The IPv6 Topology Dataset
The IPv6 Topology Dataset contains information useful for studying the IP- and AS-topology of the IPv6 Internet. The focus of this measurement is on discovering topology and not on finding responding destinations. A globally distributed set of Archipelago (Ark) monitors has continuously collected this data since December 12, 2008.
We use scamper to perform ICMP-based traceroutes using the Paris traceroute technique. For each probed path, we collect the IP address, RTT, reply TTL, and ICMP responses for all hops, including intermediate hops.
Each Ark monitor probes all announced IPv6 prefixes (/48 or shorter) once every 48 hours. One probing pass through all announced prefixes is called a cycle. In each cycle, a monitor probes only a single random destination in each prefix. Different monitors probe prefixes in independently-chosen random orders and probe to an independently-chosen random destination in each prefix. Prefixes are randomly ordered in such a way that a given monitor never probes the same prefix within 16 hours across cycle boundaries (a monitor can never re-probe a prefix within the same cycle, by definition).
As of December 2010, 16 of the deployed Ark monitors are probing the 3,972 routed IPv6 prefixes (based on routed prefixes obtained from RouteViews in December 2010). Data Use Restrictions
Acceptable Use Policy for the files of the IPv6 Topology Dataset
- Macroscopic Topology data will not be distributed beyond authorized users.
- I will notify CAIDA of the names and email addresses of any persons (and their respective affiliations) assisting me in research using the macroscopic topology data. This includes graduate students and interns.
- At the end of the research, or semi-annually (which ever is more frequent), a summary of the research and any findings/conclusions will be reported to CAIDA. If any research is described on the WWW, a URL will be provided. This information is primarily used in reports to our funding agencies.
- In so far as possible, research findings and conclusions using the topology data will be published and/or made publicly available
- All users who publish a document (including web pages, and papers) using data from this dataset must provide CAIDA with a copy of the publication and must cite:

Support for the IPv6 Topology Dataset is provided by the National Science Foundation, the US Department of Homeland Security, the WIDE Project, Cisco Systems, and CAIDA Members.
- All users who create a publicly available presentation using data from this dataset must provide CAIDA with a copy of the presentation and must use the full name of the dataset ("The CAIDA IPv6 Topology Dataset") in the presentation. Users are further encouraged, but not required, to include the URL for the dataset (http://www.caida.org/data/active/ipv6_allpref_topology_dataset.xml) in their presentation.
