On Wednesday, February 8th 2017 Cisco Umbrella released the Umbrella roaming client for OS X version 2.0.35 for all customers on the stage track.
CHANGE SUMMARY (2.0.31 to 2.0.35)
- Improved the probe test for a customer's networks. The probe test now verifies, first, that the domain name provided by the customer for the customer probe resolves to a private IP address, and, second, that the response for a lookup of debug.opendns.com returns no answers. The first test is to identify whether or not the ISP redirects unknown domain names (NXDOMAIN) to an advertising page (which would have public IP addresses). The second test verifies that the network to which the customer is connected does not have a captive portal (which would return a private IP address sending the browser to a login page). If both tests succeed, the customer probe test passes.
