Internet Top Level Domain - AS
When I had my sailboat I use a domain name that I purchased to match my boat name and had emails for my wife and myself setup using that domain.
We are in the process of purchasing an Airstream (AS) (2017 Sport 16') and have thought about naming it. As a result, I started looking for domain names and most of the ones I checked ending in .ca, .com, .net etc were taken. After a bit of research I learned that the the top level domain extension for American Samoa is AS. I quickly registered the domain of my choosing. It was more costly than getting something at GoDaddy, but still, IMHO a unique investment.
