DNS is essentially a database of IP addresses.  Each IP address is a series of numbers that allow computers to communicate with each other. A website is identified on a server by its IP address. Instead of your visitors having to remember an IP address to type into their browser to access your site, they instead use your domain name. When your domain is entered into their browser, DNS translates it into an IP address because that is what computers understand.Your computer is able to connect to your web hosting and show your website on the browser once the IP address is found.
Name servers. Most registrars provide two or more name servers as part of the registration service. However, a registrant may specify its own authoritative name servers to host a domain's resource records. The registrar's policies govern the number of servers and the type of server information required. Some providers require a hostname and the corresponding IP address or just the hostname, which must be resolvable either in the new domain, or exist elsewhere. Based on traditional requirements (RFC 1034), typically a minimum of two servers is required.
The hierarchy of domains descends from the right to the left label in the name; each label to the left specifies a subdivision, or subdomain of the domain to the right. For example: the label example specifies a node example.com as a subdomain of the com domain, and www is a label to create www.example.com, a subdomain of example.com. Each label may contain from 1 to 63 octets. The empty label is reserved for the root node and when fully qualified is expressed as the empty label terminated by a dot. The full domain name may not exceed a total length of 253 ASCII characters in its textual representation.[6] Thus, when using a single character per label, the limit is 127 levels: 127 characters plus 126 dots have a total length of 253. In practice, some domain registries may have shorter limits.

A domain name registration is simply reserving your website's name for a specified period of time. The two parties involved with a domain registration are generally the user who is registering the domain and the domain registrar. The domain registrant is the user who actually registers the domain name and the domain registrar is the company who helps that user with their domain registration.


Domain names used in works of fiction have often been registered in the DNS, either by their creators or by cybersquatters attempting to profit from it. This phenomenon prompted NBC to purchase the domain name Hornymanatee.com after talk-show host Conan O'Brien spoke the name while ad-libbing on his show. O'Brien subsequently created a website based on the concept and used it as a running gag on the show.[34]
The top ten was rounded out by #8 Ecig.co.uk ($6,613 at DomainLore.co.uk) and two more Sedo sales - #9 Wallace .co at $5,999 and #10 Poianabrasov.ro at $5,632. Sedo went on to sweep 16 of 20 chart entries overall. UnicDomains filled three spots with sales they made on the Above.com Marketplace with their marquee sale of #4 AR.ca ($25,000) joined by #12 (tie) Playground.ca ($5,000) and #20 BlackMarket.ca at $3,500. 
Classic domain extensions work for both options, as well as country specific extensions to build up local relevance. nTLD domain names such as .design, .business, or the eye-catching .nyc are good, .business especially in the case of a website builder package. There's often confusion surrounding the nTLDs, and it's good to know that the TLDs that imply a geographical reference are classified as generic top level domains by Google. For those who opt for website builder packages, it may be worth registering more than one domain extension, especially the classic extensions such as .com, as many users will remember this one better than the nTLDs – if you own the .com version but prefer the nTLD, you can always set up domain forwarding to avoid competition from other websites.

One of the most important decisions in establishing an online presence is choosing a domain name. The right domain name for your website is important, for both your target audience and search engines. Ignore the trends and fads of the day and choose a name that makes sense for your business or subject matter now and will still make sense 10 years from now. Here are 10 tips to help you make a good domain name purchase.
Second-level (or lower-level, depending on the established parent hierarchy) domain names are often created based on the name of a company (e.g., bbc.co.uk), product or service (e.g. hotmail.com). Below these levels, the next domain name component has been used to designate a particular host server. Therefore, ftp.example.com might be an FTP server, www.example.com would be a World Wide Web server, and mail.example.com could be an email server, each intended to perform only the implied function. Modern technology allows multiple physical servers with either different (cf. load balancing) or even identical addresses (cf. anycast) to serve a single hostname or domain name, or multiple domain names to be served by a single computer. The latter is very popular in Web hosting service centers, where service providers host the websites of many organizations on just a few servers.
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.
Keep in mind that these are the highest value cash only sales that have been reported to us in the past week. This column is meant to be an educational tool, not a complete list documenting ALL high value domain sales. Such a list is impossible to produce because many sales are kept private at the insistence of buyers, sellers or both. Our procedure for verifying the accuracy of domain sales reports is available here.
Domain names serve to identify Internet resources, such as computers, networks, and services, with a text-based label that is easier to memorize than the numerical addresses used in the Internet protocols. A domain name may represent entire collections of such resources or individual instances. Individual Internet host computers use domain names as host identifiers, also called host names. The term host name is also used for the leaf labels in the domain name system, usually without further subordinate domain name space. Host names appear as a component in Uniform Resource Locators (URLs) for Internet resources such as web sites (e.g., en.wikipedia.org).
