It describes problems both at the time of registration and for use of those names in the DNS. It recommends that IETF should update the RFCs relating to IDNs and a framework to be followed in doing so, as well as summarizing and identifying some work that is required outside the IETF. In particular, it proposes that some changes be investigated for the Internationalizing Domain Names in Applications (IDNA) standard and its supporting tables, based on experience gained since those standards were completed.
