The key to understanding the way that subnetting works in AWS is to keep in mind that when you create a CIDR block, you are not actually creating any subnets. Subnets have to be created separately and ...

With the combination of CIDR and the global depletion of IPv4 addresses we have all learned to do IPv4 subnetting in our sleep. We divide and chop up our IPv4 blocks into smaller and smaller subnets.

You also write down that the default subnet mask is 255.255.0.0. And just to jog your memory, you write down that the network you are using is then 172.16.0.0/16, because /16 is the CIDR notation for ...

Configure the IP addresses, subnet masks and default gateways in the Web server's network interfaces configuration file based on what you purchased.

I'm doing a lab in Boson, where it gives you the topology with some ip addresses and then expects you to do show running-config to get the subnet mask, and get the Network Address, First Host ...
