مجال المستوى الأعلى للبلد على الإنترنت
نطاق المستوى الأعلى لرمز الدولة (ccTLD) هو نطاق المستوى الأعلى على الإنترنت يُستخدم عمومًا أو يُحجز لـدولة أو دولة ذات سيادة أو إقليم تابع مُعرَّف بواسطة رمز الدولة. جميع معرفات ccTLD المستندة إلى ASCII تتكون من حرفين، وجميع نطاقات المستوى الأعلى المكونة من حرفين هي ccTLDs.
بدأت طلبات امتدادات رموز الدول في عام 1985. وشملت امتدادات رموز الدول المسجلة في ذلك العام .il (إسرائيل)، .uk (المملكة المتحدة) و.us (الولايات المتحدة). وشملت امتدادات رموز الدول المسجلة في عام 1986 .au (أستراليا)، .de (ألمانيا)، .fi (فنلندا)، .fr (فرنسا)، .is (آيسلندا)، .jp (اليابان)، .kr (كوريا الجنوبية)، .nl (هولندا) و.se (السويد). وشملت امتدادات رموز الدول المسجلة في عام 1987 .ar (الأرجنتين)، .ca (كندا)، .ch (سويسرا)، .cl (تشيلي)، .dk (الدنمارك)، .my (ماليزيا)، .nz (نيوزيلندا) و.no (النرويج).[1] وشملت امتدادات رموز الدول المسجلة في عام 1988 .at (النمسا)، .be (بلجيكا)، .es (إسبانيا)، .ie (أيرلندا)، .it (إيطاليا)، .pt (البرتغال)، .sg (سنغافورة) و.th (تايلاند). وشملت امتدادات رموز الدول المسجلة في عام 1989 .br (البرازيل)، .in (الهند)، .mx (المكسيك) و.tw (تايوان). وفي عقد 1990، سُجلت لأول مرة نطاقات .ae (الإمارات العربية المتحدة)، .cn (جمهورية الصين الشعبية)، .cz (جمهورية التشيك)، .hk (هونغ كونغ)، .pl (بولندا)، .ru (الاتحاد الروسي)، .tr (تركيا) و.za (جنوب إفريقيا).
في عام 2018، بدأت هيئة الإنترنت للأرقام المخصصة (IANA) تنفيذ نطاق المستوى الأعلى لرمز الدولة المدوّل، التي تتكون من محارف أصلية للغة عند عرضها في تطبيق المستخدم النهائي. ويُوصف إنشاء نطاقات ccTLD وتفويضها في RFC 1591، بما يتوافق مع رموز الدول ISO 3166-1 alpha-2. وبينما يتعين على gTLD الالتزام باللوائح الدولية، تخضع ccTLDs لمتطلبات تحددها مؤسسة تنظيم أسماء النطاقات في كل دولة. ومع تسجيل أكثر من 150 مليون اسم نطاق في عام 2020، شكلت ccTLDs نحو 40% من إجمالي صناعة أسماء النطاقات.[2]
بحلول أواخر عقد 2010، أصبحت ccTLDs مستخدمة على نطاق واسع عبر الويب، بما في ذلك المواقع المنشأة باستخدام منشئي المواقع المستضافة وخدمات النطاقات مثل ويكس وIONOS وBluehost، التي تدعم تسجيل أو ربط مجموعة من امتدادات النطاقات، بما فيها نطاقات رموز الدول.[3][4][5]
يوجد أكثر من 300 نطاق ccTLD مفوضًا. وتضم نطاقات .cn و.tk و.de و.uk و.nl و.ru أكبر عدد من النطاقات.[6][7] وتستحوذ أكبر عشرة نطاقات ccTLD على أكثر من خمسة أثمان نطاقات ccTLD المسجلة.[6] وكان هناك نحو 153 مليون نطاق ccTLD مسجل في نهاية مارس 2022.[8]
التفويض والإدارة
IANA مسؤولة عن تحديد الجهة الوصية المناسبة لكل ccTLD. ثم تُفوَّض الإدارة والسيطرة إلى تلك الجهة الوصية، التي تتولى مسؤولية سياسات النطاق وتشغيله. ويمكن تحديد التفويض الحالي من قائمة IANA لنطاقات ccTLD.[9] وقد تختلف متطلبات ورسوم تسجيل نطاق فرعي من ccTLD إلى آخر. وقد يُشترط وجود محلي، مثل الجنسية أو صلة أخرى بنطاق ccTLD، كما هو الحال في نطاقات الولايات المتحدة (us)، واليابان (jp)، وكندا (ca)، وفرنسا (fr) وألمانيا (de)، أو قد يكون التسجيل مفتوحًا.
القوائم
في 20 مايو 2017، كان هناك 255 نطاقًا من نطاقات المستوى الأعلى لرمز الدولة، مكتوبة حصريًا بالأبجدية اللاتينية، وتستخدم رموزًا مكونة من حرفين. وبلغ العدد 316 في اعتبارا من June 2020[تحديث]، مع إضافة النطاقات المدوّلة.[10]

Proposed internationalized ccTLDs
Internationalised domain names have been proposed for Japan and Libya.
Relation to ISO 3166-1
The IANA is not in the business of deciding what is and what is not a country. The selection of the ISO 3166 list as a basis for country code top-level domain names was made with the knowledge that ISO has a procedure for determining which entities should be and should not be on that list.
— Jon Postel، RFC 1591[96]
Unused ISO 3166-1 codes
Almost all current ISO 3166-1 codes have been assigned and do exist in DNS.
However, some of these are effectively unused. In particular, the ccTLDs for the Norwegian dependency Bouvet Island (bv) and the designation Svalbard and Jan Mayen (sj) do exist in DNS, but no subdomains have been assigned, and it is Norid policy to not assign any at present.[97][98] Two French territories—bl (Saint Barthélemy) and mf (Saint Martin)—still[تحديث] await local assignment by France's government.
The code eh, although eligible as ccTLD for Western Sahara, has never been assigned and does not exist in DNS. Only one subdomain is still registered in gb[99] (ISO 3166-1 for the United Kingdom), and no new registrations are being accepted for it. Sites in the United Kingdom generally use uk (see below).
The former .um ccTLD for the U.S. Minor Outlying Islands was removed in April 2008. Under RFC 1591 rules, .um is eligible as a ccTLD on request by the relevant governmental agency and local Internet user community.
ASCII ccTLDs not in ISO 3166-1
Several ASCII ccTLDs are in use that are not ISO 3166-1 two-letter codes. Some of these codes were specified in older versions of the ISO list.
uk(United Kingdom): The ISO 3166-1 code for the United Kingdom is GB. However, the JANET network had already selectedukas a top-level identifier for its pre-existing Name Registration Scheme, and this was incorporated into the DNS root.gbwas assigned with the intention of a transition, but this never occurred and the use ofukis now entrenched.[100]suThis obsolete ISO 3166 code for the Soviet Union was assigned when the Soviet Union still existed; moreover, newsuregistrations are accepted.ac(Ascension Island): This code is a vestige of IANA's decision in 1996 to allow the use of codes reserved in the ISO 3166-1 alpha-2 reserve list for use by the Universal Postal Union. The decision was later reversed, with Ascension Island now the sole outlier. (Three other ccTLDs,gg(Guernsey),im(Isle of Man) andje(Jersey) also fell under this category from 1996 until they received corresponding ISO 3166 codes in March 2006.)eu(European Union): On September 25, 2000, ICANN decided to allow the use of any two-letter code in the ISO 3166-1 reserve list that is reserved for all purposes. Only EU currently meets this criterion. Following a decision by the EU's Council of Telecommunications Ministers in March 2002, progress was slow, but a registry (named EURid) was chosen by the European Commission, and criteria for allocation set: ICANN approvedeuas a ccTLD, and it opened for registration on 7 December 2005 for the holders of prior rights. Since 7 April 2006, registration is open to all in the European Economic Area.
Historical ccTLDs
ccTLDs may be removed if that country ceases to exist. There are three ccTLDs that have been deleted after the corresponding 2-letter code was withdrawn from ISO 3166-1: cs (for Czechoslovakia), zr (for Zaire) and tp (for East Timor). There may be a significant delay between withdrawal from ISO 3166-1 and deletion from the DNS; for example, ZR ceased to be an ISO 3166-1 code in 1997, but the zr ccTLD was not deleted until 2001. Other ccTLDs corresponding to obsolete ISO 3166-1 codes have not yet been deleted. In some cases they may never be deleted due to the amount of disruption this would cause for a heavily used ccTLD. In particular, the Soviet Union's ccTLD su remains in use more than twenty years after SU was removed from ISO 3166-1.
The historical country codes .dd for the German Democratic Republic and yd for South Yemen were eligible for a ccTLD, but not allocated; see also .de and ye.
The temporary reassignment of country code cs (Serbia and Montenegro) until its split into rs and me (Serbia and Montenegro, respectively) led to some controversies[101][102] about the stability of ISO 3166-1 country codes, resulting in a second edition of ISO 3166-1 in 2007 with a guarantee that retired codes will not be reassigned for at least 50 years, and the replacement of RFC 3066 by RFC 4646 for country codes used in language tags in 2006.
The previous ISO 3166-1 code for Yugoslavia, YU, was removed by ISO on 23 July 2003, but the yu ccTLD remained in operation. Finally, after a two-year transition to Serbian rs and Montenegrin me, the .yu domain was phased out in March 2010.
Australia was originally assigned the oz country code, which was later changed to au with the .oz domains moved to .oz.au.
Internationalized ccTLDs
An internationalized country code top-level domain (IDN ccTLD) is a top-level domain with a specially encoded domain name that is displayed in an end user application, such as a web browser, in its native language script or a non-alphabetic writing system, such as Latin script (.us, .uk and .br), Indic script (.भारत) and Korean script (.한국), etc. IDN ccTLDs are an application of the internationalized domain name (IDN) system to top-level Internet domains assigned to countries, including the United Kingdom, or independent geographic regions.
ICANN started to accept applications for IDN ccTLDs in November 2009,[103] and installed the first set into the Domain Names System in May 2010. The first set was a group of Arabic names for the countries of Egypt, Saudi Arabia, and the United Arab Emirates. By May 2010, 21 countries had submitted applications to ICANN, representing 11 languages.[104]
ICANN requires all potential international TLDs to use at least one letter that does not resemble a Latin letter, or have at least three letters, in an effort to avoid IDN homograph attacks. Nor shall the international domain name look like another domain name, even if they have different alphabets. Between Cyrillic and Greek alphabets, for example, this could happen.
Generic ccTLDs
Generic Country Code Top-Level Domain or gccTLD refers to those TLDs which are technically "non-restricted ccTLDs" but used like traditional generic TLDs (gTLDs) rather than "country"-targeted ones.[105][106][107] Most of the gccTLDs are primarily used as domain hacks:
Unconventional usage
Lenient registration restrictions on certain ccTLDs have resulted in various domain hacks. Domain names such as I.am, tip.it, start.at and go.to form well-known English phrases, whereas others combine the second-level domain and ccTLD to form one word or one title, creating domains such as blo.gs of South Georgia and the South Sandwich Islands (gs), youtu.be of Belgium (be), del.icio.us of the United States (us), and cr.yp.to of Tonga (to). The .co domain of Colombia has been cited since 2010 as a potential competitor to generic TLDs for commercial use, because it may be an abbreviation for company.[108]
Several ccTLDs allow the creation of emoji domains.
Some ccTLDs may also be used for typosquatting. The domain cm for Cameroon has generated interest due to the possibility that people might miss typing the letter o for sites in the com.[109]
الاستخدام التجاري
Some of the world's smallest countries and non-sovereign or colonial entities with their own country codes have opened their TLDs for worldwide commercial use. Some of them, such as .tk, are free.
