what does the (24) subnet translate into in a xxx.xxx.xxx.xxx format? based on a network address of 192.168.1.x

Here is the solution

by khmikkelsen In reply to subnet masks

when you are given a network address with a slash at the end such as you example of 192.168.1.x/24 - This means that you count 24 bits from the left and this is you mask. for the range of 192 (which is a class C address) /24 represents the default subnet mask which is 255.255.255.0.

To elaborate a bit further.. lets say that your example was /25. This would mean that you need to borrow one more bit from the fourth octet, thus your subnet mask for /25 would be 255.255.255.128

get it? I'll explain it some more if you need me to, just reply back or email me.
