Overview
Core Mission
Packet Clearing House (PCH) is an international organization committed to providing essential operational support and security for critical Internet infrastructure. Its primary focus lies in bolstering the resilience and accessibility of Internet exchange points (IXPs) and the foundational Domain Name System (DNS).
Genesis and Foundation
Established in 1994 by Chris Alan and Mark Kent, PCH emerged from the need for more efficient regional and local network interconnection solutions, particularly for the West Coast of the United States. It has since evolved into a global leader advocating for neutral, independent network interconnection.
Areas of Expertise
Beyond its core infrastructure support, PCH actively engages in crucial areas such as cybersecurity coordination, the development of regulatory policy frameworks for telecommunications, and the complex field of Internet governance. This multifaceted approach ensures a holistic strategy for a stable and secure global Internet.
Key Initiatives
Internet Exchange Points (IXPs)
PCH plays a pivotal role in the global IXP ecosystem, contributing to the development and operational support of nearly half of the world's approximately 700 IXPs. It maintains the definitive index of these critical interconnection hubs, with historical data dating back to 1994.
Domain Name System (DNS) Infrastructure
The organization operates one of the world's most extensive anycast DNS server platforms. This includes managing critical components such as two root nameservers, supporting over 400 top-level domains (TLDs) across more than 130 countries, and hosting the widely used Quad9 recursive resolver.
DNS Security Extensions (DNSSEC)
PCH is responsible for the unique FIPS 140-2 Level 4 global TLD DNSSEC key management and signing infrastructure. This highly secure operation is distributed across facilities located in Singapore, Zurich, and San Jose, California, ensuring the integrity of DNS resolution.
Network Research and Data Collection
With a presence in over 130 countries, PCH actively implements initiatives for collecting network research data. This data underpins its extensive research into Internet architecture and policy implications.
