The two letter .com domain KC.com changed ownership recently, and it’s quite possibly yet another sale.
According to WHOIS changes, the domain was owned by British company Abstract Solutions in the past, and as recently as in May it was brokered by Igloo.
The current contact information is that of Chinese ownership.
Due to the high demand of short domains by Chinese investors and companies alike, many LL .com domains have been sold recently.
Domain investor, George Kirikos, keeps track of such changes.
