Internet data remains one of the basic components of computer science network research. Despite its necessity, available data is limited by legal, social, and technical constraints on its collection and distribution. Thus, optimal distribution of knowledge about available data is a valuable service to the research community. To this end, CAIDA has developed the Internet Measurement Data Catalog to:

• facilitate searching for and sharing of data among researchers
• enhance documentation of datasets via a public annotation system
• advance network science by promoting reproducible research
