Macroscopic Internet Topology Data Kit (ITDK)
ITDK 2010-07
For the latest ITDK as well as other historical releases, see
the main ITDK page.
This page describes the ITDK release 2010-07, which consists of
- two related router-level topologies,
- router-to-AS assignments,
- geographic location of each router, and
- DNS lookups of all observed IP addresses.
This ITDK is produced from active measurements conducted on our Archipelago (Ark) measurement infrastructure. We obtained the raw topology by performing traceroutes to randomly-chosen destinations in each routed /24 BGP prefix using 45 Ark monitors located in 26 countries from July 11-26, 2010. We used a subset of the IPv4 Routed /24 Topology Dataset, which is collected continuously.
