Remembering the default port number for everything is not an easy task. Unfortunately, administrators need to follow this rule all the time—memorizing the most common port numbers for HTTPS, SSH, etc.
Of course, since you are working on different protocols at the same time, identifying all of their port numbers is quite difficult. In this post, we have listed the most common default port numbers for different applications to save you time. Thus, you can bookmark this post on your browser and come back whenever you need to know the default port number of a particular protocol.

Conclusion
As you can see, trying to remember all the port numbers of so many protocols is not worth it because you will forget them anyway. That’s why this list will help you identify them whenever you are at work. Open this list and search for the default port number you don’t remember.
For example, when you are trying to remember the port number for SSH, open this post from your bookmarks and press CTRL+F on your keyboard to search for SSH, and you will find its default port number. To learn more important information like this, go check out our other relevant blog posts.
