Overview
Sometimes when viewing your Top Domains reports will see domains with a wildcard attached to them. Some of the most common examples of this include domains such as the following:
- *.dyndns.org
- *.amazonaws.com
- *.l.google.com
What are they?
Cisco umbrella makes use of a Domain Trimming feature in the Top Domains report, as well as in Scheduled Reports. This feature takes a group of subdomains and groups them together as a singular domain with a wild card attached to it. If we didn't do this, the Top domains reports would be littered with these sub domains and wouldn't have as much valuable information.
To provide an example of this, the following domains below would count towards the count of *.l.google.com
- play.l.google.com
- www-google-analytics.l.google.com
- plus.l.google.com
- gas.l.google.com
- sandbox.l.google.com
- mobile.l.google.com
Do these domains show in full elsewhere?
The only locations that these domains show as having wildcards is in the scheduled reports, and in the Top Domains reports. Everywhere else they will show with their full domain names.
