Hostwinds remains a user-friendly option for registration and hosting, even if you're transferring from another service. It lists out all the extensions to create your domain name with prices to register, transfer, or renew for each extension, unlike some services that bury these within the website. You simply enter the domain name you want and check the availability, and can theoretically get going in a few clicks (if it's available or taken). It will then tell you if it is available or taken. They've also got live chat, email, and phone technical support before purchase too, which is rather rare.
Domain names disappear extremely fast. Many people claim that all the good domain names are gone. I doubt that — but it is probably true that most good domain names that are descriptive of products and services have been taken. If you want a domain name for your site, I suggest you act now, or face the anguish of having lost that name later. After all, US$10 (more or less) for a year's ownership of the name is rather cheap when you realise that you're securing a good name for your website.
A fictitious domain name is a domain name used in a work of fiction or popular culture to refer to a domain that does not actually exist, often with invalid or unofficial top-level domains such as ".web", a usage exactly analogous to the dummy 555 telephone number prefix used in film and other media. The canonical fictitious domain name is "example.com", specifically set aside by IANA in RFC 2606 for such use, along with the .example TLD.
Premium domains (also known as aftermarket or pre-registered domains) are short domains, often just one word or even just 3-5 letters. Most of them have a .com extension but many premium domains end with .org, .net, and .biz. These domains include common words and are generally the most memorable. Because companies value short domains that match their company name or products, these domains are typically the most desirable. Additionally, certain domains sold by different registries are considered premium and therefore have a higher price point. In some cases, the renewal costs of these higher-priced domains are also quite expensive. Some high-priced premium domains, though, renew at a regular (lower cost) rate, giving you a better value in the long term. Make sure to research the overall cost of the domain plus renewal to find the right domain for your budget. You can browse Namecheap's premium domains in our Marketplace.
