Hi
About to change routers & ISP & while I am about it want to give myself a larger IP range.
Currently 192.168.2.1 /24, so 1 - 255
I have very many static devices in range 192.168.2.1 to 192.168.2.100 so all set up with 255.255.255.0
DHCP 101 - 255
If I put this new router in, set up with /23 so 192.168.2.1 - 192.168.3.255 (.3.) : 255.255.254.0
Will I be able to access these devices via a browser etc. on the LAN, i.e not have to plug in direct to each device.
To either change the subnet mask immediately or ideally leave as it is & change at my leisure.
They would still be in the new routers IP range but not sure how the subnet mask effects how the router will see them & other broadcasting potential issues.
Thanks I/A
Also, before everyone says, who needs more than 254, firstly with so many devices & IoT, smart devices/plugs 254 is actually not that huge but the way I like to manage my static does mean it is spread out & perhaps not really 254 devices.
v. roughly e.g.
192.168.2.x
1 - 5 : 2 Modems & router
10 - 20 : Main PC's - only 3 in use, other dhcp
21 - 30 : phone system & NAS , only 3 in use
31- 50 : Business IP cameras, 12 in use
51 - 60 : home IP cameras, 8 in use
61 - 70 : Business WiFi access points, 4 in use
71 - 80 : Home WI Access Points, 3 in use
etc. etc/
I like to give static ranges to Sky devices, Shelly1 devices etc etc so v. easy to get to 130 or more.
If you don't leave a decent gap, all of sudden they area mess.
DHCP then on many phones, tablets, other PC's, dozens of smart sockets/plugs, watches, ip phones...
