What CIDR block will let Site Server connect to all IPs?





Entering the above CIDR block in the "Managed Subnet Address(es)" field in Site Server Config will allow it to connect to all possible IP addresses.  Other CIDR blocks can be used to narrow the field of agents that a Site Server has access to.  For more information on Classless Inter-Domain Routing (CIDR) and how to configure specific ranges, please see the article below.
