I often get the question from customers "How do I make a browser trust my internal Intranet web server". Is it possible to use trusted certificates for Intranet servers? The short answer is yes. It is possible, and I'll show you two ways this can be solved. But what exactly is an Intranet server?
What Is an Intranet Server?
An Intranet (internal) server is one that runs on a private (home/business) network with a non-public IP address -- that is, any IPv4 address in the RFC 1918 range (e.g. 10.0.0.0, 172.16.0.0, 192.168.0.0) and any IPv6 address in the RFC 4193 range.
