In the Internet’s early days, those wishing to register their own domain name had only a few choices of top-level domain to choose from, such as .com, .net, or .org. Today, users, innovators, and companies can get creative and choose from more than a thousand top-level domains, such as .cool, .deals, and .fun. But should they?

It turns out that not every top-level domain is created equal when it comes to protecting the domain holder’s rights. Depending on where you register your domain, a rival, troll, or officious regulator who doesn’t like what you’re doing with it could wrongly take it away, or could unmask your identity as its owner—even if they are from overseas.

To help make it easier to sort the .best top-level domains from the .rest, EFF and Public Knowledge have gotten together to provide this guide to inform you about your choices. There’s no one best choice, since not every domain faces the same challenges. But with the right information in hand, you’ll be able to make the choice that makes sense for you.
