Punycode is a way to represent domain names that use characters outside of the standard ASCII set.
So what's the big deal?
because they use characters that look similar, they can be used to mislead unsuspecting users to malicious content.
Eg: bücher.com and bucher.com. They look similar but are different domains.
Can Umbrella block these domains?
Yes! Just enter them into your domain list and it will be blocked. If you are trying to bulk upload a list containing punycode domains, please first convert them using converter such as https://www.punycode.io/.
