A registrar lock, will prohibit the transfer of the domain to another registrar. This is a security measure that only the account holder can change on individual domains. Not all domains have locks. Typically locks can still be found on .com, .net domains, although you will also need the EPP authorization code to transfer the domain.
Top Level Domains such as .com .net .org
UK domains such as .co.uk
You need to contact your previous host and ask them to change the IPS tag to ENOM. An EPP code is not required.
If you wish to transfer away from Fast2host, login to the client area and select your domain name, Select "more options"
Here you can unlock the domain and generate your EPP code.
