как называется .ru

[shellesie.livejournal.com]

путаюсь в понятиях "домен" и пр.
Как правильно называется то, что после точки? ru, com, ua...
Что там еще про "домены первого/второго уровня" - это что?

Короче, смотрим тут: http://www.nic.lv/DNS/rfc/rfc920.html

 The initial top level domain names are:

    * Temporary

               ARPA  =  The current ARPA-Internet hosts.

    * Categories

               GOV  =  Government, any government related domains meeting the
                       second level requirements.

               EDU  =  Education, any education related domains meeting the
                       second level requirements.

               COM  =  Commercial, any commercial related domains meeting the
                       second level requirements.

               MIL  =  Military, any military related domains meeting the
                       second level requirements.

               ORG  =  Organization, any other domains meeting the second
                       level requirements.

    * Countries

               The English two letter code (alpha-2) identifying a country
               according the the ISO Standard for "Codes for the
               Representation of Names of Countries" [5].

    * Multiorganizations

               A multiorganization may be a top level domain if it is large,
               and is composed of other organizations; particularly if the
               multiorganization can not be easily classified into one of the
               categories and is international in scope.

есть два термина. "Intended use" и "Actual use". Предполагалось military вообще, а на самом деле - исключительно США.
