One of those techniques is using facsimiles of legitimate brand names in Web addresses to redirect victims to outlaw Internet sites where the scammers can work their mischief on their targets, a practice called […]

Internationalized Resource Identifiers (IRI’s) are a new take on the old URI (Uniform Resource Identifier), which through RFC 3986 restricted domain names to a subset of ASCII characters – mainly lower and upper case letters, numbers, and some punctuation.

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.
