Macroscopic Internet Topology Data Kit (ITDK)
ITDK 2019-04
For the latest ITDK as well as other historical releases, see
the main ITDK page.
This page describes the ITDK release 2019-04, which consists of
- two related IPv4 router-level topologies,
- 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 Mar 25 to Apr 8, 2019 on 107 Ark monitors located in 43 countries. We also used a subset of the IPv4 Prefix-Probing Traceroute Dataset, which contains traceroutes to a target in every routed BGP prefix. We used traces collected from 30 monitors over the same time period as the Routed /24 dataset above.
