This is where you get quick access to a lot of IHR data.
This archive is designed for researchers that need large chunks of the IHR database. Each file in the archive consists of:
- 24 hours of data
- for one of the IHR metrics
- and all networks monitored by IHR
All files are available here: https://ihr-archive.iijlab.net/ihr/
The goal of IHR is to advance network research and empower the public with useful information about the characteristics of networks that constitute the Internet. IHR data is provided 'as is,' with all faults, defects, bugs, and errors. IHR does not make any warranty as to the accuracy or completeness of the data.

It's all about data
Daily dumps of AS Hegemony values (a.k.a. Network Dependency) are available here: https://ihr-archive.iijlab.net/ihr/hegemony/ and https://data.bgpkit.com/ihr/
There is two types of files, nammed local and global. Local AS Hegemony represents the dependency of an individual network (Origin AS). Global AS Hegemony represents the centrality of a network in Internet topology. Please see IHR documentation for more details.
Daily dumps of the RPKI and IRR status of all globally reachable prefixes are available here: https://ihr-archive.iijlab.net/ihr/rov/
In this dataset a route correspond to a (prefix, originasn_id) pair. This is a dump of our SQL database. Each line is a row in the database and there is quite a lot of redundant data. Same rows with only different asn_id and hege value refer to the same route (prefix/origin AS pair) but we found multiple transit ASes that are commonly used to access this route. Each row shows the results for a distinct transit AS.

Frequently Asked Questions
I need more data, where is the data for previous years?
In order to save disk space we haven't dumped the entire IHR database here. We are dumping data on request-basis. Feel free to ask for past data at firstname.lastname@example.org.
How can I read these files? What's the file format?
All dumps are Comma Separated Values (CSV) files compressed with lz4. First you should uncompress them to get the CSV file. The first line gives the meaning of each value and each line represents an entry. See also IHR documentation and API to understand the semantics of the values.
These files are too big. I need data for only one (or a few) network and a short time duration?
Then you may be better served by IHR API.
How is the data collected?
