New IPv6 Address Block Allocated to RIPE NCC
by leo vegoda 20 Jul '05

20 Jul '05

Dear Colleagues, The RIPE NCC received the IPv6 address range 2A01:0000::/23 from the IANA in July 2005. We will begin making allocations from this block in the near future. 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 This document has been updated to to provide extra information about the IPv6 address space we manage, following some requests we received. I hope people find the new format useful. Regards, -- leo vegoda Registration Services Manager 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.

New IPv4 blocks allocated to the RIPE NCC
by Filiz Yilmaz 05 Jul '05

05 Jul '05

Dear Colleagues, The RIPE NCC received the IPv4 address ranges 89.0.0.0/8, 90.0.0.0/8 and 91.0.0.0/8 from the IANA in June 2005. We will begin allocating from these ranges in the near future. The longest prefixes to be allocated and assigned from these /8s are as follows: IPv4 Range Longest Prefix 89/8 /21 90/8 /21 91/8 /29 You may wish to adjust any filters you have in place accordingly. You can find more information on the IP space administered by the RIPE NCC on our website at: https://www.ripe.net/ripe/docs/ripe-ncc-managed-address-space.html Kind regards, -- Filiz Yilmaz RIPE NCC
