The Soviet Union lasted long enough to be given it’s own internet domain name, .su, which it received only 15 months before dissolving.
The guy who snagged windows2000.com happened to be named Bob and Microsoft just happened to own Bob.com. They came to an agreement to trade one for the other.
The longest-running legal battle for a domain name is believed to be the fight for PETA.org. People for the Ethical Treatment of Animals sued People Eating Tasty Animals to obtain the name – the case spanned from 1995 to 2001.
