If you are getting the response “Current Admin Does Not Match”, this means that the email address you have entered when setting up the transfer does not match the email address listed in the Administrative contact section of the Whois entry for your domain. This address is probably NOT your noip.com account address. It is probably the address you used when initially registering your domain name at your current registrar. To see what the administrative contact email currently is, try looking up the domain at Whois Source.
