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.

Government (GOV)

Government IPs are assigned to official agencies and entities at local, regional, and national levels. These networks are critical for managing public services, regulatory functions, and general administrative tasks.

Fixed Line ISP (ISP)

Internet Service Providers in this category offer wired broadband connections to homes, offices, and commercial buildings. They are responsible for the fundamental routing of internet traffic and the management of regional network infrastructure.

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.

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.
