Peering@PCH

Packet Clearing House (www.pch.net) is a non-for-profit research institute which operates public looking-glasses and routing data-collection facilities at many Internet Exchange Points (IXPs) around the world. In order for the data we collect in the looking glasses we operate to be as complete as possible, we attempt to collect peering routes from all participants at each exchange.

In addition our nodes host many anycasted services. We currently host the country-code Top Level Domains (ccTLDs) for more than three dozen countries large and small, a number of gTLDs, several root nameserver instances, and the INOC-DBA (http://www.pch.net/inoc-dba) SIP proxy. The traffic generated by these services is minuscule, but each provides a unique service to the Internet infrastructure community. We make our routing tables available to researchers, the operations community, and the public, in real time at http://lg.pch.net/, and as a historical archive, either by request or at http://www.pch.net/resources/data/routing-tables/ To arrange peering with us, please email peering@pch.net. If you'd like to visit us, in person or contact us for other reasons, please visit our contact information page.

As of May, 2012, PCH is present at the following Internet Exchange Points:
