Umbrella Chromebook Client App Version 1.3.11

In a few instances, EDNS packets generated by the Umbrella Chromebook Client were getting dropped at the service provider network. Although the Umbrella resolver was able to parse these packets successfully, some service providers DNS inspection systems marked the packets as malformed.

This issue was due to an occasional error in EDNS packet size. This has been corrected in the Umbrella Chromebook Client App version 1.3.11, so DNS inspection systems can properly identify the packets as properly constructed.

In addition, customers can now configure the resolver IP and port number from their Google Admin Console. The combination of configured resolver IP and port number should be one of the following:

"208.67.222.222:53",
"208.67.222.222:443",
"208.67.222.222:5353",

"208.67.220.220:53",
"208.67.220.220:443",
"208.67.220.220:5353",

"208.67.221.76:53",
"208.67.221.76:443",
"208.67.221.76:5353",

"208.67.223.76:53",
"208.67.223.76:443",
"208.67.223.76:5353"

The following is a sample configuration file to configure the custom resolver IP and port number:

{
   "organizationInfo":
   {
      "Value":
      {
         "organizationId":<>,"regToken":"<>"
      }
   },
   "vaIPs":
      {
         "Value":
         [
             "<>"
         ]
      },
   "googleDirectoryService": 
      {
         "Value": <>
      },
      "resolverIP":
      {
         "Value": "208.67.220.220"
      },
      "resolverPortNumber":
      {
         "Value": 443
      }
}
