I understand that in some cases this question would regard programming but in my case it poses as some quality. I sort of understand how IP works, its octets and its bits, the Network and the Host. I understand that subnetting helps break down the larger amounts of hosts into smaller manageable hosts. What I dont get is how they match subnet with the IP.
I have a Network+ Study Guide (Thick book), but too much detail is throwing me off. Like Class A,B,C is mentioned in the book, but then I read an article on online where classes arent used anymore, which is why subnet masking came in.
Like for example, how do they match:
192.168.1.100
with
255.255.255.0
I know that probably isnt exact, but I could use more depth to understanding. Much help would be appreciated.
