How are IP addresses allocated?

How are IP addresses allocated?

IP addresses are distributed in a hierarchical system. As the operator of Internet Assigned Numbers Authority (IANA) functions, ICANN allocates IP address blocks to the five Regional Internet Registries (RIRs) around the world. (The “regions” of the Regional Internet Registries are roughly continental in size.)

What are the 3 private IP address ranges?

The Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of the IP address space for private internets:

• 10.0. 0.0 – 10.255. 255.255 (10.0. 0.0/8 prefix)
• 172.16. 0.0 – 172.31. 255.255 (172.16. 0.0/12 prefix)
• 192.168. 0.0 – 192.168. 255.255 (192.168. 0.0/16 prefix)

What is the hierarchy of IP address?

Instead of treating the entire 32 bits as a unique identifier, one part of the IP address is designated as the network address (or network ID) and the other part as a node address (or host ID), giving it a layered, hierarchical structure. The network address uniquely identifies each network.
