Bogon IP ranges, free with an account.

The schema and metadata are in the docs. It is published as CSVGZ and MMDB. For each range and the RFC that reserves it, see Bogon IP address ranges.

One call gets you the current Bogon IP build. Every official client wraps it three ways: straight to disk, a time-limited link you hand to your own runner, or bytes in memory, and checksums() returns the published digests to verify it against.

download()

Streams the current build to a file, which lands only once the whole transfer has arrived, so a failed one never leaves a truncated file behind.

downloadUrl()

The time-limited link the API redirects to, for your own downloader, a job runner or a CDN pull.

downloadBytes()

The build in memory, for a small database or a pipeline that never touches a filesystem.

metadata()

Row count, file sizes and when the build last updated. Poll it and fetch only when a new one has landed.

checksums()

The md5, sha1, sha256 and sha512 digests of one file, to verify it once it lands.

Free with an account, and the file is yours: teams join Bogon IP against the traffic, logs and routing data they already hold, inside their own infrastructure.
