  1. Network Layer IP Address

  2. Given an IP Address and a Network Mask Determine : • 1st IP Address (Network ID) • 1st Assignable Address • Last Assignable Address • Last IP Address (Broadcast) • Number of Devices • 2(32-n) - 2

  3. Given an IP Address and a Network Mask (/n) Determine : • 1st IP Address (Network ID) • Find the nth bit in the IP address. All bits to the left stay the same; all bits to the right go to 0. • 1st Assignable Address • Add 1 to the last (4th) decimal of the Network ID. • Last Assignable Address • Subtract 1 from the last (4th) decimal of the Broadcast. • Last IP Address (Broadcast) • Find the nth bit in the IP address. All bits to the left stay the same; all bits to the right go to 1. • Number of Devices • 2(32-n)– 2 = use calculator.

  4. 10.252.49.52 / 24 Determine : • 1st IP Address (Network ID) • 1st Assignable Address • Last Assignable Address • Last IP Address (Broadcast) • Number of Devices • 2(32-n) - 2
