Different Class Networks

[StressedTechie]

I have just taken over the running of IT in an Office. I am solely responsible for everything now. My question is before I joined they split from a major network and are now a seperate entity.

It looks as though they kept the IP addresses that were assigned to them when they were larger.

So we seem to have 40 or so clients using Class A ranges. Does it really matter what type of range you are using. I am guessing not. Its the initial setup that is the cost decider.

If you are talking internal (private) IP addresses then it doesn't matter as long as you keep to the same subnet.

If you only have 40 or so, you may want to migrate everyone to 192.168.0.x 255.255.255.0, but it makes little or no difference in the real world...
