New IPv4 blocks allocated to RIPE NCC
by leo vegoda 18 Nov '03

18 Nov '03

Dear Colleagues, The RIPE NCC received the IPv4 address ranges 83.0.0.0/8 and 84.0.0.0/8 from the IANA in November 2003. We will begin allocating from these ranges in the near future. On 24 October 2003 there was a formal proposal to the RIPE Address Policy Working Group to lower the minimum allocation size from /20 to /21. For the text of this proposal please see: <http://www.ripe.net/ripe/mail-archives/address-policy-wg/2003/msg00189.html> It is likely that there will be formal consensus on this proposal in the near future. Consequently, the minimum allocation size for these blocks has been set at /21. Nonetheless, the RIPE NCC will not make /21 allocations from these blocks until after there is formal consensus to do so. You may wish to adjust any filters you have in place accordingly. More information on the IP space administered by the RIPE NCC can be found on our web site at: <http://www.ripe.net/ripe/docs/smallest-alloc-sizes.html> Kind regards, -- leo vegoda RIPE NCC Registration Services Manager

Announcement Routing Registry Training Courses
by RIPE NCC Training 13 Nov '03

13 Nov '03

------- Dear Colleagues, [apologies for duplicate postings] As a service to its members the RIPE NCC offers the "Routing Registry Training Course". The main objective of the "Routing Registry Training Course" is to familiarise the LIRs with the features of the Routing Registry, while introducing the relevant tools and services of the RIPE NCC. The course also offers practical exercises. OVERVIEW OF TOPICS COVERED IN THE COURSE: - Routing Registry as a part of the RIPE Whois Database and the Internet Routing Registry (IRR) - Specifying routing policies using (RPSL) Routing Policy Specification Language and the RtConfig tool - IRRToolSet - Routing Information Service (RIS) - Routing Registry Consistency Check Project Please note that this is an advanced course. It will: - NOT teach the basics of routing - NOT teach the basics of RIPE Database operations, - NOT describe how to receive Internet resources from the RIPE NCC - NOT describe how to operate a Local Internet Registry (LIR) The target audience of the course are technical staff of LIRs: e.g. network operators, engineers etc. This course is not intended for administrative or management staff (e.g. Hostmasters) . It is assumed that all attendees will be familiar with Border Gateway Protocol routing and with the RIPE Database (i.e. creating/modifying objects). This course is based on interactive exercises in a local network set-up. Please bring your laptops equipped with the following: - A working Ethernet card, - Three meters of Ethernet cable, - A secure connection client, - A web browser. Please be prepared to share your laptop (or at least allow another attendee to "look over your shoulder") if necessary. The Routing Registry Training Course is conducted in the English language and is free of charge, since it is covered by the membership fee. More information about the Routing Registry Training Course can be found at: http://www.ripe.net/training/rr/ REGISTRATION: You can register for a Routing Registry Training Course at the following URL: http://www.ripe.net/cgi-bin/trainingform.pl.cgi Or by completing the registration form at the end of this e-mail and replying to <training(a)ripe.net> . In order to register for a Routing Registry Training Course you must be an employee of an LIR and either: - be an LIR contact - be confirmed by an LIR contact LIR contacts are those employees of an LIR who are registered with RIPE NCC as authoritative contact persons.
