One could understand application programmers falling into the traps of IPv6 myths, but when it happens to Cisco’s Global PR Manager, it’s embarrassing. Marc Musgrove was promoting at least one and a half myths (I’m still not sure about easier mobility with IPv6) in his latest blog post.
Simplified packet header for routing efficiency. This is a new one for me (and I thought I’ve seen them all), but no less bogus than any other. Cisco’s own measurements confirm that IPv6 performs almost equally well (or marginally worse) than IPv4. There’s no improvement and no increased efficiency.
Mandatory IPSec implementation for all IPv6 devices. While this is technically true, it’s at least misleading, as most readers automatically assume it means any host-to-host communication can be easily encrypted. Not necessarily true, you’ve implemented a compliant IPSec implementation even if you just recognize the IPSec header without having any ESP (encryption) or AH (integrity/origin authentication) capabilities.
Maybe it’s time we all grow up and admit the only benefit of IPv6 is its larger address space.
