What does it necessarily means? What is it for? right now my domains are all set to unlock, do I need to lock it? Thanks!
If a domain is unlocked, that means someone else can attempt to move or change the registar's information. Things like the dns hosting, the address of the person registering it, etc. If a domain is locked, any attempt automatically fails. Hope this helps, -drmike
Yes, please lock it now! 'Lock' is very important in order to prevent any attempts of transferring your domain name to another registrar.
