Register your own domain at Godaddy and have that domain forwarded to your auction or event page.
The link below will show steps on how to forward a domain using Godaddy.
From the link above, scroll down to the section called: “To forward or mask your domain or subdomain”.
1) Put in the full Auction or Event URL.
2) You can select Forward Type: “Temporary (302)”
3) For Settings, select “Forward Only”.
NOTE: The Forward with Masking will not work with our site. You will need to use Forward Only.
Make sure you test your new domain to see if you land on your auction page once it’s complete.
