NAT Types

 Network Address Translation

There are three different types of NAT which are Static NAT, Dynamic NAT, and also Port-Address Translation which is also known as NAT Overload. Static NAT is a one-to-one mapping of an internal private address into a public address. These types of NAT are some of the main types and there are some others like gaming types of NAT that I will not go over in this blog post.

Dynamic NAT is a one-to-many mapping with one private address and many public addresses. The Port Address Translation is used with a single public address and multiple private addresses. PAT, also known as NAT overload, is used mostly by home routers and is the most common type. PAT is done using port numbers for each session that is connected by each IP address.

Static and Dynamic NAT

The static NAT type is used mostly by people hosting a server in a private network behind a firewall or router. The dynamic NAT type of Network Address Translation is used by companies to map their IP addresses. This results in a one private IP to multiple public IP addresses. This is most commonly done by companies with larger networks.

There are some things to work on regarding computer networking certifications. The certifications that this will help with the most are the CCST Networking and the Network+ certification. Certification study is one of the best things that you can do for your career and will help you get better jobs over time along with some education.

In order to understand a book or course you would want to section off the information in a study plan and be consistent in order to finish the study plan before taking one of these exams. With a study plan there is built in consistency, and you will want to keep pace with your study sessions. This is in order to pass the exam or class that you are in. If you stick to your plan, you can make it better or do better things with it next time.

Conclusion

These types of NAT are the main types and will help you out on exam day if you can put in a solid study plan along with some reading. I do have the CCST Networking and the CCNA along with other certifications and this information has helped me with those exams. When working on a study plan it should include some reading, practice, and thorough online course study.
