            ARNET, a TCP/IP network connected to the  Internet,  is  the
            major  science  and  research network of Argentina.  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
            _________________________

            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.

            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.

                  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.
