Internet IPv4 Traceroute Dataset Format

ANT Traceroute is collected using Scamper [1] from different locations. The ANT Traceroute pingers are located at multiple locations [2]

Sources

ANT traceroutes are taken from ANT pinger sites (the same locations we use to measure outages and taken censuses), plus selected other sites (currently we add FIU with code “f”).

Destinations

ANT Traceroute updates the target list for probing each quarter.

The specific traceroute targets are taken from a current ANT IPv4 hitlist.

We then intersect it a default-free routing table to get roughly one target per routable prefix.

However, we very split large prefixes to include mutliple targets. Specifically, for prefixes in the routing table that are /20 or longer, we probe one target in each. For prefixes that are /20 or shorter, we split the prefix in to /20s and pick one target for each /20.

Format

Traceroutes are taken with Scamper and written in its native warts (binary) format.

The scamper tool provides tools to convert from scamper to text, JSON and pcap formats.
