I use Uniregistry market. All of my domains are listed in Godaddy auctions except Auction.direct. Below message pops up when I try to list it manually. Also please note that my other .direct domains are listed in Godaddy auctions. So it is not that Godaddy has issue with the extension. While GoDaddy Auctions supports the vast majority of Top-Level Domains, we can`t list this particular domain right now. We`re working on building out the infrastructure to handle domains like this and will email you when we`re ready to go.
