Alternative DNS root
The Internet uses the Domain Name System (DNS) to associate numeric computer IP addresses with human readable names. The top level of the domain name hierarchy, the DNS root, contains the top-level domains that appear as the suffixes of all Internet domain names. The most widely used (and first) DNS root is administered by the Internet Corporation for Assigned Names and Numbers (ICANN). In addition, several organizations operate alternative DNS roots, often referred to as alt roots. These alternative domain name systems operate their own root nameservers and administer their own specific name spaces consisting of custom top-level domains.
The DNS root zone consists of pointers to the authoritative domain name servers for all TLDs (top-level domains). The root zone is hosted on a collection of root servers operated by several organizations around the world that all use a specific, approved list of domains that is managed by ICANN. By contrast, alternative roots typically include pointers to all of the TLD servers for domains delegated by ICANN, as well as name servers for other, custom top-level domains that are not sanctioned by ICANN. Some alternate roots are operated by the organizations that manage these alternative TLDs.
Zach Bastick proposes that alternative DNS roots have allowed for more democratic control of the Internet:
"The implementation of alternative gTLDs predates any significant debate on name space extension by official actors, and this exemplifies how democratising the DNS alters the pace of developing Internet policy, the nature of decisions that justify that policy development, and political dynamics and user autonomy in the network infrastructure." (p.103)
eDNS (Enhanced Domain Name Service) was founded by a coalition of ISPs led by Karl Denninger of the Chicago-area MCSNet. It ceased operation in 1998. It served the following domains: biz (general business use), corp (corporations), fam (for and about family), k12 (for and about children), npo (non-profit organizations), per (personal domains), web (web-based sites, Web pages).
One of the notable challengers to ICANN's control of the DNS namespace was Open RSC (Open Root Server Confederation), a group that grew out of private discussions and developed into a public mailing list. It grew large enough that the group decided to submit an application to the United States government to run the DNS.
ORSC publishes a root zone containing additional top level domains not found in the ICANN root zone.
