Public-benefit DNS infrastructure

Secondary Name Services - Public Benefit (SNS-PB)

SNS-PB is a public-benefit infrastructure service for publication of DNS zone data to the global Internet with maximum availability and minimum delay. Customers of SNS-PB operate their own primary name servers where they manage their DNS zone data, and then SNS-PB 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-PB, and benefit from the features and services offered by the technical staff of Internet Systems Consortium. This is not a commercial service; it is available only to underserved, non-commercial entities, such as the top-level domains of smaller countries or territories.

Benefits of SNS-PB
  • High availability and short response times to domain search queries
  • Increased protection against DOS
  • Shortcut to DNSSEC
  • IPv6-compliant
  • Very low-cost option for qualifying non-profits

For years this service was offered for free; however, ISC can no longer afford to do so. We now ask participants to make an annual contribution to help defray our costs.

Why Internet Systems Consortium?

Internet Systems Consortium has maintained, supported, and published the BIND software system that operates many of the Internet’s name servers.

Besides BIND 9, 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 on multiple continents.

Through SNS-PB, we stand ready to make our expertise available to domain operators who want the best possible DNS zone data publication. No company in the world today has deeper knowledge or expertise about DNS software, technology, and operations than ISC.
