  1. Status and planning reports of JPNIC 宇井隆晴(UI, Takaharu) <ui@nic.ad.jp> JPNIC Chinese Domain Name Workshop

  2. .JP domain name space • AD.JP: Network Administrative Organizations • CO.JP: Commercial Companies • AC.JP: Academic Organizations • GO.JP: Governmental Agencies • OR.JP: Other types of Organizations • NE.JP: Network Service Domains (from Nov. 6, 1996) • GR.JP: Group Domains (from Dec. 1, 1997) • ED.JP: Schools (from Feb. 1, 1999) • GEO: Geographical Domains • TOKYO.JP • YOKOHAMA.JP • ... Chinese Domain Name Workshop

  3. JPNIC Registered Domains ftp://ftp.nic.ad.jp/jpnic/statistics/Allocated_Domains Chinese Domain Name Workshop

  4. Registration Policy(ASCII DN) • First-come, first-served • One domain name per organization • Non-transferable • Local presence in Japan • Discussion underway with a view to changing these policies Chinese Domain Name Workshop

  5. Future Plan for ASCII DN • Effectuate dispute resolution procedure. • For problems of cyber squatting, conflict with trademarks, and so on. • Relax limitations for number of domain name registration. • … the above plans hopefully be realized within this year. Chinese Domain Name Workshop

  6. JPNIC Status of mDN Chinese Domain Name Workshop

  7. Current status of JPNIC • JPNIC published statement about multilingual domain name on 25th Feb, and will publish revised version very soon. • Please check our web page described in next page. • JPNIC promotes standardization actively cooperate with IETF, MINC and related organizations. Chinese Domain Name Workshop

  8. Current status of JPNIC • JPNIC formed a task forceto deal with multilingual domain name issues. • IDN Task Force is in charge of research and development of IDN issues. • JPNIC started webpage about multilingual domain name on middle of March. The URL is: http://www.nic.ad.jp/en/research/idn/index.html • JPNIC began joint meeting with another NICs for information exchange and discuss about multilingual domain name related issues. Chinese Domain Name Workshop

  9. JPNIC implementations • JPNIC has 2 own experimental implementations of multilingual DNS. • Those 2 experimental implementations were study of university students who were JPNIC IDN-TF members. • JPNIC is planning to modify our implementations referring to the requirements of us presented at 47th IETF. Chinese Domain Name Workshop

  10. JPNIC implementations –IDNX/idnx-jp • Simple DNS proxy to translate Japanese local character encodings into UTF-5. • Add invisible ZLD when .日本 is TLD in query. • Refer to IETF draft. • Design goal is to separate internationalization part and localization part easily. • No additional canonicalization or normalization in internationalization part. Chinese Domain Name Workshop

  11. JPNIC implementations –GDNS • 8bit through DNS Server based on BIND-8. • No character code conversion. • Uses character code set tag in reverse lookup table. Ex. 4.3.2.1.EUC-JP.in-addr.arpa. Chinese Domain Name Workshop

  12. Related activities in Japan • 2 companies (netpia.com and jp.io) provides Japanese domain name registration service as keyword. • i-dns.net published press-release that they will start Japanese domain name registration service as DNS within this month in alliance with 3 companies (ASCII, Crayfish and InterQ). Chinese Domain Name Workshop

  13. Issues under discussion(not decided yet) Chinese Domain Name Workshop

  14. Dispute Resolution • Multilingual domain names registration may have more disputes than ASCII domain names. • Because usually Trademarks are written in local language. • We think it needs dispute resolution process(DRP) or/and examination before registration. Chinese Domain Name Workshop

  15. Limitation of Character Set/Language • What character set should Registry allow for domain name under multilingual TLDs? • Belong to TLD’s character set • Ex) Japanese TLD(.日本) has only Japanese Domain names. • No Limitation • Ex) Japanese TLD can have Chinese, Korean, Tamil and Arabic domain names. • We think mDN character set belong to TLD. Chinese Domain Name Workshop

  16. Limitation of Characters • What characters should Registry allow for domain name? • All characters of the character set? • Symbol marks? • Similar glyph characters • … this problem has relation to canonicalization and normalization. Chinese Domain Name Workshop

  17. Canonicalization-1 • Some character sets(including ISO10646) have characters with almost the same glyph but different character codes. • For example: ‘高’ (9ad8) ‘髙’ (9ad9) ‘A‘ (0041, ASCII uppercase A) ‘Ａ’ (0391, Greek uppercase α) ‘Ａ’ (0410, Russian uppercase A) ‘Ａ’ (ff21, Japanese double width A) Chinese Domain Name Workshop

  18. Canonicalization-2 • Same glyph characters bring users’ confusion. So, we think canonicalization should be done somewhere. • In domain name registration. • In making of mDN query in resolver and/or proxy. Chinese Domain Name Workshop

  19. Normalization-1 • Same words in one language can be written in varieties of scripts. • E.g. Japanese language has 4 scripts. • Latin alphabet : tagengo • Kanji : 多言語 • Hiragana : たげんご • Katakana : タゲンゴ Chinese Domain Name Workshop

  20. Normalization-2 • Another, same problems are caused by some situations as follows: • Same meaning words • E.g. ‘国際’, ‘国家間’ • Abbreviation • E.g. ‘高等学校’, ‘高校’ • Transliteration • E.g. ‘Japan’, ‘日本’ Chinese Domain Name Workshop

  21. Normalization-3 • In multilingual domain name registration, those names should be dealt same name or not? • We think it needs normalization. But it is difficult to decide on what case normalization should be applied. Chinese Domain Name Workshop

  22. Name Space Coordination • Multilingual domain name registration services are already provided by some registries using different ZLDs and same multilingual TLDs. • Using different technology and same multilingual TLDs may cause the same problem. Chinese Domain Name Workshop

  23. When will JPNIC start mDN? Chinese Domain Name Workshop

  24. Service Schedule • JPNIC will start Japanese domain name experimental registration service after decide all of registration policy and effectuate dispute resolution procedure. • JPNIC will apply ASCII DRP to mDN DRP. • Experimental phase will continue until standardization to be finished.
