IP Addresses

•  IPv4
• Class A, Class B, Class C, Class D, and Class E, IP addresses
• Introduction to IPv6
• Subnets
• Routed protocols and Routing Protocols (Deification, Similarity, Differences and examples)

Practical Portion

• Installing and Configuring Modem
• DSL Configuration

• Creating Cross Cable
• Creating Rollover Cable
• Basic Commands for Troubleshooting
• Ping, ipconfig / all, ipconfig / renew, ipconfig / release, trace route,

 Case Study:

•  Installing network simulator (packet Tracer)
• Creating simple network scenarios
• Configuring PC’s with IP addresses subnet mask and gateway
• Configuring switches by giving name to switches and management IP addresses
• Connection PCs to switch and then ping each other` that they are working properly.
