The Public-Root system is the only reliable technology
that supports universal resolvability and eliminates
domain name conflicts.
The Public-Root is responsible for the operation and
technical management of the Internet's public DNS root
system. This includes a worldwide network of thirteen
master root servers. The Public-Root system maintains
and distributes authoritative root zone files. The thirteen
master root servers propagate the root zone files to
affiliated root systems.
The Internet DNS root server system must be robust
and secured against tampering, abuse or intrusion. Root
operators provide critical infrastructure to the Internet
community and must ensure the security and reliability
of their servers.
The public DNS is tested regularly. These tests address
security issues and include a comprehensive review of
the geographical distribution of root server systems.
This ensures the continued reliability, performance
and response time of our root infrastructure.
Stakeholders in the Public-Root system set standards
by consensus. These standards define the operational
specifications of Public-Root systems. Consideration
is given to hardware selection, host capacity, operating
system, name server software, network connectivity,
redundancy and physical environment. These specifications
form the basis of the contractual obligations binding
root server operators as trustees of the Public-Root.
To be affiliated with the Public-Root operators must
guarantee the stable technical operation of their DNS.
Public-Root is an open inclusive cooperative of roots.
We encourage the private and public sector to us in
provisioning new root servers that support the continued
rapid growth and expansion of the public DNS. Membership
in the Public-Root is open to all organizations willing
to support open access to root infrastructure. Members
must have the required technical skills and resources
to support a root system.
To volunteer your organization or company please contact
the Public-Root Server Advisory Committee (PRSAC).

and testing of root systems in the Public DNS
