IDNs   Internationalized  Domain  Names

Intitially the domain name were in ASCII. But later on the ICANN ( Internet Corporation for Assigned Names and Numbers) decided to launch the IDNs.

Then meaning of IDNs is to launch the domain name in other languages like Hindi,Korean and Chinese like,IDNs- internationalized domain namesNow a days there is very hard to get the generic .com domain name and if it is available then it is very expensive so IDNs made this thing easy. Some of new gTLDs also have IDNs.
