It appears the domain name Peep.com changed hand this year.
The domain name that has been owned under privacy for many years, moved to Godaddy.com in May.
The domain has been a parked page for many years as well but as you can see from the screenshot, its now the home of the Peep App.
We don;t know what the domain sold for but a couple of similar domain names, PeepingTom.com sold for $20,000 back in December 2011 and Peep.me sold for $11,750 back in 2013 according to dnpric.es
