See pub/zone/iso-country-codes on ftp.nisc.sri.com. Why does the domain count go up and down? I don't know. Do you want to count them? Are all those hosts really on the Internet? You would have to ping them to find out. If they each took 100 milliseconds to reply to a ping, you could find out in only 37 hours. How many users are on the Internet? Some people estimate around 10 per host (13 million people). If all of them were appropriately registered, the birthday-daemon would have to deliver 35,616 email messages each day. Where can I get more information? See the pub/zone directory on ftp.nisc.sri.com. ------- End of Forwarded Message

14th RIPE Meeting Audiocast
by Daniel Karrenberg 22 Jan '93

22 Jan '93

RIPE Meeting Audiocast RIPE plans to audiocast the plenary sessions of its upcoming meeting held in Prague, Czech Republic on Monday-Wednesday of next week, ie. January 25th-27th. Bandwidth to/from Prague is quite limited and no network level redundancy exists. We will use GSM encoding in order to save bandwidth. Tests done over the last few weeks indicate that this works with quite good sound quality. However, last minute problems can always force us to cancel the audiocast altogether. Anyone wishing to ask questions during the question periods is strongly advised to use GSM encoding as the conference site will not be able to understand you otherwise. Depending on network load questions over the net may not be available at all. We will be using the multicast group IETF-1-LOW-AUDIO.MCAST.NET (224.0.1.10) and base port 4100. The audiocast will be advertised conference using the LBL sd (session directory) program. Only one channel of audio will be available. For general information about the necessary software and the MBONE multicast backbone fetch the file mbone/faq.txt available from venera.isi.edu The meeting schedule is appended below. All times are central European time which at that is 6 hours ahead of EST. We are planning to audiocast at least the following sessions.

Wanted: GSM decoder SOURCE
by Guido.van.Rossum＠cwi.nl 21 Jan '93

21 Jan '93

In order to listen to audio broadcasts like the one just announced by Daniel Karrenberg I need *source* for a GSM decoder. I understand that VAT includes GSM but it seems to be available as a Sun SPARC binary only, while I can only use SGI Indigo workstations. I read the mbone FAQ but it gives no further clue. I would prefer a clean set of subroutines that do just the decoding work (so I can program the network protocol and audio user interface myself -- I can use code that I have for other encodings) but I'll take any solution that I can get working in time to listen to the Prague meeting. Of course I wouldn't mind having a GSM *coder* so I can test my decoder :-) --Guido van Rossum, CWI, Amsterdam <Guido.van.Rossum(a)cwi.nl>

RIPE NCC Quarterly Report #3 Available -------------------------------------- The third quarterly report from the RIPE NCC is now available from the RIPE document store. It details NCC activities during the third quarter of 1992. In particular it gives statistics of the European Internet Registry and the NCC information services. As always we eagerly look forward to your comments and suggestions about the report in particular and NCC activities in general. We will *not* distribute paper copies of the report at the Praha RIPE meeting in order to save some trees. As usual there will be a short presentation of NCC activities during the RIPE meeting. How to get it: The document ID is ripe-79. Gopher, WAIS and WWW users should be able to find it. FTP users can get it from host ftp.ripe.net.

Misc. Info Services and User Support items
by Jill.Foster＠newcastle.ac.uk 19 Jan '93

19 Jan '93

Unfortunately I'm unable to make the RIPE meeting at the end of this month. I wish you a fruitful meeting - particularly in the area of networked information services and user support. A couple of items you may wish to consider... The new NSFNET NIC is saying that they may charge for access to their information by non-US sites. They (amongst others) are tasked with providing a Directory of information resources. To be of any value - such a resource would depend on there being a two way flow of information between US and non-US sites in gathering together this info. I wouldn't be happy about them charging for information collected by/from us!! Several reports are available from the Mailbase Server - either via email or anonymous ftp - that may be of interest. In particular - I would like your help in updating the report on Information Sevices and User Support in Europe. Please contact me if you wish to contribute an entry for your country. Reports available: o Report IETF - Washington: Nov 16-20, 1992 (Jill Foster) o Network Training Status Report, Dec 1992 (Jill Foster) o RARE Technical Report 1: User Support and Information Services in Europe. A status report. (JF: editor) o Draft report on Networked Information Retrieval (RARE/IETF/CNI joint NIR WG) (JF: editor) To retrieve a copy, email to Mailbase(a)mailbase.ac.uk with the following command(s) as required in the body of the message: send wg-isus ietf.11.92 send wg-isus nw.training.12.92 send rare-wg3-usis rtr-usis-92 send nir consumer.report Alternatively use anonymous ftp to: mailbase.ac.uk file: pub/wg-isus/ietf.11.92 file: pub/wg-isus/nw.training.12.92 file: pub/rare-wg3-usis/rtr-usis-92 file: pub/nir/consumer.report Best wishes, Jill Foster (chair RARE Information Services and User Support Working Group)

Tony Bates Joins RARE/RIPE NCC
by Daniel Karrenberg 14 Jan '93

14 Jan '93

Tony Bates Joins RARE/RIPE NCC for two Important Technical Projects =================================================================== I am very happy to announce that Tony Bates will join RARE to work with the RIPE NCC team starting January 18th for a period of six months. Tony is a well known personality within RIPE due to his participation in many RIPE activities and his work for the UK Joint Network Team including international connections. Tony will work on two projects: "Internet Service Specification" and "Implementation of a Route Server for policy based routing across the GIX". A short description of these is appended below; Tony will present them in more detail during the Praha RIPE meeting. The projects are run in conjunction with the RARE technical programme. The main funding for the projects has been provided by SURFnet through RARE. Both projects have a tight schedule. Their success depends on the cooperation of many people within RIPE. I urge all of you to give Tony the support he will need. Daniel Karrenberg RIPE NCC Manager Internet Service Specification ------------------------------ The goal of the project is to produce a document describing all aspects of a "useful Internet service". The intention is to provide guidance to both service providers and customers. All important aspects of Internet services will be covered. This includes essential secondary aspects such as DNS service, routing protocols, routing policy features. Service providers will be able to use the document to specify the service they intend to offer. Users will be able to use it as a checklist for the services they require. The document will reference existing sources such as the relevant Internet RFCs. It is intended to give the document wide circulation including publication as RTC report, RIPE document and/or RFC as appropriate. Implementation of a Route Server for policy based routing across the GIX ------------------------------------------------------------------------ The goal of this project is to produce a functioning route server (RS) as specified in "Internet Routing in a Multi Provider, Multi Path Open Environment" by Bates, Karrenberg, Lothberg, Stockman and Terpstra. The function of the RS will be to present unified routes to European destinations to routers on the GIX. The results of the project are: - refining the specifications on routing policy information storage in the RIPE database - route server software - software to derive route server configuration information from the RIPE database - a technical report describing the above This project requires close coordination with the RIPE NCC for the database related aspects and with the operators of transatlantic links, especially EBONE. The resulting software components should be realised with generalisation of the route server concept in mind. The results will be publicly available. It is intended to give the resulting documents wide circulation including publication as an RTC report, RIPE document and/or RFC as appropriate. ----- End of Forwarded Message
