Fields recorded from the file

These are literal field names and values. A timestamp or counter is shown without assigning an update schedule to it.

The parser recorded no publisher version or timestamp field for this file.

No selected facet values were collected by this measurement.

Reproduce the count

Save the linked source as provider-file, download the Python measurement script, then run:

python3 ip-ranges-measure.py provider-file

The result includes counts, fields and a hash. A different hash means you measured different bytes. Counts retain overlapping prefixes and repeated address space under different prefix lengths. Full counting method.

ASN reference records

Holder names were read from RIPEstat on the dates below. These are separately selected reference records, not a mapping of every prefix to its origin ASN. A listed holder may differ from the provider named on this page.

Interpreting this snapshot

Where is the GitHub IP range file?

The selected snapshot was downloaded from https://api.github.com/meta. The source and documentation links above let you inspect the publisher's current data and scope.

What does a matching prefix establish?

A match means an address falls inside a prefix in this selected file. The measurement does not establish the identity of a requester, a device location or ownership of every address. Check the publisher’s documentation before applying access rules.

How often is this file updated?

This record measures the file fetched at 2026-09-21T19:35:32.479931+00:00. Publisher fields are reproduced as recorded, without inferring a future update schedule. Download the current source and compare hashes to check for a change.
