It was just announced that Doma.com was recently acquired by Francois Carrillo, and it is being used as a URL shortener of sorts for Domaining.com. Instead of typing in Domaining.com, you can simply visit Doma.com and end up in the same spot.
In Russian, Doma means “at home,” and it wasn’t cheap. In January of this year, Sedo reported the $7,500 sale of Doma.com. According to Carrillo, the domain name was acquired by his company via domain swap (using Carrillo’s eCop website), although I don’t know what was traded to get this particular domain name.
Francois owns a number of domain industry serving domain names and websites including the aforementioned Domaining.com, Cax.com, NumericDomains.com, DomainHacks.com, eCop.com, and others.
Congratulations on the acquisition.
