The internet first said "lo" like in 'lo and belold, I exist', but in reality it was the first three letters of "log". the whole system crashed when they typed the "g". That was 1969: http://www.lk.cs.ucla.edu/personal_history.html As far as packet radio (I'm from Hawaii, so I really like this one) Professor Norman Abramson developed ALOHAnet (packet radio) in 1970 at the University of Hawaii, which became the core idea for Robert Metcalfe's CSMA and, thus, Ethernet: https://en.wikipedia.org/wiki/Packet_radio#Aloha_and_PRNET One of my favorites is the letter from R.Z.

peering request

by Julien Sansonnens

Hello, Zaledia.com is a small not-for-profit organisation. We are a group of some interested technicians, IP networks enthusiasts. We like development and open protocols. We operate AS207149, and provide IPv6 connectivity to our users, with a goal of sharing knowledge and development of a free internet, decentralized and neutral. We don't have the money yet to obtain native IPv6 connectivity from some datacenter, so we receive it via a tunnel from Hurricane electric. We are looking for some good souls that would agree to provide us IPv6 transit graciously, as a sponsor. Traffic to and from our network is extremely small, if not insignificant. We would like to get one or two transit upstreams to ensure some redundancy in providing connectivity. We propose a BGP session via 6to4 or OpenVPN tunnel, preferably. If you do not want to transit, we are also interested to peer with any interested organization. Cordial greetings, Julien Sansonnens Zaledia.com

RFC 1918 usage in Internet routes - was: Re: Swinog Post RFC1918 IP's on BBCS and Cable based Services

by Stephan Wolf

Hello Sunrise, many thanks for your (anonymous) feedback. <Offtopic> Ok, I have not seen this other discussion - and simply I do NOT want to start this "relegious" discussion about it. For me personally it is "bad behaviour" to use RFC1918 in internet public based services / routes. For sure others CAN do, because it is not strictly forbidden. This is for me also a general "problem" according RFC's: what is "MUST" and what is "SHOULD".... So I stop it here. </Offtopic> Back to my case: Here see the traces which use RFC1918 in your backbone. So you assign it ! Or may send me an introduction why I am wrong. May I missed something. Many thanks in advance, Best Regards Stephan remark: 192.168.12.254 is your CPE / Fritzbox /root: traceroute local.ch traceroute to local.ch (185.101.119.163), 64 hops max, 40 byte packets 1 192.168.12.254 (192.168.12.254) 0.826 ms 0.650 ms 0.559 ms 2 10.136.71.241 (10.136.71.241) 18.020 ms 18.421 ms 18.051 ms 3 172.16.19.146 (172.16.19.146) 22.824 ms 22.594 ms 20.392 ms 4 172.16.19.145 (172.16.19.145) 20.397 ms 23.046 ms 22.561 ms 5 194.230.108.185 (194.230.108.185) 18.058 ms 19.911 ms 19.526 ms 6 * * * 7 * * * 8 oer02pe05.ge1-0-19.bb.sunrise.net (212.161.250.138) 20.847 ms oer02pe05.ge1-0-0.bb.sunrise.net (212.161.250.134) 22.801 ms 22.368 ms 9 195.141.229.234 (195.141.229.234) 22.636 ms 22.517 ms 22.724 ms 10 * * * 11 * * * (snip) /root: traceroute -I local.ch traceroute to local.ch (185.101.119.163), 64 hops max, 48 byte packets 1 192.168.12.254 (192.168.12.254) 0.682 ms 0.543 ms 0.506 ms 2 10.136.71.241 (10.136.71.241) 18.382 ms 20.533 ms 17.602 ms 3 172.16.19.146 (172.16.19.146) 22.372 ms 22.011 ms 22.478 ms 4 172.16.19.145 (172.16.19.145) 21.672 ms 21.664 ms 22.113 ms 5 194.230.108.185 (194.230.108.185) 19.564 ms 19.532 ms 19.533 ms 6 * * * 7 * * * 8 oer02pe05.ge1-0-19.bb.sunrise.net (212.161.250.138) 22.131 ms 22.230 ms 21.965 ms 9 195.141.229.234 (195.141.229.234) 21.793 ms 22.007 ms 21.611 ms 10 * * * 11 * * * (snip) >tracert local.ch Routenverfolgung zu local.ch [185.101.119.163] über maximal 30 Hops: 1 <1 ms <1 ms 1 ms 192.168.12.254 2 18 ms 17 ms 18 ms 10.136.71.241 3 23 ms 22 ms 22 ms 172.16.19.146 4 23 ms 23 ms 22 ms 172.16.19.145 5 24 ms 20 ms 20 ms 194.230.108.185 6 * * * Zeitüberschreitung der Anforderung. 7 * * * Zeitüberschreitung der Anforderung. 8 87 ms 85 ms 83 ms oer02pe05.ge1-0-19.bb.sunrise.net [212.161.250.138] 9 87 ms 86 ms 79 ms 195.141.229.234 10 * * * Zeitüberschreitung der Anforderung. 11 * * * Zeitüberschreitung der Anforderung.

Bad Connectivity at UPC Home Internet

by Tobias Brunner

Hi all, I'm having a hard time with my UPC Internet at home. Connections to f.e. Github are nearly impossible since a few weeks (can't remember exactly since when =( ), but when connecting through a VPN (exits at AS57118) there are no performance issues other connection problems. This connection troubles are not only to Github, but also to other random destinations like Ifolor, sometimes Google, sometimes SRF, ... I couldn't find patterns at the moment, SmokePing started collecting them for me =) (currently it shows huge paketloss, but still have to wait some more days for better graphs). Is anyone else having such issues with UPC home Internet? Cheers, Tobias

'known' DNS Problems with Migros Banking App?

by Benoit Panizzon

Hello One customer contacted us, because the Migros Banking App does not work from within our network and asked me to contact the Migros NOC to find out what we should change to make it work. From the Migros NOC I got the feedback, that this is an issue they observed with customers whose ISP have IPv6 enabled DNS Server. They recommend that either the ISP disables IPv6 on the nameservers, or that the customers uses a different ISP, for example via Mobile Phone Hotspot to use their Banking app. Apparently UPC Cablecom is another ISP with the same issue and cablecom is able to resolve the issue by disabling IPv6 for the affected customers. I am a bit puzzled. I first suspected a DNSSEC issue as our servers do validate DNSSEC. But this does not seem to be the case. I can resolve the hostnames without any problems via our DNS Servers. Our DNS Servers are IPv6 enabled. When another DNS Server has an IPv6 address, they will prefer IPv6. But our customer does not get an IPv6 address. So his local resolver does only know the IPv4 address of our DNS Servers. The Migros DNS Servers do not publish an IPv6 address. So how is IPv6 involved in this issue? The Domain in Question: mbmid.ch is: mbmid.ch. 241 IN NS ns1.datacenter-migros.ch. mbmid.ch. 241 IN NS migze104.migros.ch. mbmid.ch. 241 IN NS migze100.migros.ch. ns1.datacenter-migros.ch. 146 IN A 164.14.130.66 migze100.migros.ch. 3222 IN A 146.67.146.20 migze104.migros.ch. 3222 IN A 193.8.177.201 They are not DNSSEC Signed. The only issue I found is that ns1.datacenter-migros.ch is not published in the registrar glue record, but this also would not lead to a failure to resolve the hostname. Has anyone else come across that issue and could give me a hint where to further investigate? -Benoît Panizzon- -- I m p r o W a r e A G - Leiter Commerce Kunden ______________________________________________________ Zurlindenstrasse 29 Tel +41 61 826 93 00 CH-4133 Pratteln Fax +41 61 826 93 01 Schweiz Web http://www.imp.ch ______________________________________________________
