Too many IPs on subnet
Posted on 2011-05-06
Hardware/software used: Windows Server 2008 Ent R2. HP procurve switches (1800).
I am at the point where my network at work is starting to have too many devices that are requesting for IPs from DHCP server (windows server 2008 R2). Due to the cabling, I can't really place a router for a different segment of the building, and also would rather not separate them such that I can't directly reach the client computer from the server if I need to login remotely (without setting up more port-forwarding on a new router for that segment).
What I thought of doing was to define two scopes for IPs (10.0.10.100 to 10.0.10.199 and 10.0.1.11.100 to 10.0.11.199) allowing 400 devices on the network. My servers are on 10.0.1.x, and various devices have static IPs which is why I am not giving out IPs from x.x.x.1 to x.x.x.254. If I keep my current scope as it is (due to servers/printers/etc), not give out any dynamic IPs on 10.0.1.x, but rather create the two scopes mentioned above on the same server to give out dynamic IPs within a certain range, should everything be able to communicate as before? Will the dynamic IPs handed out be random from each of the two scopes that have the dynamic range assigned? I was also wondering if I had some HP1800 procurves, if it would be simple enough to have all devices past the point of that switch be assigned IPs from the second scope as opposed to the first scope?
