Summary
GitHub
business hosting developer cloud
GITHUB is the autonomous system operated by GitHub, Inc.
What it's used for
- The address space carries corporate infrastructure for a developer platform, with netnames
GITHUandGITHUB-NET4-1registered to GitHub, Inc. - The AS announces 9,216 IPv4 addresses across 6 prefixes and 2 IPv6 prefixes, while maintaining 48 observed neighbours, indicating a business network with significant peering relationships rather than a transit provider.
Notable
- All registrants in the evidence pack are GitHub, Inc., fully agreeing with the AS announcer.
- The address inventory is finely subdivided into multiple /20, /21, /22, and /23 blocks, consistent with internal corporate estate segmentation for a large-scale service provider.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 445 networks and 1,817 prefixes, as published 2026-10-27. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
1 IC3 indicators addresses in this network appear in FBI IC3 cybersecurity advisories.
| Prefix | Advisory | Published |
|---|---|---|
140.82.114.4 | #StopRansomware: SafePay Ransomware | 2026-10-20 |
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
