3.0 IP Connectivity

IP Connectivity refers to the ability of different devices to communicate with each other using IP (Internet Protocol) addresses. IP connectivity allows devices to transmit and receive data packets between networks, enabling communication between devices such as computers, servers, printers, and routers.

For IP connectivity to be established, several conditions must be met:

• 1. The devices must be assigned unique IP addresses, either statically or dynamically.

• 2. The devices must be connected to a network, such as a LAN (Local Area Network) or WAN (Wide Area Network).

• 3. The devices must have compatible network protocols, such as TCP/IP (Transmission Control Protocol/Internet Protocol).

• 4. The devices must have proper routing and subnetting configurations, allowing them to send and receive data packets.

• 5. The devices must have proper security measures, such as firewalls, in place to protect against unauthorized access.
