A website domain name, sometimes just called a domain, has different related meanings. Most commonly, a website domain is the name of the website such as www.nepalwebfreelancer.com. Website domains are generally limited to certain letters and numbers. Letters (a-z) and numbers (0-9) are normally used to register the domain. Sometime hyphen (-) is also used to register the domain.
Every website domain ends with top level domain after dot (.) such as .com, .net., .np, .in etc. Second level domain names are often created based on the name of company name, services or person such as www.nepalwebfreelancer.com, www.yahoo.com, www.google.com etc. The registration of these domain names is usually managed by domain name registrars who sell their services to the public. Symbolics.com is the first commercial Internet domain name which was registered on 15 March 1985 by Symbolics Inc.
