The Routing Report first saw light of day on the 23rd February 1999. The Internet was seeing explosive commercial growth then, and no one was closely examining the rapid changes in the global Internet routing table. There were no published reports, and the CIDR Report was then used as a marketing tool by ISPs wishing to show off how "big" they were. With the encouragement of APNIC and many colleagues in the industry, I started producing the daily Routing Report, taking a more detailed look at the state of the Internet routing table by each Regional Internet Registry.

The Routing Report repository on this site is focused mainly on the Global Research and Education network infrastructure, and aims to assist the R&E community with improving routing announcements made to the global Internet. A detailed explanation of the daily routing report documents how the report assists networks operators, and what each field means. The technical discussion of what goes on behind the scenes to bring this report to this site is also available.

NSRC's validator is available at We make this available for network operators who wish to check the validation status of prefixes being announced to the Internet..

The current RPKI data obtained from NSRC's validator cache is provided here for reference. Note that NSRC's validator uses TALs from AfriNIC, APNIC, ARIN, LACNIC, and RIPE NCC, as well as APNIC's and LACNIC's AS0 TAL.
