Registration Considerations
VeriSign® Internationalized Domain Name (IDN)
program is following IETF
standards related to IDN. There are important points to consider
when registering an IDN as more revisions or updates could be made in
the future.
- The IDN Program allows a registrant to register IDNs through a Registrar.
- Currently, registrants
may register domain names in any script supported by Unicode.
- The registrant's
IDN is stored in the Registry's database in an ASCII-compatible representation
as defined by RFC 3492 (Encoding Scheme: punycode).
- The uniqueness of
a domain name registration is determined by its Unicode representation.
- VeriSign
processes IDN transactions in the same manner as with all registrations
in the .com and .net Shared Registration System (i.e., on first-come/first-served
basis)
The Internet Engineering Task Force (IETF) has published standards
related to IDNs. VeriSign has migrated to the standards.
The IDN standards differ slightly from the deployed Internet draft documents
as far as allowable types of registrations.
- These revisions
may cause the registrant's domain name registration to become invalid
and be deleted.
EXAMPLE: Future changes to the standards may result in some IDNs becoming
invalid because they contain illegal characters or characters which
may no longer be permitted due to name prep standards.
- These revisions
will cause modification to the VeriSign Registry's internal representation
of the domain name to comply with revisions to the Internet draft documents.
- For each occurrence,
VeriSign will offer the affected registrar a free replacement registration,
subject to availability. The replacement registration will provide a
new domain name registration with an equivalent term as the invalid
IDN registration.
- Valid
characters for the testbed are defined by the Unicode
Code Point List.
