AWS Certified Cloud Practitioner (CLF-C01)- IP Addresses and Subnetting - Part 2

This video tutorial is a continuation of IP addressing and subnetting, focusing on subnet masks and their role in defining networks. It covers Class A, B, and C subnet masks, explaining how they determine the number of networks and hosts. The tutorial introduces CIDR for more flexible IP allocation, providing examples and calculations to illustrate subnetting concepts. Advanced techniques and future networking concepts are also discussed, preparing viewers for on-premise and cloud networking.

What is a subnet mask and how does it function in IP addressing?

Explain the difference between Class A, Class B, and Class C networks in terms of the number of hosts they can support.

How does subnetting help in conserving IP addresses?

What is CIDR and how does it differ from traditional subnet masks?

How do you determine the subnet mask for an IP address given in CIDR notation?

What happens when you borrow bits from the host portion of an IP address?

Explain how to calculate the total number of networks that can be created with a given subnet mask.

What is the significance of the first and last IP addresses in a subnet?

Describe the process of calculating the number of usable IP addresses in a subnet.

What is the formula used to calculate the total number of IP addresses in a subnet?
