SNS@ISC: ISC's Name Service
SNS@ISC is an infrastructure service for publication of DNS zone data to the global Internet with maximum availability and minimum delay. Customers of SNS@ISC operate their own primary name servers where they manage their DNS zone data, and then SNS@ISC transfers this zone data to one or more of our globally anycast name server clusters. End users will see extremely high availability and short response times when they look up domain names whose DNS zones are served by SNS@ISC.
Available for Enterprise Customers
We welcome commercial enterprises to bring their DNS zones to SNS@ISC; we can host them on our dedicated globally- and regionally-anycasted name servers within multiple commercial ISPs. SNS@ISC can be used either as a DNS zone's only name service, or in conjunction with other in-house or outsourced name services. Please request a quotation.
Available in Bulk
Registrars, dynamic DNS providers, and application service providers (ASPs) are welcome to use the SNS@ISC infrastructure to publish their customer zone data using our multiprovider system of global anycast name servers. Our bulk API allows your back office systems to synchronize directly with ours. Request a quotation.
Available for non-profit / public benefit customers
As part of our community outreach and our own public benefit mission, we offer a public benefit version of SNS@ISC. We are pleased to serve more than 60 top level domains in addition to hundreds of Internet infrastructure, public benefit / non-profit, and partner domains. These DNS zones are served using ISC's global anycast network, the same network that serves F-Root worldwide.
Qualifying organizations, such as non-profits, open source projects, or TLDs may request additional information. For guaranteed response times, service level agreements are available. Due to the legal terms of ISC's non-profit status, we can not extend our public benefit services to political or religious organizations.
Reselling SNS-PB services is prohibited. TLD operators who believe they may qualify as public benefit operations are welcome to contact ISC directly.
SNS@ISC customers must have (in-house or outsourced) their own primary name servers on which they will create and maintain DNS zone data. A customer's primary name servers need not be open to the public, if for security reasons a customer prefers not to bring outside queries into their datacenters. SNS@ISC can provide all, or some, of any of a DNS zone's name service, and so we can be a sole provider (for full outsourcing) or we can be one of many (for vendor diversity).
Since its inception in 1995, ISC has maintained, supported, and published the BIND software system that operates about 80% of the Internet's name servers. In fact, some of ISC's founding employees have supported BIND since 1989. ISC also operates the F-root server, one of the busiest root name servers on the Internet, and the first root name server to deploy anycast technology in multiple continents. No company in the world today has deeper knowledge or expertise about DNS software, technology, and operations than ISC. Through SNS@ISC, we stand ready to make our expertise available to old and new customers who want the best possible DNS zone data publication.
