.NA is the Internet country code top-level domain (ccTLD) for Namibia corresponding to the two letter code from the ISO-3166 standard.〔http://www.iso.org/iso/country_codes.htm〕 The registry accredits both Namibian and foreign registrars. Registrars access the Registry and register domains using either a web-based GUI or the industry standard EPP protocol. .NA was established on 8 May 1991. The ccTLD manager is NA-NiC (Namibian Network Information Centre).〔http://www.iana.org/domains/root/db/na.html〕 The Namibian Parliament passed a Communications Act in 2009 containing various provisions regarding the ccTLD;〔http://www.cran.na/dloads/Regulations/Government%20Gazettes/GG%205595%20-%2020%20OCTOBER%202014.pdf〕 however as of the beginning of 2015 these had not yet entered into force. Registrations are available at both the second level or at the third level beneath various names that include some apparently redundant choices (e.g., both .co.na and .com.na for commercial entities). == Domain registration costs == Domain registration prices to the end-user are now set by registrars in competition with each other. Wholesale prices (the cost to the registrars) depend on the level at which a registration is made (i.e. whether at second-level or a third-level registration) and also whether the registrant is domestic or foreign. The second-level is considered 'premium', so the cheapest domains would be a registration by a local organisation at third-level (such as the NamNumbers telephone directoryt at TELECOM.COM.NA〔http://telecom.com.na/〕 whilst the highest prices are paid by non-Namibian entities registering at the second-level (such as BRITISHCOUNCIL.NA)〔http://www.britishcouncil.na〕 On occasion, it has been suggested that .NA may have some unofficial use as meaning North America but there is little or no evidence for this. NA-NiC is a member of CoCCA and uses their Dispute Resolution. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「.na」の詳細全文を読む スポンサード リンク
