Neustar have had their dotbrand, .neustar, for a while. At the moment it’s not very visible, but that could be changing.
In an email to registrars the registry operator announced that they’re switching the hostnames of some registry related services over to .neustar domain names.
Currently more public facing domain names such as www.neustar redirect to the existing NeuStar.biz site.
Whether this will change at some point in the future or not remains to be seen.
