Crawlers & bots
Search, ads, SEO, and social crawlers with published identity or ranges.
AI platforms
LLM and AI product vendors that publish crawler, user-fetch, or API egress IP guidance.
CDN / edge
Official allowlist-style IP lists for edge and caching networks.
Cloud infrastructure
Hyperscaler and cloud provider range publications.
Developer & SaaS

Education
Autonomous system numbers commonly seen in BGP for K-12 networks and higher education
How we list sources: we link vendor-published feeds and documentation where they exist. Entries labeled maintained are aggregated or deduplicated here for tooling - we do not treat BGP scrapes or third-party ASN dumps as authoritative “official” ranges.
Education: separate community-maintained ASN lists for K-12 districts and universities (BGP context only - see those pages for caveats).
