I agree that IXPs would be very gould locations as they offer network diversity, but there is one question still open and that is who will be the one running the and monitoring the server. And we at DENIC have seen in the last years an increasing demand in running the servics by ourself as only then we have the complete control and information about statistics, network attacks, performance ... There is a project within CENTR where we try to share secondary services on one host with the advantage for all geting these informations.

KPNQwest ns.eu.net server.
by Daniel Diaz 06 Jun '02

06 Jun '02

Dear all, Given the current situation of KPNQwest and the possibility of its services going offline sometime soon, the RIPE NCC in agreement with KPNQwest will be temporally hosting this server (ns.eu.net) in its premises. This is to avoid major problems in the Internet as this server is secondary for a large number of ccTLD's zones, and thousand other zones. We (AS3333) will be soon announcing the 192.16.202.0/24 prefix. Trusting that this is welcome news. Best regards. -- RIPE NCC -- Daniel.Diaz Operations Manager RIPE NCC

Hello, DENIC runs currently several secondarys (not only DE but also for some other TLDs) in different places worldwide. We are willing to offer secondary service for other ccTLDs. But there will be because of security/stability reasons a limit on the number of ccTLDs we want to run on a single machine.

Hi Randy, hi Joao, dear routing-wg, probably my Company (GATEL, AS13129) is able to host a secondary server for the ccTLDs. The question is rather what are the hardware "requirements" for the secondary server. We have sufficient bandwidth capacity available and rack space as well. > The rest can take bit more time to think what they want to do since > ns.eu.net will keep running. Well done !

Dear Colleagues, The RIPE NCC received the IPv6 address range 2001:0800::/23 from the IANA in May 2002. 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 Assistant Manager

The Cidr Report

This is an auto-generated mail on Fri May 31 23:00:01 PDT 2002 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amount of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes.

The Cidr Report

25 May '02

This is an auto-generated mail on Fri May 24 23:00:00 PDT 2002 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to GX Networks for giving me access to their routing tables once a day.

This is an auto-generated mail on Fri May 17 23:00:00 PDT 2002 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. Check http://www.employees.org/~tbates/cidr-report.html for a daily update of this report. NEW: Check http://www.employees.org/~tbates/cidr-report-region.html for the regional version of this report. NEW: Check http://www.employees.org/~tbates/autnums.html for a complete list of autonomous system number to name mappings as used by the CIDR-Report. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to GX Networks for giving me access to their routing tables once a day. Please send any comments about this report directly to CIDR Report <cidr-report(a)cisco.com>. ------------------------------------------------------------------------------ CIDR REPORT for 17May02 0) General Status Table History ------------- Date Prefixes 100402 108550 110402 108701 120502 109917 130502 109712 140502 109853 150502 109940 160502 109828 170502 109785 Check http://www.employees.org/~tbates/cidr.plot.html for a plot of the table history.
