IDN Spoofing Concerns
Domain name spoofing works by exploiting the visual resemblance, or near- resemblance, of certain characters and symbols. ICANN is concerned about the potential exacerbation of domain name spoofing as IDNs become more widespread, and is equally concerned about the implementation of countermeasures that may unnecessarily restrict the use and availability of IDNs. ICANN's public comment forum on this topic is available here.
