I am trying to understand how network topologies work in large scale networks such as college campuses.
I often see the phrases /16,/24 with regards to ip addresses.
I would like to know what /16 and /24 etc. mean. I understand it has something to do with subnet masks, but my question is different.
Let's say one of /24 ip address is 124.125.126.* with subnet mask 255.255.255.0, and it can have 256-2 hosts.
I am assuming we are talking about public ips here.
What does hosts mean here? Is it 254 router can be assigned public ips here? We don't assign public ips to end user devices, they only get private ips. so I am confused what does hosts refer to here?
