Macroscopic Internet Topology Data Kit (ITDK)
ITDK 2017-02
For the latest ITDK as well as other historical releases, see
the main ITDK page.
This page describes the ITDK release 2017-02, 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. For the 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 121 Ark monitors located in 42 countries on Jan 22 to Feb 7, 2017.
