PurposeProvides a non-national alternative to the traditional Top-Level Domain registries. OpenNIC is a user-owned and -controlled Network Information Center.

OpenNIC (also referred to as the OpenNIC Project) is a user-owned and -controlled[1][2] top-level Network Information Center that offers a non-national alternative to traditional top-level domain (TLD) registries such as ICANN.[2] As of January 2017, OpenNIC recognizes and peers all existing ICANN TLDs, for compatibility reasons. However, OpenNIC has not yet evaluated and does not hold a formal position on future ICANN TLDs.[3]

In addition to resolving hostnames in the ICANN root, OpenNIC also resolves hostnames in OpenNIC-operated namespaces, as well as within namespaces with which peering agreements have been established.[3] Some OpenNIC recursive servers (Tier 2 servers) are known for their high speeds and low latency, relative to other more widely used DNS recursors,[4] as well as their anonymizing or no-logging policies.[5][6] Many servers offer DNSCrypt. Tier 2 servers are operated by community volunteers across a multitude of geographic locations.

Like all alternative root DNS systems, OpenNIC-hosted domains are unreachable to the vast majority of Internet users, because they require a non-default configuration in one's DNS resolver.


On June 1, 2000, an article was posted on advocating a democratically governed domain name system.[7] The first OpenNIC servers went into operation July of that year.

OpenNIC TLDs[edit]

OpenNIC namespaces[edit]

These TLDs are currently served by OpenNIC and were constructed with the approval of the OpenNIC community.[8]

Peering agreements[edit]

OpenNIC provides resolution of select other alternative DNS roots.[19]

Name Intended use Date Introduced Notes Peer Authority Status
.bazar free marketplace Emercoin Active
.bit Namecoin systems, websites and services Depeered due to disagreements between the OpenNIC and Namecoin projects.[20] Namecoin Dropped
.coin digital currency and commerce websites Emercoin Active
.emc websites associated with the Emercoin project Emercoin Active
.fur Furries, Furry Fandom and other Anthropormorphic interest websites[21] 2003-11-?[22] Originally an OpenNIC TLD,[22] now operated by FurNIC.[23] FurNIC Active
.ku Kurdish people New Nations Active
.lib From Words Library and Liberty - that is, knowledge and freedom Emercoin Active
.te Tamil Eelam New Nations Active
.ti Tibet New Nations Active
.uu Uyghur people New Nations Active

New Nations[edit]

New Nations provides TLDs for nation-states that are not recognized by the ISO 3166-1 alpha-2 standard, and therefore haven't received their own ccTLD. Currently they provide .ku (Kurdish people), .te (Tamil Eelam), .ti (Tibet), and .uu (Uyghur people).[24]


FurNIC aims to bring a unique identity to Furries, Furry Fandom, and other Anthropomorphic interest websites across the internet. FurNIC and OpenNIC work closely, with .fur (Furry fandom) generally being treated as part of OpenNIC for most purposes, rather than a separate peer entity.[21]


On January 15, 2015, domains registered in Emercoin's blockchain became accessible to all users of OpenNIC DNS.[25] Emercoin DNS supports the domain zones .bazar, .coin, .emc, .lib, .ness and .sky. However, Emercoin DNS records can be registered/maintained from within the Emercoin software, and not as part of OpenNIC's management system.[26]

Technical zones[edit]

OpenNIC operates some special-use TLDs, which are meant for technical or organizational purposes.

Name Intended use Restrictions Notes Status
.opennic.glue[2] Provides hostnames for Tier 1 DNS servers and organizational websites and services.[citation needed] Domains cannot be registered. Domains are granted to each Tier 1 server operator or upon approval of the OpenNIC community. Example: "ns2.opennic.glue" Active
.dns.opennic.glue Provides hostnames for Tier 2 DNS servers on the OpenNIC network.[27] Domains cannot be registered. Domains are automatically created upon the approval of a Tier 2 server. Example: "ns1.any.dns.opennic.glue" Active

Suspended peering[edit]


In July 2019 the OpenNIC community voted 13-2 for dropping support for .bit domains due to them "being used as malware hubs" as a result of their "anonymous nature".[28] A similar proposal was made in December 2018 but it did not reach the voting stage.[29]

Until then OpenNIC resolved .bit (Namecoin) domains through the use of a centralized server which generated a DNS zone from the Namecoin blockchain.[30] Access was provided through a Tier 1 server which bridges the OpenNIC system and Namecoin.[31] Some OpenNIC DNS servers made use of a Spamhaus-maintained blacklist of malicious .bit domains.[32][33][34]
