When the Domain Name System was devised in the 1980s, the domain name space was divided into two main groups of domains. The country code top-level domains (ccTLD) were primarily based on the two-character territory codes of ISO-3166 country abbreviations. In addition, a group of seven generic top-level domains (gTLD) was implemented which represented a set of categories of names and multi-organizations. These were the domains gov, edu, com, mil, org, net, and int.
Linux is the most commonly-used operating system for web hosting in the world, and Linux servers are a popular choice for many websites and applications. It is the industry-standard operating system, and in fact, one of the most popular groups of applications used to back websites is commonly referred to as LAMP, which stands for Linux, Apache (a web server), MySQL (a database), and PHP.
Established back in 1998, LunarPages operates three state-of-the-art data centers. Equipped with multiple GigE fiber connections to the internet backbone, the company built out seismically-braced racks and cabinets, fully-redundant Liebert HVAC cooling systems, a diesel generator that can run for weeks, and a pre-action dry pipe fire suppression system.
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.
Many people may not know that a domain name can be registered at very reasonable prices, sometimes for as little as $.99 per year. In fact, the relatively low cost of domain name registrations can help businesses to register multiple domain names and build a domain name portfolio for use in promotional or brand-protection strategies. The key is to align your brand and relevant keywords to maximize the value your domain name can bring to your existing and future online presence.
Beyond that, Dreamhost is a 5-of-5 hosting company for many reasons. They operate their own control panel, which is convenient and easy to understand.
