Dear Akamai, you got a /32 there not a bunch of /48s - how to break Facebook and annoy lots of users

Sorry, just had to reply, this section of your email is
brilliant!!! Shame I can't convince my bosses the only way forward is
distributed content....

falling. Of course, it is important to not waste slots needlessly, or
otherwise be silly with a limited resource. But The End is not nigh.

to manage the growth of things like VoD is massive distribution of
content. Everyone who has a _LOT_ of traffic is following in Akamai's
footsteps by placing non-network connected caches inside broadband
networks. Assuming ISPs treat content providers alike, you will see this
problem with many content companies.

perspective, 1 in 5 bits on most broadband modems worldwide come from an
Akamai server. Google has similar traffic, NetFlix has a lot of traffic
in the US and a non-trivial amount in other countries, etc. It seems
more than obvious to me the real danger is creating obstacles to
distributing traffic more widely, not whether we have a few thousand
more or even a couple orders of magnitude more prefixes in the v6 DFZ.

Regarding the Subject line: Jeroen, we have different definitions of
"lots of users".
