Generating EUID IPv6 address from a MAC

When you set up radvd (router advertisement daemon) on a network, all the computers that support IPv6 will adopt addresses in the advertised address space – except the machine that actually advertises the address prefix (thr router, if you will). You can assign an address to the interface yourself, any address will do. For instance, […]

MAT WG

Some notes from the MAT working group  at RIPE64 Measuring networks in Norway Networks are critical infrastructure A signaling storm in a Norwegian mobile provider coincided with bad flooding in real life, causing very bad public feeling about the reliability of emergency handling. So a number of operators are focusing on measurements, both in academia […]

IPV6 working group

Notes from a bunch of presentations given at RIPE64 Swedish post and Telecom work with IPv6 In Sweden, (since 1600s) ministries are weak, overseeing authorities, and agencies rule, particularly during emergencies. Ministries can not give agencies instructions on operational matters. PTS is the telecommunications regulator (telephony, broadband, postal services). PTS deployed IPv6 internally since 2009. […]

Form IPv6 day to IPv6 launch and how it is different

Based on a lecture at #ripe64 8th June 2011 is the kick-off date, leading content providers will turn on IPv6 and keep it on. IPv6 day broke the chicken and egg problem, and it provided a target date for some of the deployments. Practically no problems happened, which is terrific, but overall traffic was low. IPv6 […]

Dual stack behaviour and IPv6 quality

(based on lecture at #ripe64 ) Is life better with two protocols than it is with one? No, network operators and browser guys managed to stuff it up. Dual stack v1: unconditional preference for IPv6: if the IPv6 did not get a response, everything was very slow. The problem were the auto-tunel techniques (6to4 and […]
