Yes, but you will be running into your 10.100.12.x network. The easiest solution might be to move to a 10.100.14.x network with a 255.255.254.0 subnet. Or go bigger, preparing for future growth. Either way, this is non-trivial. Test before you break your network.
Shortest Ever (Incomplete) Subnet Lesson: * A subnet mask defines how big your subnet is. The easiest to understand subnet masks are A (255.0.0.0), B (255.255.0.0) and C (255.255.255.0). * If your current network has a subnet of 255.255.255.0, you are limited to 256 possible host addresses. (For example, 10.100.11.0 through 10.100.11.255). * To make a subnet bigger, you must change the mask. In this example, the _easiest_to_understand_ change is to a subnet of 255.255.0.0. (Which is 65536 host addresses, ie: 10.100.0.0 through 10.100.255.255) * More advanced subnet masks (for example: 255.255.252.0) are very possible. But be prepared for a moderate learning curve. * There are subnet calculators that can help. One is http://www.subnet-calculator.com/ I hope this helps. --Matt Ross Ephrata School District ----- Original Message ----- From: Troy Adkins [mailto:[email protected]] To: NT System Admin Issues [mailto:[email protected]] Sent: Thu, 05 Jan 2012 13:15:29 -0800 Subject: Expanding a subnet > With my lack of IP subnetting knowledge.
