asked on Subnetting Help
HELP!!!
I have been given an assignment to perform subnetting and although I know the very basics, this has me working like a monkey doing a math problem. I am beyond lost.
The assignment states:
Develop an IPv4 addressing scheme for a remote office using the address 172.36.0.0/23 with a minimum of IP waste for PC networks and exactly the correct number of IP's required between routers. Also to provide a list of available (unused) nets by using the least number of bits for the subnetmask - CIDR.
Router One:
Finance = 11PCs
Account Room = 228 PCs
Router Two:
IT Office = 5 PCs
Web Sales = 58 PCs
Router Three:
Administration = 5 PCs
Business Section = 112 PCs
I have to provide the following for each (finance, IT Office,Administration, Business Section, Account Room, Web Sales) :
Subnetmask being used
NET ID
IPs required
IPs calculated
First available host address
Last available host address
Connections between the firewall router and router :
subnetmask used?
NET ID used?
IP address assigned to firewall connection?
IP address assigned to router 1 on firewall side?
Connections between router 1 & router 2
subnetmask?
NET ID?
IP of router 1?
IP of router 2?
Connections between router 2 & router 3:
subnetmask?
NET ID?
IP of router 2?
IP of router 3?

Got it, THANKS!!! You are a life saver!
The subnetmask for the firewall and all routers is 255.255.255.252 and 172.36.0.0/30 is the netID for the firewall/router 1. The "/30" is confusing to me. This confusion carries over to the departements. For example:
Finance = 172.36.0.32/28... This translates to a host IP range of 172.36.0.33-172.36.0.46 with a net id of 172.36.0.32, a broadcast ID of 172.36.0.47, and a subnet mask of 255.255.255.240?
