I'm wondering for what purpose one would be interested in finding out if a site is hosted in Iran or not.
It’s illegal for US companies to do business with anyone in Iran.
I'd rather not do business there.
Im guessing - its for some protest action? ... but really I have NO IDEA.
Would assume it's to check if a site is foreign propaganda. A lot of the lesser-known news sites that you see linked on social media are actually psy-ops pushing an agenda, many of them foreign-based. Follow the technique in the article and you can easily blacklist Iranian ones.
