What are the different types of IP addresses used at the network layer of the OSI model?

IP addresses are unique identifiers for devices in a network, used at the network layer of the OSI model for data routing. There are different types of IP addresses:

• Public (global) IP addresses — unique on the internet and used to identify devices in the global network.
• Private (local) IP addresses — used within local networks (e.g., 192.168.x.x, 10.x.x.x) and are not routed on the internet.
• Static IP addresses — permanently assigned to a device.
• Dynamic IP addresses — temporarily assigned to devices via DHCP.
• Multicast addresses — intended for transmitting data to a group of devices.
• Broadcast addresses — used for sending packets to all devices in the network.

Each type of IP address serves its purpose in organizing network interaction and routing.
