Top-level domains are the letters after the dot, like .com, .uk, .biz, or .mobi. Since 2003, hundreds of new top-level domains have come onto the market, and there has never been more choice for domain name registrants. But apart from choosing a name that sounds right and is easy to remember, a domain name registrant should also consider the policies of the registry that operates the domain, and those of the registrar that sells it to them.
avoid registering in a top-level domain that offers special rights and procedures to brand owners, that could result in your domain name being wrongly taken away or could embroil you in dispute settlement proceedings.
we draw attention to the policies of registries Donuts and Radix that have established private deals with the Motion Picture Association of America (MPAA) appointing it as a "trusted notifier" to initiate a registry-level take down of websites that it claims are engaged in extensive copyright infringement.
