Dear Colleagues,
The RIPE NCC received the IPv4 address ranges 77.0.0.0/8 and 78.0.0.0/7
from the IANA in August 2006. We will begin allocating from these ranges
in the near future.
The minimum allocation size for these four /8s has been set at /21. 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:
https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html
Additionally, please note that two "pilot" prefixes are being announced
from each /8. Details of the prefixes, 'pingable' target names and
addresses for each prefix can be found on our web site at:
http://www.ris.ripe.net/debogon/debogon.html
Best regards,

Dear Colleagues
The RIPE NCC Training Services Department invites you to register for one
of our upcoming Routing Registry Training Courses:
Date: Friday 1 September 2006
Time: 0900 - 1700
Location: Reykjavik, Iceland
AND
Date: Thursday 26 October 2006
Time: 0900 - 1700
Location: London, United Kingdom
AND
Date: Friday 4 November 2006
Time: 0900 - 1700
Location: Amsterdam, Netherlands
AND
Date: Monday 27 November 2006
Time: 0900 - 1700
Location: Rome, Italy
Hosted by: CASPUR http://www.caspur.it/
Hosted by: NAMEX http://www.namex.it/
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 course is free of charge. We provide lunch and printed training materials.
We do not cover any of your travel expenses or accommodation.
We give all of our training courses in English.
You can find more information about the course at:
http://www.ripe.net/training/rr/
How to register:
---------------------
You can register up to two people from your LIR for each course.
(If there are places left nearer the time of the course, you can register more people).
To register for this course, you can either use the LIR Portal at:
https://lirportal.ripe.net/lirportal/training/course-list.html
Or the online registration form on our website:
http://www.ripe.net/cgi-bin/trainingform.pl.cgi
If you have any questions, send an e-mail to <training(a)ripe.net>.
