Alternative DNS root

The Internet uses the Domain Name System (DNS) to associate the names of computers with their numeric IP addresses and with other information. 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 official 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 Internet Architecture Board has spoken out strongly against alternate roots in RFC 2826.[1]

[edit] Description

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.

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.

Alternative DNS roots may be characterized as three groups:[citation needed] those run for idealistic or ideological reasons, those run as profit-making enterprises, and those run internally by an organization for its own use.

While technically trivial to set up, the maintenance of a reliable root server network is a serious undertaking.[citation needed] In order for the system to be effective, multiple servers must be run continuously without interruption in geographically diverse locations.

During the dot-com boom, some alternate root providers[who?] believed that there were substantial profits to be made from providing alternative top-level domains.[citation needed]

Only a small portion of Internet service providers actually use any of the domains served by alternate root operators, generally supporting only ICANN-sanctioned root servers. This has led to the commercial failure of several alternative DNS root providers.[citation needed]

A top-level domain with the name biz, created by Pacific Root was in operation before ICANN approved the official domain biz, operated by Neulevel. For some time after the creation of the official domain, several alternate roots continued to resolve the name to Pacific Root's servers rather than Neulevel's. Therefore, some domain names existed in different roots and pointed to different IP addresses. The possibility of such conflicts, and their potential for destabilizing the Internet, is the main source of controversy surrounding alternate roots. Many of the alternate roots try to coordinate with each other, but many do not, and no conflict resolution processes exist between them.

[edit] List of alternative roots and their domains

This section lists the known alternate DNS roots, and for each root, lists the TLDs carried in addition to the ICANN-sanctioned gTLDs and ccTLDs.

[edit] Public-Root

  • Public-Root resolves multiple kinds of TLDs globally. It is created to offer an alternative, open DNS infrastructure with its own 13 root servers around the world.
  • Administrated by INAIC
  • Open for registration of new TLDs through an approved registrar, such as GQNET

[edit] 42registry

42registry

  • Domains like .42

This TLD server will probably start to work with OpenNIC soon.[2]

  • .ti Internet for Tibet
  • .te Internet for Tamil Eelam
  • .ku Internet for Kurdish People

[edit] UnifiedRoot

UnifiedRoot

  • UnifiedRoot enables all existing TLDs and allows new TLDs to be registered at a cost of €50,000 each (plus annual maintenance fees of €12,500).

UnifiedRoot offers a downloadable tool to modify the name server configuration on Windows. UnifiedRoot have also made agreements with ISPs and telcos to enable access to the provided TLDs.[not in citation given] UnifiedRoot supports internationalized domain names (IDN) for top level domains (TLDs).

  • Resolves too many zones to be listed here.

MobileTLD

  • MobileTLD claims to resolve domains for mobile devices.

[edit] NameCoin P2P DNS

NameCoin TLDs are not managed by any single organization. Every NameCoin peer has a database copy. Forced work is used to prevent squatting and other kinds of abuse. NameCoin software allows domain registration under any TLD, but only .bit TLD is currently supported. Users may either use alternative DNS, DNS suffix, gateway, browser plugin or install NameCoin software and gain independent authentic view of namespace. In the latter case NameCoin domains can't be disabled or transferred by an authority.

[edit] Open Root Server Network

ORSN was shut down 31 December 2008

  • Used to be a mirror of the ICANN root.

[edit] Open RSC

Open RSC

One of the notable challengers to ICANN's control of the DNS namespace was Open RSC, a group which grew out of private discussions and developed into a public mailing list which grew large enough that the group decided to submit an application to the US government to run the DNS.[3]

The organization posted bylaws and articles of incorporation outlining ORSC's position following extensive public discussion regarding the manner in which the DNS was operated.[4][5]

ICANN chairwoman Esther Dyson acknowledged adopting features such as membership from ORSC in her response to the US Department of Commerce.[6]

ORSC publishes a root zone containing additional top level domains not found in the official root zone.

  • per — personal pages
  • etc — anything
  • web — for the web
  • shop — online shops
  • pickle — just a general funny name
  • sco — for Scottish culture
  • mail - a tld for email - to reduce spam and clearly identify email servers.
