Are you looking for the best IP addressing and subnetting course online? If yes, we’ve put together a list of the best cloud computing courses on the internet. We’ve included both free and paid courses to give you a variety of options.

But first, let’s answers an important question – what is IP addressing and subnetting?

An IP address is a 32-bit number that identified a host computer (or other device such as a printer or router) on a TCP/IP network. IP subnetting is a method for manipulating the 32-bits available in the IP address and dividing a single, physical network into smaller subnetworks.

There are many benefits of subnets, which include:

  • More efficiently allocating a limited IP addresses from a limited range
  • Improves network performance as running lots of network devices on the same subnet can gum up the works
  • Makes IP networks more secure and easier to manage as creating multiple networks confines traffic, network breaches or virus outbreaks

To learn to master IP addressing and subnetting, you don’t need to spend hours at a university completing a computer science or information technology degree. There are still plenty of online classes and courses that cover everything you need to know. Suitable for those of all levels, I have spent the time researching the best IP addressing and subnetting courses  online out there.
