RIPE 74

RIPE 74 was held in May in Budapest, and as usual it was a meeting that mixed a diverse set of conversations and topics into a very busy week. Here are my impressions of the meeting drawn from a number of presentations that I found to be of personal interest.…


IETF 98 Report

The IETF meetings are relatively packed events lasting over a week, and it’s just not possible to attend every session. Inevitably each attendee follows their own interests and participates in Working Group sessions that are relevant and interesting to them. I do much the same when I attend IETF meetings.…


IPv6 and the DNS

The exhortations about the Internet’s prolonged transition to version 6 of the Internet Protocol continue, although after some two decades the intensity of the rhetoric has faded and, possibly surprisingly, it has been replaced by action in some notable parts of the Internet. But how do we know there is…


Labs retires the old ipv6-measurement graphs

As the stats.labs.apnic.net/ipv6 code has reached a stable service, we’ve decided to retire the old labs.apnic.net/ipv6-measurement/ tree of graphs. For people with saved URLs, it should redirect to the new service, and should map an ASN or Economy to the right dataset. For people who are farming the site for…


Binding to an IPv6 Subnet

by Joao Luis Silva Damas and Geoff Huston    In the original framework of the IP architecture, hosts had network interfaces, and network interfaces had single IP addresses. The list of active network interfaces, and the manner in which they acquire IP addresses, either by a static configuration or by…


IPv6 Performance – Revisited

Every so often I hear the claim that some service or other has deliberately chosen not to support IPv6, and the reason cited is not because of some technical issue, or some cost or business issue, but simply because the service operator is of the view that IPv6 offers an…


Fragmenting IPv6

The design of IPv6 represented a relatively conservative evolutionary step of the Internet protocol. Mostly, it’s just IPv4 with significantly larger address fields. Mostly, but not completely, as there were some changes. IPv6 changed the boot process to use auto-configuration and multicast to perform functions that were performed by ARP…


Declaring IPv6 an “Internet Standard”

I’ve already shared my thoughts following a session of the IPv4 Sunset Working Group at IETF 95 that considered whether to declare IPv4 an “Historic” specification. Of course, as one would expect for a meeting of a Standards Development Organization (SDO), that wasn’t the only standards process discussion through the…


IPv6 and the Internet of Things

It has often been claimed that IPv6 and the Internet of Things are strongly aligned, to the extent that claims are made they are mutually reliant. An Internet of Things needs the massively expanded protocol address space that only IPv6 can provide, while IPv6 needs to identify a compelling use…
