Welcome to our domain detection series, where we take a look at some of the activity of the most prominent domain investors and domain portfolio owners to see what they’ve bought, sold, or dropped recently. In this edition, we take a look at some of Frank Schilling’s sales, an outstanding acquisition by Nat Cohen and a potential two-letter .COM domain name sale. Media Options completed the purchase of Murphy.com this week after acquiring it for $50,200 on NameJet, according to NameBio.com. Nat Cohen acquired the domain name Diameter.com and looks to have sold Humbly.com to Humbly, LLC of Philadelphia. 4.CN acquired over forty four-letter .COM domains and several five-number .COM's on behalf of its clients. They look to have also been active with three-letter .COM acquisitions recently, too. Escrow.com are now handling the sale of Happy.co, according to WHOIS. The domain is now being used by HappyCo. Another .CO domain, Draft.co looks to have also entered Escrow.com's holding account very recently. The domains DIK.com and VXE.com have been sold at Sedo.com and are currently using domain privacy. NameFind sold many three-letter .NET domains, as well as several five-number .COM domains. Frank Schilling sold Math.net, Knuckles.com and DNHO.com, to name just a few recent transactions. Frank continues to add to his portfolio by purchasing many two-word .COM’s such as AirportWorld.com, FriedEggs.com and SoundAngel.com. The two-letter domain GG.com may have sold after the domain came out of privacy protection at eName.com. Thanks to DomainIQ for providing the data used in this series.
