They can try to establish the connection, it might be something as simple as checking for updates, and not having an active connection isn't going to stop them from trying.
Now you could just use the command prompt, and run the command netstat -ano then match the pid to the program in the task manager, otherwise software like
TcpView will show you the program with the netstat information.
I found limited information on the owner of the ip address block, but as mentioned it might be hp if you have an hp computer, so they have some utility checking for updates for something. It might even be part of their bloated printer drivers.
Your best bet is to find the program, or sometimes it's setup as service, then disable it, otherwise disable checking for updates. Be careful using this software, it will help you disable, even delete entries for things running on startup, including services instead of having to dig through the registry manually.
Autoruns It's better to uninstall software properly instead of just ripping it out, even just disabling entries is better than ripping them out without being properly uninstalled.
