Today, on May 17th 2011, the SIDN (.nl registry) has changed the transfer procedure. Transfers for .nl domain names will now happen slightly different than before.
The new transfer procedure will drop this 5 days grace period, which used to start once the transfer had been launched. The rest of the procedure remains the same. So the owner still needs to get the token for the name from his current registrar and he needs to send it to the new registrar. The new registrar will then initiate the transfer, which will now be completed almost immediately instead of after 5 days.
The fact that the registration period starts over again after a .nl transfer doesn’t change. So the best thing to do, is still to transfer the .nl domain name as closely to its expiration date as possible, in order to loose a minimum of the registration period.
