When running a reverse-DNS lookup on a few IP addresses in Korea or Japan, I was getting either "apuc10", "apuc20", or "apuc21" reposes back. I'm not sure what these mean. If anyone had some detail or could point me in the right direction I'd most appreciate it.

Almost impossible (for me anyways) to answer this question without more
details. What tool did you use to do the query? What exact query did you
send? What was the response? Where in the response did you see those
strings?
