ripe-3 L.S., During the last year Europe has seen a growing number of IP networks with a coverage that goes beyond that of a typical LAN. Networks of regional, national and international importance have come into operation. Though these networks are operated under the separate executive authority of the various organisations that own them, a growing tendency has been observed to interconnect them on an ad hoc basis. In order to facilitate the interconnection of separate IP networks, a co-ordinating body has been formed recently by most of the organisations running IP services in Europe today. Under the name of RIPE (Reseaux IP Europeens), a framework has been set up whithin which a growing number of IP network service providers will coordinate the inter-network aspects of their services. Enclosed with this letter are documents describing RIPE in more detail, together with a first activity plan. For more details, RIPE can be contacted at the following address: Dr.R.Blokzijl RIPE c/o NIKHEF P.O.B. 41882 NL-1009 DB Amsterdam the Netherlands phone: +31 20 5925102 fax: +31 20 5925155 e_mail: k13@nikhef.nl RIPE maintains a general electronic distribution list. Requests for inclusion in this list can be sent to: ripe-request@nic.EU.net Finally, we would like to quote from the RIPE terms of reference: "All parties operating wide area IP networks in Europe are encouraged to participate". Sincerely Yours, Rob Blokzijl RIPE Spokesman Amsterdam, 29 November 1989
