Public Services Network domain name system obligations

Obligations relating to the Public Services Network (PSN) domain name system (DNS).



These documents place obligations on domain name services for the PSN, which come into force immediately. There are separate sets of obligations for:

  • the single PSN authoritative nameserver service
  • each PSN DNS resolver service

The obligations are designed to maximise the use of commodity DNS services whilst maintaining the security necessary for PSN.
