The thing about TCAM memory is that it can be big killer for IPv6 migration. Why ?
Some discussion on why allocating a /64 is not wasteful
I posted yesterday about changes to RFC3177 for IPv6 allocation. I wonder how many have done the maths on this and realised just how many addresses this works out to be. Lets hold hands and work through the maths: Lets say you are allocated a /48 by your favourite RIR. Lets also say you allocate […]
The whisper is that the last two /8 IP address ranges were today allocated. Since there were seven pools of /8 addresses, this means that we are witnessing the start of the IPocalypse. What’s Happened ? Some time ago, Internet Assigned Numbers Authority (IANA) established the final process as the IPv4 address pool is exhausted. […]
IETF is now backtracking on /48 IPv6 address allocation by letting anyone do what the hell they like. Why not ?
Ivan Pepelnjak has made a presentation available at [Slideshare – Content over IPv6 – No Excuses]. One slide particularly caught my attention: It’s timely reminder that the IPocalypse is going happen quite slowly. Each step is inevitable but none of the them are the final step. For example, once the IANA runs out of addresses, […]
Collection of useful, relevant or inane places on the the Internets for 6 Oct 10:
This week on the Packet Pushers podcast, Greg and Ethan continue an IPv6 technical deep-dive with Matt Ryanczak, Network Operations Manager at ARIN (where they’ve been running IPv6 since 2003) and Jan Bervar from NIL who has done several enterprise IPv6 deployments.
At last, some decent rules on the RIGHT way to write IPv6 addresses.
