Issue/Introduction

A managed computer from a subnet, that is not assigned to any site, was downloading packages from the Notification Server (NS) directly.

A subnet is a logical grouping of connected network devices. A supernet is a combination of subnets into one network with a single classless interdomain routing (CIDR) prefix. 

A subnet that belongs to a supernet is called an 'Encompassed' subnet in the SMP Console. Computers from an encompassed subnet will download packages from Package Servers that are linked to a site the supernet is assigned to. There is no report that could clearly demonstrate the subnet - supernet bindings in the Console. 

Also, no errors would be reported in the logs

Environment

ITMS 8.x

Cause

Working as designed. 

Resolution

The default report "Subnet to Site assignments" has been available since ITMS 8.1 HF1 and takes care of this.  The following explains how the report should be understood:

-If 'Site' is empty -> the subnet is unassigned.
-If 'Supernet' is emply but 'Site' is not ->  the subnet is directly assigned to the site. 
-If 'Site' AND 'Supernet' are NOT empty -> the subnet is assigned to the site via the supernet.
