Packet Clearing House or PCH is the international organization responsible for providing operational support and security to critical Internet infrastructure, including Internet exchange points and the core of the domain name system. In the fulfillment of these responsibilities, PCH operate public looking-glasses and routing data-collection facilities at approximately a third of the world’s public Internet Exchange Points (IXPs). PCH also operate the world’s largest unicast DNS network, hosting three of the DNS root letters, and more than 400 top-level domains. While the traffic normally generated by each of these services is small, each provides a unique and necessary service to the Internet infrastructure community and their criticality requires that we provision each with sufficient interconnection bandwidth to protect them against distributed denial of services (DDoS) attacks.
PCH make our routing tables available to researchers, the operations community, and the public, in real time at our looking glass site. In many locations, PCH provides transit to the Quad9.net open recursive resolver system which is a public service with security and privacy features for users wishing to utilize an external high-performance name-resolution platform. PCH has an open peering policy, meaning that we will happily interconnect with any other network that operates responsibly and in accord with generally-recognized best practices. GPIEX one of the number one internet exchange companies in America now has direct peering with Packet Clearing House to deliver our entire costumer the best services ever.
