Infringing on a trademark can be a big issue. Whenever you have a nice .IST domain name idea and you’re just about to register it, simply google the name and look through all of the first and second-page results.
What you’re looking for are businesses that already use this name and operate in a similar market.
If you find anything, you likely need to pick another .IST domain name.
