Every website on the internet has a unique IP address assigned to it, made up of a series of numbers. These numbers tell the domain name system (DNS) to locate the corresponding website. As we are humans and not computers, IP addresses are difficult to remember and so words are used instead. These words are known as the domain or URL. The DNS looks at the domain name and translates it into an IP address.
^ Mockapetris, P.V. (November 1987). "Domain names - concepts and facilities" (HTML). IETF Documents. IETF. doi:10.17487/RFC1034. Retrieved 24 July 2017. Relative names are either taken relative to a well known origin, or to a list of domains used as a search list. Relative names appear mostly at the user interface, where their interpretation varies from implementation to implementation, and in master files, where they are relative to a single origin domain name. The most common interpretation uses the root "." as either the single origin or as one of the members of the search list, so a multi-label relative name is often one where the trailing dot has been omitted to save typing.
The target audience is just as varied as the contents of the Domain Guide, as it’s made up of small and medium-sized businesses as well as website operators, domain traders, and inquisitive readers.

A short, one-word name (ex. cat.com), and especially .com domains, will be pricy because simple titles have a lot of potential uses, meaning people probably already check them out on their own. If you are going after a registered .com domain, you will have to contact the current owner, and even then, prices could be high for misspellings and multiple word domains. In the past years, companies and individuals have settled for bizarre names, misspellings, and old tricks like adding “the” or “my” to the front; note, however, that this will also reduce domain performance.

If your purpose in buying a trademarked term as a domain name is to try to confuse people, you’re opening yourself up to having a complaint filed against you and having to give up the domain name. Even if you’re not trying to create confusion, you’re likely to face some legal challenges by buying trademarked terms in your domain name. To be safe, you can search for U.S. trademarks at www.uspto.gov and make sure no one owns a trademark on the name you are considering.

Yes. We recommend buying not only your domain name with your favorite extension (eg. .com), but also additional, alternative domain extensions (eg. .net, .info, etc). The reason is simple. Having more than one domain extension strengthens your online identity, secures your brand name and improves your online presence. Buying more than one domain extension also protects you from your competitors registering your additional extensions and enticing away your customers.
When looking up a bare name in DNS, the network stack will add the search domains to it to form fully qualified domain names, and look up those as well.[8] For example, if the domain search list contains "wikipedia.org", typing "en" in the browser will direct the user to "en.wikipedia.org". Some ISPs add their own search domains via DHCP settings, similar to how they add DNS servers and other networking information; if this is undesired, the user can change this setting to ".local".
