When I search the real-time airline information by Google, I found a site named http://airinfo.aero/
It looks so strange. I have never seen a top level domain with four letters. There are very common three letter domain or two letter domain, like .com, .net, .uk, .cn, .cc.
This time it is four letters – aero.
After doing some research, I got the answer.
.aero – the world’s first industry-based top level Internet domain
Reserved exclusively for aviation, .aero is inspiring a revolution in the way people access and use air transport information.
Registration service is provided by http://www.information.aero/
Not anyone can register an AERO domain. The eligible rule is here
It’s so cool to have a dot AERO domain.
