By attempting to connect you will implicitly query DNS (which itself
is a connection to server).
No it's not - it's putting out a packet targeted at an IP address
and hoping a server will answer - hence why multi-cast works for
DNS because you're not directly
I think the only way to detect if it can connect to the Internet is to
see if you can grab a file from somewhere on the Internet. I'd hazard a
guess that when operating systems are able to tell you they can connect
to the Internet they are actually saying they can ping a predetermined

Why can't you put the update on the same LAN server that the app resides?
If that is not possible, what about using CURL, and update if it can connect
successfully, but don't if it cannot?
