Hello i like to transfer my domain.

How can i do that ?

Are there extra costs ?

You can place a domain transfer order at https://www.dynu.com/en-US/ControlPanel/TransferDomainName. Normally you pay a year of registration fee and it extends your domain name for another year.

How do I transfer a domain out? I have a new router and the only service they provide is NO-IP and I've already purchased it but would like to transfer my domain out. Need the code to validate the transfer.

Open a support ticket to request the auth code.
