But in real-world usage the word "internet" always refers to the internet. You would never refer to "an internet"—more likely terminology would be "intranet," "LAN" or "corporate network," or, in a historical context, something along the lines of "internet precursor."

That's exactly why you capitalize it - because you refer to a specific thing. The Internet, God, the United States, etc.

"the moon", "the sun", "the planet"

Last time I checked it was "the Moon", "the Sun", and "the planet Earth".

Is that really the AP style? If so I agree it's strange not to keep "the Internet".

As of 2009, it was "moon" and "sun."
