Given the length of the video there, GIF might not be feasible. That YouTube clip provides a better option. It could also potentially draw people in to the YouTube channel for similar videos.
There are lots of cases where GIF will be better, but there are cases like the above where an auto-played YouTube video is optimal.
It’s important to know math, but if you’re in a fix, let Google do it! Just enter a math expression in Google’s search box, like so for example:
https://www.google.com/#q=75%2B10
You can always open a command prompt or terminal window and use ipconfig (ifconfig in Linux) to find your computer’s local IP and yeah, there are easy ways to get your public IP as well.
Let’s make that dead easy using Google, enter the following:
my ip
Or more directly: https://www.google.com/search?q=google+my+ip
