The Connection dataset describes how each IP range connects to the Internet: the AS number and organization announcing it, the exact BGP route (prefix) it is announced under and the connection type of the network.
It is the offline counterpart of the connection object returned by the Ipregistry API and a building block for traffic classification, fraud scoring and network analytics.

What's inside
The CSV file starts with a header line and contains one record per row, with the following fields:
| Column | Description |
|---|---|
asn | Autonomous System Number announcing the range. |
domain | Website domain of the announcing organization. |
ip_end | Last IP address of the range, inclusive. |
ip_start | First IP address of the range, IPv4 or IPv6. |
name | Name of the announcing organization. |
route | BGP prefix the range is announced under, in CIDR notation. |
type | Connection classification: business, education, government, hosting, isp, or inactive. |
The MMDB variant carries the same data in a memory-mapped binary tree, compatible with the standard MMDB reader libraries available for every major programming language.
What you can build
- Score signups and transactions differently for hosting versus residential origins
- Classify traffic sources in analytics and ad-fraud pipelines
- Map IP ranges to BGP routes for network debugging and research
- Filter datacenter traffic out of audience measurement
