Moving from class C to class B on our private network

[wowhead]

Anyone done this? What's the easiest way to go about this? I was hoping that I could create a new VLAN on our Cisco 3560s (using the same subnet but a different mask) & utilize InterVLAN routing until I could get around to changing all the static numbered hosts. I thought I was being slick & that avoiding a complete renumber

Since the switch won't let me do what I want I'm having to rethink this and so I thought I'd bounce this idea off of you & see what happens next.

I've made a discovery today. I have a dual boot system (XP and Vista). I have the ability to configure a %VLANID% field in my NIC properties and now my workstation can communicate across the swtiches & out to the Internet on my new VLAN. However, I've take one step backward too. I can no longer communicate to the native VLAN. Ideas?
