Alternative Root Server
Alternative Root Servers or the Alternative Domain Servers are a kind of practice which is in effect as a part to create an Internet outside the official Internet. The control of the official Internet is mostly in the hands of the Internet Corporation for Assigned Names and Numbers (ICANN) which is a government sanction private organization of the United States. ICANN has full control over the ‘root’ server, which is nothing but a file on a computer which is kept at Herndon, Virginia. This file works as the official list of domain names on the Internet. 
How do the Alternative Root Servers operate?
The Alternative root server operates by reproducing the information that is available in the root server. It reproduces the entire information in the root server and adds some extra unsanctioned addresses to the list. When the Internet users reconfigure their browsers with a view to point towards an alternate root server, it creates an entire new network. Through this new network one can also access the Internet under Internet Corporation for Assigned Names and Numbers (ICANN). 
History of Alternative Root Servers
The Alternative Root Servers have been in existence since the year 1995. It came into existence especially when several groups of Internet users found out that they didn’t had any more choices available than the .com, .org and so on. These users came forward with a way through which they could put to use their technical knowledge about using the existing namespace. The regulation of the Alternative Root Servers was handed to the Internet Corporation for Assigned Names and Numbers (ICANN). In the year 2001, ICANN came up with seven new Top level Domains or TLDs. 
The number of Alternative Root Servers in existence
Currently, there are 15 Alternative Root Servers in existence. The operators of these servers range from the non-commercial collectives such as the OpenNIC or the outlawed libertarian free marketers. Of these, the Name.Space co-operates with the two shared alternative root networks which are known as the PacificRoot and the Open Root Server Confederation or the ORSC. The data doesn’t come easily on the alternate namespaces. There is also a lot of difficulty on the use of data of alternate namespaces as it is far from being conclusive. The number of people using the Alternative Root Servers ranges from 5% - 30%. In technical terms, there is no set limit for the amount of TLDs that can operate simultaneously. 
Alternative Root server and ICANN
The Internet Corporation for Assigned Names and Numbers (ICANN) governs the Alternative Root Server. It maintains a well as operates the Alternative Root Server from Virginia with the help of the Network Solutions or NSI.
