Macroscopic Internet Topology Data Kit (ITDK)
ITDK 2015-08
For the latest ITDK as well as other historical releases, see
the main ITDK page.
This page describes the ITDK release 2015-08, which consists of
- two related router-level topologies,
- an IPv6 router-level topology,
- 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. For the IPv4 router-level topology, we used a subset of the IPv4 Routed /24 Topology Dataset, which is collected continuously. Specifically, we obtained the raw IPv4 topology by performing traceroutes to randomly-chosen destinations in each routed /24 BGP prefix using 94 Ark monitors located in 36 countries on Aug 16-31, 2015. For the IPv6 router-level topology, we used a subset of the IPv6 Topology Dataset for the same time period (to line up with the IPv4 data above). We obtained raw IPv6 topology data from 26 monitors located in 15 countries.
