One challenge I am facing is that there are cases where the product I am working on is run within a network that does not have extranet access, but need to access a server inside the network. I do not know what the domain or address is for this server, since it is different for each installation.

So before I try to communicate with the server, I would like to know that I can actually get off the machine to some kind of network. This will help avoid having to wait for curl to timeout. It looks like NSHost and SCNetwork... depend on having a specific address or domain. How can I just determine if there is a physical connection to a network?

I am currently use NSHost to determine if I can see a particular domain, before I initiate a lengthly sso to that domain. However, I am finding that depending on the settings of some network DNS servers, this method does not always work. Any suggestions of a better way to confirm a live internet connection?
