The Guidelines are a list of general standards for IDN registration policies and practices that are designed to minimize the risk of cybersquatting and consumer confusion, and respect the interests of local languages and character sets. Registries seeking to deploy IDNs under their agreements with ICANN have been authorized to do so on the basis of the Guidelines.
