IP Addressing Schema for ?
-
There are 10 computers in the building, five on each floor. You are required to give all of them Internet access using only one DSL or high-bandwidth connection. Hence there will only be one entry point for internet in the building. The connection will be shared across ten computers. Also, 2 floors must be on different subnets. How IP addressing schemes should be? Right now, I've decided to use one of the 3 private address blocks reserved for private networks. (192.168.x.x; 172.16.x.x; 10.0.0.0) So, I use the 192.168.0.0 address space with its designated sub-net mask of 16-bits (255.255.0.0). By the way, I'm planning to use wi-fi access. Any ideas/ suggestions?

Answer:
I would use 192.168.1.x/24 on the first subnet and 192.168.2.x/24 for the second. Just because it's easy to manage, no subnet calculator needed :). You'll need DHCP server on each subnet unless you're setting up each host manually. So you now got two vlans and one Internet connection, so easy! =)

First off, why would you use a class B subnet? A class B subnet would allow up to approx. 65,000 IP addresses. This is way overkill for 10 computers. What i'd use is a modified custom class C subnet. Something that would take about 16 IP addresses would work best. So a subnet like 255.255.255.240. This would allow 16-2 workstations. The minus 2 is the Broadcast IP and Host IP of that subnet. As for Wi-fi you would want to do a wireless assessment to see where to place the WAP's. Each WAP does take at most 25-30 connections at a time, but depending on how large the organization is a large deal also. I dont see any reason to use 2 seperate subnets here unless for security reasons. Since the subnet i gave you allows 16 addresses, then your first block would go from 192.168.1.0-16. The next would start at 192.168.17-32. And each block would increase by 16. Use an IP calculator to check my math is right (using my brain only here) so i could be a little wrong. Just downlaod an IP calculator and i think you'll be fine. Good luck
