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 184.108.40.206/23 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.
Finance = 11PCs
Account Room = 228 PCs
IT Office = 5 PCs
Web Sales = 58 PCs
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
First available host address
Last available host address
Connections between the firewall router and router :
NET ID used?
IP address assigned to firewall connection?
IP address assigned to router 1 on firewall side?
Connections between router 1 & router 2
IP of router 1?
IP of router 2?
Connections between router 2 & router 3:
IP of router 2?
IP of router 3?
The subnetmask for the firewall and all routers is 255.255.255.252 and 220.127.116.11/30 is the netID for the firewall/router 1. The "/30" is confusing to me. This confusion carries over to the departements. For example:
Finance = 18.104.22.168/28... This translates to a host IP range of 22.214.171.124-126.96.36.199 with a net id of 188.8.131.52, a broadcast ID of 184.108.40.206, and a subnet mask of 255.255.255.240?
