The NLANR group pioneered both wide-scale passive and active Internet measurement projects. NLANR's PMA projects collects both short (90 second) and long (hours or days) traces of Internet traffic, primarily at academic sites. IP addresses in these traces are anonymized and then the traces are publicly available for download and use. As a part of their PMA project, NLANR recently collected the first publicly available OC192/10GigE trace. NLANR's AMP project coordinates active measurements, including round trip time (RTT), packet loss, topology, and throughput (user/event driven), between 150 primarily academic higih-performance computing sites around the world.

The Packet Clearing House provides educational information, including data relevant to network research, to the public. PCH houses an exchange point list and a routing table archive similar to RouteViews.

As the European Internet Registry, RIPE maintains one of the WHOIS databases connecting IP address information with address owners. In addition to this operational responsibility, RIPE also collects time-synchronized active measurements (including delay and IP path) as a part of it's Test Traffic Measurement (TTM) project.

The University of Oregon RouteViews Project collects routing tables from a large number of peers and records them every two hours. RouteViews is useful both for research and operationally as it allows users to see what address prefixes are announced and how those announcements have propagated through the Internet.
