Join Brian Eiler for an in-depth discussion in this video CIDR blocks, part of Amazon Web Services: Implementing and Troubleshooting IaaS Products.
- [Instructor] One of the fundamental building blocks…of networking, at least today, is the IP address.…But, somehow we have to figure out…where do the IP addresses come from?…In other words, which addresses are we allowed to use…for one thing versus another thing?…And for that, AWS elected to use…CIDR blocks for the VPCs.…CIDR is an acronym, C-I-D-R,…it stands for classless inter-domain routing.…It was a convenient way to actually designate…what the subnet mask is…for a given set of IP addresses, choose tier.…
For example, 10.0.0.0/16.…That indicates that we have a subnet mask of…255.255.0.0,…and without going through a deep dive in networking,…what this means is we can determine…the number of IP addresses that are available…inside of that subnet.…For example, if we look at the chart to the right,…we can see that a /16 subnet…is going to give us 65,000 IP addresses.…
That's a lot.…Now, not all times will you really want to have…one large network where you'll have 65,000 devices…in one spot, or in this case, one availability zone.…
