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.

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.

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.

Library (LIB)

Reserved IP addresses are set aside for future allocation or specialized technical purposes. These IPs are not assigned to the public or commercial sectors for standard use; instead, they are often used for private network testing, protocol development, or emergency contingency planning.
