Policy development o o o o

6 October 2003 - adding the German diacritics

20 October 2003 - adding selected characters from Unicode scripts: Latin-1 Supplement and

Latin Extended-A;

3 November 2003 - release selected characters from Unicode scripts: Arabic, Greek, Hebrew;

26 February 2004 - release of characters derived from Unicode Cyrillic script.

IDN registration policy http://www.dns.pl/IDN/idn-registration-policy.txt

o registered only ASCII form of an IDN o o allowed characters are divided into sets:

Cyrillic, Greek, Hebrew, Latin (includes characters from Latin-1 Supplement and Latin

Extended-A) mixing characters from different sets is not allowed

Geneva, 9-11 May 2006

13

IDN registration policy o o

If an IDN contains only ASCII alike characters from the

Cyrillic set: digits, hyphen “-” and a (U+0430), e

(U+0435), o (U+043E), p (U+0440), c (U+0441), y

(U+0443), x (U+0445), s (U+0455), i (U+0456), j

(U+0458) then:

• Cyrillic characters are mapped to similar ASCII characters

• check is performed whether a translated domain name into ASCII characters is registered yet or not

• if the translated domain name into ASCII characters

(e.g. 123-coca.pl) is registered, then registration of the

IDN is forbidden.

Plans

Preventive system against domain spoofing.

The special “anti-spoofing” mechanism will be implemented in the registry system. The mechanism, is to filter out all singlescript spoofable domains (not only IDNs) during a registration process, create variant domains in accordance with a mapping table and check against existing domains (both IDNs and ASCII one). A registration process will be finished successfully when neither being registered domain nor its possible variants exist in the registry system.
