@siringo said in Changing subnet mask?:
If I get the Cisco gear changed, prior to me changing the servers, PCs, printers etc to /24 will everything remain working??
For example, If I get the Cisco gear changed to /24 on weekend 1, will everything still communicate & work fine until I can change the other gear on weekend 2??
I know the subnets are different, but with all devices having 10.0.0.x addresses I'm thinking they still may be seen by the /24 devices????
Does that make sense?
From what i remember
no they won't talk to each other once they are on a /24
e.g. 10.0.1.X/24 wont talk to 10.0.2.X/24
Have you checked the devices are using different IPs? 10.X.X.X? if your lucky they might all be on 10.0.X.X/24
