Filtering your IP and those of your employees, advisors, friends, your mom (who's your number one fan and can stop watching you video over and over) is a great way to keep your data clean and look at how the people that really matter to your business interact with your videos.
To do this, click on your name at the top right of your dashboard.
Once in your account page, scroll down to the IP Filtering section. Simply type in the IPv4 address you want to block, give it a name, and click save.
All the views from this IP will be removed from your data, even retroactively!
Note: If somebody gives you an IPv6 address (which would look like this: 2001:0db8:85a3:0000:0000:8a2e:0370:7334), you'd need to convert it to IPv4 in order to add it to your filters.
You can use this tool to do so :)
