Purpose?

• Identify device and to allow communication between them

Dynamic IP

• A dynamic IP is assigned automatically by a device call a DHCP server (usually you router)
• The Ip address may change from time to time, such as when you restart your router

Static IP

• A static Ip is manually assigned and doesn’t change. This is often used for devices that need to be easily reachable, like printers or servers
• Think of your permanent home address-it stays the same all of the time
• If you set up a home web server, you might assign it a static IP so you can always reach the same address

Classes of IP

• IPs in IPv4 are divided into different classes to define the range and purpose of each address
• These classes help organize and allocate IP addresses for different types of networks, from small home networks to large enterprise
• The most common IP classes are Class A,B,C
• There are also Class D, used for multicast
• And Class E, reserved for future use
