Expanding our IP range - possibly a stupid question
Ok...we have 3 sites, all currently with a class C /24 address range:
Site A - 192.168.1.0/24
Site B - 192.168.5.0/24
Site C - 192.168.10.0/24
Each giving 254 hosts per site. None have run out yet, but site A is the most likely to (site B & C very unlikely)
By supernetting, and changing the subnet mask to /23 I can expand to 510 hosts per subnet right? So 192.168.0.1 - 192.168.1.254 in site A? But if I do this for site A, would I have to do ir for the other sites and any future sites/VLANs too? Or could the others stay on /24?
Or would an easier solution be to have both 192.168.1.0/24 and 192.168.2.0/24 for site A and route between them?
