Large Subnet

At my office, we currently have a class C subnet so it's limited to 255 devices on the network. Is there a downside to changing it to a class A or B subnet? Does it slow it down?

Also, what does it mean when they say the subnet is 192.168.1.1/24?

Check out the Online IP Subnet Calculator. You will get an idea of how subnet masks work.

The 24 means that the first 24 bits are valid for compare.

Thus for comparing only 192.168.1 are relevant, not the 0 to 255 for the last part of the address.

Changing the range is simply done by changing the netmask (or 24 in this case) to e.g. 255.255.254.0 (= 23), which gives a range of 512 id's (= 192.168.1.x and 192.168.0.x). So i suggest you change the base address to e.g. 192.168.2.1, leaving you the ranges 192.168.2.x and 192.168.3.x).


Good luck, Kees
