It con- nects approximately three hundred sites, mainly universities and research organizations. ARNET provides electronic mail, USENET News, file server, and electronic mailing list ser- vices. Like other cooperative networks, ARNET has no central plan- ning or central authority. The current international link and the top-level AR domain are managed by the UNDP (United Nations Development Programme), Project ARG-86-026, at the Ministry of Foreign Affairs (MREC), together with the Secre- tariat of Science and Technology (SECYT). For the time being, the top-level subdomains are administered by the UNDP/MREC project. ARNET is a store-and-forward message network based on the Unix communications facilities. The international elec- tronic mail gateway and USENET news backbone, atina.ar, is a '386 machine running Unix System V connected to the MREC Local Area Network. The network is connected to the Inter- net through a satellite link to SURANet at the University of _________________________ The information in this section is provided in accor- dance with the copyright notice appearing at the front of this guide.

Most ARNET connections are over the public telephone network or the public packet-switching network, ARPAC, using the UUCP protocol in different environments. USENET news and most electronic mail traffic is brought to ARNET from uunet.uu.net via Internet. Several major nodes, such as secyt.gov.ar (Secretaria de Ciencia y Tecnologia), dcfcen.edu.ar (Departamento de Compu- tacion, Facultad de Ciencias Exactas y Naturales, Universi- dad de Buenos Aires), and opsarg.org.ar (Organizacion Panam- ericana de la Salud), call atina.ar over telephone lines, PSN ARPAC, or leased lines to distribute mail and news traffic to other nodes. Many nodes use various implementa- tions of UUCP for MS-DOS with limited functionality. Future plans There is a cooperation agreement between the UNDP/MREC pro- ject and the SECYT to distribute Internet services. The first stage will be the installation of a couple of Unix boxes at major regional sites, interconnected through the PSN ARPAC and national satellite links using UUCP. The second stage will be the migration from UUCP to TCP/IP. There are under study different ways to distribute Internet services throughout the country, and to upgrade the interna- tional link to the Internet. _N_e_t_w_o_r_k _A_c_c_e_s_s ARNET's IP number is 140.191. Several bits of the address are reserved for subnetting. The subnet mask is 255.255.254.0. The current MX-host for the AR domain is uunet.uu.net. Domain Name Service for AR domain is served by NS.UU.NET and UUCP-GW-1.PA.DEC.COM. Most systems on ARNET use the Inter- net addressing scheme and the UUCP bang notation. 9 Top-level-domain: AR (Argentina) Internet: user@node.subdomain.ar UUCP: uunet!atina!node.subdomain.ar!user or uunet!atina!node!user There are several top-level subdomains. Provincial sub- domains are used when sites don't apply for organizational subdomains. 9 July 26, 1991 NNSC Section 5.43, Page 2 edu.ar Academic and research institutions org.ar Non profit organizations gov.ar Government institutions and agencies com.ar Commercial organizations mil.ar Military institutions mrec.ar Ministry of Foreign Affairs Network ba.ar Buenos Aires cb.ar Cordoba cc.ar Chaco ch.ar Chubut cn.ar Corrientes ct.ar Catamarca er.ar Entre Rios fm.ar Formosa jy.ar Jujuy lp.ar La Pampa lr.ar La Rioja mn.ar Misiones mz.ar Mendoza nq.ar Neuquen rn.ar Rio Negro sa.ar Salta sc.ar Santa Cruz se.ar Santiago del Estero sf.ar Santa Fe sj.ar San Juan sl.ar San Luis tf.ar Tierra del Fuego tm.ar Tucuman _M_i_s_c_e_l_l_a_n_e_o_u_s _I_n_f_o_r_m_a_t_i_o_n ARNET UUCP maps are available from USENET News or uunet.uu.net.
