transfer).
- New UDAIs will be created:
During initial registration of a domain.
- New UDAIs are NOT created when:
a domain is transferred.
a change in Registrant contact details is made.
SRS and EPP transactions to Generate and Validate UDAI¶
Registrars can validate a UDAI using either of the following transactions:
- SRS UDAIValidQry
( see srs-transactions - UDAIValidQry )
- EPP domain:info
( see epp-commands - domain:info )
Registrars can generate a new UDAI using either of the following transactions:
