Macroscopic Internet Topology Data Kit (ITDK)
ITDK 2019-01
For the latest ITDK as well as other historical releases, see
the main ITDK page.
This page describes the ITDK release 2019-01, which consists of
- two related IPv4 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 was produced from traceroutes conducted on the Archipelago (Ark) measurement infrastructure. We used a subset of the IPv4 Routed /24 Topology Dataset, which contains traceroutes to randomly-chosen destinations in each routed /24 BGP prefix. We used traces collected Dec 26, 2018 to Jan 10, 2019 on 101 Ark monitors located in 44 countries.
