Data Center/Web Hosting/Transit (DCH)

This category encompasses data centers, cloud hosting providers, and the transit networks that form the internet's backbone. These IPs are built for high-capacity and maximum uptime, supporting the infrastructure that hosts websites and cloud-based software.

Commercial (COM)

Commercial networks are operated by for-profit businesses ranging from local startups to multinational corporations. These IPs facilitate e-commerce, internal corporate operations, and general business activities aimed at generating revenue.

University/College/School (EDU)

Educational IPs serve universities, colleges, and K-12 schools, providing the backbone for campus-wide connectivity. These networks support a wide array of activities, including academic research, student administration, and classroom instruction.

Search Engine Spider (SES)

Search engine spiders are automated bots and crawlers used by companies like Google or Bing to index the web. These IPs belong to scripts that scan public-facing websites to analyze content and update search results. While they represent automated traffic, they are essential for the discoverability of information on the internet.

Organization (ORG)

Reserved for non-commercial entities, these networks support NGOs, charities, and professional associations. Rather than pursuing profit, these IPs are dedicated to advocacy, public service, and administrative functions.
