.it is the Internet country code top-level domain (ccTLD) for Italy.
Because it is also the English word it, and many words end with -it, it is commonly used in the construction of domain hacks, such as play.it, write.it or swimsu.it.
There are a number of reserved second-level domain names, for example, domain names like Italy.it, or other names that are referring to geographical regions of Italy.
