Guys, I could use some help here.I'm pretty new to routing. I have a Class C IP address block that I want to subnet. In reading through some documentation, If I want to split it into 2 subnets, the netmask would be 255.255.255.128, and each subnet will have 126 usable addresses: #1: 10.0.0.0 - Network 10.0.0.1-126 - Useable IP's 10.0.0.127 - Broadcast #2: 10.0.0.128 - Network 10.0.0.129-254 - Useable IP's 10.0.0.255 - Broadcast I only have a need for 2 addresses on one subnet, which I can accomplish with netmask 255.255.255.252 - this would give me 2 usable IP addresses: 10.0.0.0 - Network 10.0.0.1-2 - Useable IP's 10.0.0.3 - Broadcast However, this would split the Class C block into 64 subnets, with only 128 usable IP addresses. (2 per subnet, the rest would be reserved for broadcast and network IP's). My question is: How can I split a Class C block of IP addresses like so - Network #1: NetIP: 10.0.0.0 Usable IP's: 10.0.0.1-2 Broadcast: 10.0.0.3 Network #2: NetIP: 10.0.0.4 Useable IP's: 10.0.0.5-254 Broadcast: 10.0.0.255 Is this even possible? What other alternatives would I have besides subnetting, if I want both the above networks separately routable on different interface cards? Note: (Assume the 10.0.0.x numbers are 'real' routable IP's) Thanks for any input!! -Lucas
