How to fool an IP address Tracer into believing another IP address?

Need help with Cisco Packet Tracer 6.8.1.3?

• Hey guys, i need some help on my packet tracer 6.8.1.3 CCNA Explorer 1. Any help would be much appreciated You have been given an IP address block of 192.168.23.0/24. Provide for existing networks as well as future growth. 1st subnet, existing student LAN (off of router R2-Central), up to 60 hosts; 2nd subnet, future student LAN, up to 28 hosts; 3rd subnet, existing ISP LAN, up to 12 hosts; 4th subnet, future ISP LAN, up to 6 hosts; 5th subnet, existing WAN, point-to-point link; 6th subnet, future WAN, point-to-point link; 7th subnet, future WAN, point-to-point link. Interface IP addresses: • For the server, configure the second highest usable IP address on the existing ISP LAN subnet. • For R1-ISP's Fa0/0 interface, configure the highest usable IP address on the existing ISP LAN subnet. • For R1-ISP's S0/0/0 interface, configure the highest usable address on the existing WAN subnet. • For R2-Central's S0/0/0 interface, use the lowest usable address on the existing WAN subnet. • For R2-Central's Fa0/0 interface, use the highest usable address on the existing student LAN subnet. • For hosts 1A and 1B, use the first 2 IP addresses (two lowest usable addresses) on the existing student LAN subnet. I need step-by-step instructions on how each ip address is obtained. Thanks, T

  1st subnet 192.168.0.23.0 255.255.255.192 2nd subnet 192.168.0.23.64 255.255.255.224 3rd subnet 192.168.0.23.96 255.255.255.240 4th subnet 192.168.0.23.128 255.255.255.248 5th subnet 192.168.0.23.136 255.255.255.252 6th subnet 192.168.0.23.140 255.255.255.252 7th subnet 192.168.0.23.144 255.255.255.252 • 192.168.23.98 • 192.168.23.97 • 192.168.23.137 • 192.168.23.138 • 192.168.23.1 • 192.168.23.61 for 1A 192.168.23.62 for 1B If you really need more help you can feel free to email me. It would just be a lot of typing to explain how I got those. It would be easier to show, rather than type.
