Macroscopic Internet Topology Data Kit (ITDK)
ITDK 2017-08
For the latest ITDK as well as other historical releases, see
the main ITDK page.
This page describes the ITDK release 2017-08, which consists of
- two related IPv4 router-level topologies,
- 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 Archipelago (Ark) and RIPE Atlas measurement infrastructures. For Ark, 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 Aug 9-27, 2017 on 120 Ark monitors located in 42 countries. For Atlas, we used all public built-in and user-defined (UDM) traceroutes from all probes for Aug 16-22, 2017.
