Large Subnet

[supanatral]

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.

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

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
