Registrars FAQ


OT & E instructions and documentation are available in Become a Registrar.

How do I begin the accreditation process?

The OT&E certification process begins when the registry accepts a registrar's application. Tech Support will send you a welcome package.

If you think you would like to begin the process, please go to the Become a Registrar page.

What do I do after I receive the OT&E welcome package?

The registrar is responsible for developing the client application that will interface with the registry using the EPP protocol. The Registrar Toolkit is available to any interested party that would like to develop Registrar client applications.

A registrar may opt to develop their application to conform to the EPP specification without the use of the Registrar Toolkit. This is acceptable as long as the client is able to pass the OT&E connection test process.

The registry-registrar communication channel will be encrypted. An SSL certificate from an approved certificate authority is required to establish this encrypted channel. The registrar is responsible for acquiring the SSL certificate and developing support for SSL in their client application.

How do I test my client application?

During client development, the registrar will have access to the OT&E environment. In the OT&E environment, the registrar may test the operation of their software to verify the correct handling of EPP commands and their responses.

Operations performed in the OT&E environment will not be charged and will not have any impacts on the live IN Registry. Registrars will continue to have access to the OT&E environment after accreditation, so that they may continue to test their software systems

How do I arrange a time for OT&E testing?

There is no time to schedule any testing as such. When you receive a valid signed SSL Certificate, username and password and confirmation that your IP Range was accepted and whitelisted, you will be able to connect and begin your testing.

What happens after OT&E testing is completed?

Upon successful OT&E connection and you are satisfied that you are able to perform all of the actions required, you should contact the Tech Support team and inform them. Once they have confirmed that they can see you connected in OT&E they will be able to start the process to connect to the live IN Production Registry System.

What key or cert sizes are accepted?

The .IN registry currently utilizes private keys with 2048 bits in length minimum and support up to 4096 bit length.

Security FAQ

How does the Registry control access to the Shared Registry System?

Access to the Shared Registry System is restricted by three mechanisms:

  • Access control to the production SRS is restricted by IP address filters.
  • SSL encryption is required for the communication channels between the Registrar's client system and the OT&E and Production systems.
  • Authentication by means of a username and password is required for session establishment.
