samples to squeeze into a low bandwidth channel. Enter IP header compression, which is shockingly effective at compressing IP headers of all sorts... if you've dedicated 128 bits for the address, and it's still just as static as it was in IPv4, it'll compress to just the same amount. This is an easy technical problem to solve.
IP header compression only works well over a link where you have few flows (fewer than the number of slots for compression) so my customers get to save some bandwidth on their access links and I get the privilege of wasting a lot in the core. But I certainly take Iljitsch's point: maybe I'm complaining about VoIP, not about IPv6. -Phil
