Completion of IANA Selection of IDNA Prefix. On 11 February 2003, the IANA selected "xn--" as the IDNA Prefix. Per our message below, the IANA requested that comments be sent no later than 13 February 2003 if there was any disagreement with the results. No comments were received regarding the computation described below. The ACE prefix for IDNA is "xn--". As stated in number 6 below, the RFC Editor has been notified of the selected code. Thank you, Internet Assigned Numbers Authority ********************************************************************* Message from 11 February 2003 regarding IANA Selection of IDNA Prefix ********************************************************************* Results of IANA Selection of IDNA Prefix As described in section B of the Protocol and Schedule (see below), today 11 February 2003 (Tuesday), is the Selection Day. The IANA followed the steps described in section 4 (see below). The twelve stocks and their trading volumes (in 100s) were: (NYSE) IMS Hlth RX 22157 (NYSE) IL Tool ITW 11795 (NYSE) IntRectifr IRF 5742 (NYSE) IBM IBM 78719 (NYSE) IntPaper IP 16609 (NYSE) Interpublic IPG 34961 (NASDAQ) Inamed IMDC 1567 (NASDAQ) Informatica INFA 4357 (NASDAQ) Inktomi INKT 6085 (NASDAQ) i2 Tch ITWO 37777 (NASDAQ) IDEC Pharm IDPH 18754 (NASDAQ) Intel INTC 524545 These trading volumes have been used to generate a key string in the manner specified on page 5 of RFC 2777. The key string is 22157./11795./5742./78719./16609./34961./1567./4357./6085./37777./ 18754./524545./ The hex value of MD5 is BDEC8317C50316D67B688D1C9A34C682 The hex value of MD5 was then divided by eighteen. The remainder of the division (10) plus one (11) is the position of the selected candidate in the ordered list below. According to the ordered list, the selected code is "XN". 1. XB 7. XH 13. XQ 2. XC 8. XJ 14. XR 3. XD 9. XK 15. XT 4. XE 10. XM 16. XW 5. XF 11. XN 17. XX 6. XG 12. XP 18. XY As stated in section 6 of our message below: If anyone disagrees with the computation of the result under the above protocol as announced by the IANA on the Selection Day, please send a note to <iana@iana.org> no later than the day before the Notification Day. The RFC Editor will be notified of the selected code on the Notification Day (Friday, 14 February 2003). Thank you, The Internet Assigned Numbers Authority ************************************************************************ -----Original Message----- From: IANA [mailto:iana@iana.org] Sent: Monday, February 10, 2003 2:44 PM To: idn@ops.ietf.org Subject: FW: IANA Selection of IDNA Prefix This document sets forth the protocol by which the IANA will select a two-character code to be used as the first two characters of the ACE prefix referred to as "IESG--" in Section 5 of draft-ietf-idn-idna-14.txt. It also specifies the schedule for the selection. This document is based on the IANA's proposed Protocol and Schedule distributed on 30 January 2003 and reflects changes to address comments received by 6 February 2003. The IANA thanks Adam Costello and Simon Josefsson for their comments. A. Protocol The following steps will be used to select the two-character code: 1. The code will be selected from among a subset of the entries on the ISO 3166-1:1997, clause 8.1.3 User-assigned alpha-2 code elements: AA, QM to QZ, XA to XZ, and ZZ. The selection is limited to these codes because of the following: a) The use of numeric characters, while permitted by the Internet-Draft, would create visual ambiguities concerning the digits "0", "1", and "5". (For similar reasons, codes including the letters O, I, L, and S are eliminated in step 3.) b) The use of ISO 3166-1 the user-assigned elements removes the possibility that the code will duplicate a present or future ccTLD code. 2. An eligible subset of that list of 42 entries will be determined by eliminating the following codes due to their use, in one or more top-level domain zone files that have been reviewed, as the first two characters of second-level domain labels that have hyphens in their third and fourth character positions: AA, QM to QZ, XA, XZ, and ZZ. 3. This leaves the following subset of twenty-four candidate codes: XB, XC, XD, XE, XF, XG, XH, XI, XJ, XK, XL, XM, XN, XO, XP, XQ, XR, XS, XT, XU, XV, XW, XX, and XY. Of those codes, XI, XL, XO, and XS are eliminated due to potential confusion with X1, X1, X0, and X5, and XU and XV are eliminated due to potential confusion with each other. This leaves eighteen candidate codes. 4. A random selection will be made from among the eighteen candidates. The algorithm for the random selection will generally follow that stated in RFC 2777. First, the eighteen candidates will be arranged in an ordered list as follows: 1. XB 7. XH 13. XQ 2. XC 8. XJ 14. XR 3. XD 9. XK 15. XT 4. XE 10. XM 16. XW 5. XF 11. XN 17. XX 6. XG 12. XP 18. XY Next, the trading volume of twelve stocks on the Reference Day (see schedule below), as listed in the U.S. National Edition of the Wall Street Journal on the Selection Day (see schedule below), will be used to generate a key string in the manner specified on page 5 of RFC 2777. The twelve stocks are: (NYSE) IMS Hlth RX (NYSE) IL Tool ITW (NYSE) IntRectifr IRF (NYSE) IBM IBM (NYSE) IntPaper IP (NYSE) Interpublic IPG (NASDAQ) Inamed IMDC (NASDAQ) Informatica INFA (NASDAQ) Inktomi INKT (NASDAQ) i2 Tch ITWO (NASDAQ) IDEC Pharm IDPH (NASDAQ) Intel INTC Although the IANA's investigation indicates that all copies of the U.S. National Edition (on any day other than a Wednesday) of the Wall Street Journal should be identical, to eliminate any ambiguity the IANA will purchase a copy, which will be authoritative, on the morning of the Selection Day at a local store. In the event that the trading volume of any of the above twelve stocks is not reported in that paper, the value 0 will be used for that stock. In the event that more than six of the stocks then have a zero value, the selection will be deemed invalid and re-run in a manner decided according to the circumstances. A key string will be constructed with the numeric trading volumes of the twelve stocks (denoted in 100s and not including any thousands-separating punctuation), in the order stated above, according to page 5 of RFC 2777. An MD5 hash [RFC 1321] of the string, prefixed and suffixed with a zero byte, will be calculated. That value will be divided by eighteen, and the remainder of the division plus one will be the position of the selected candidate in the ordered list above. (Note: The Wall Street Journal currently reports share volumes in 100s. Thus, a volume of 7,660,900 shares would be reported in the Wall Street Journal as "76609" and would be represented as "76609" within the key.) The selection mechanism uses the reference implementation in RFC 2777 and the reference MD5 implementation from RFC 1321. 5. A message will be sent to the IETF Announce list to announce the selected code as well as the details of the selection. This message will be sent immediately after the selection is made on the Selection Day, according to the schedule described below. 6. If anyone disagrees with the computation of the result under the above protocol as announced by the IANA on the Selection Day, please send a note to <iana@iana.org> no later than the day before the Notification Day. The RFC Editor will be notified of the selected code on the Notification Day. B. Schedule The following schedule will be followed for the selection process: 30 January 2003 - Protocol and Schedule published, including to IETF Announce list. Comments invited to <iana@iana.org>. 6 February 2003 - Last day for comments. 10 February 2003 (Monday) - Reference Day (see above). 11 February 2003 (Tuesday) - Selection Day (see above). 14 February 2003 (Friday) - Notification Day.
