With the transition from IPv4 to IPv6 becoming ever more important
due to the likely exhaustion of IPv4 addresses in mid-2011, a guru on
the topic, Geoff Huston, has written about some of the transition myths.
Myths covered by Huston in his posting with brief excerpts to his responses are:
- We have many years for the transition to IPv6 - No!
- "Its just a change of a protocol code. Users won't see any difference in the transition." - If only that were true!
- "NAT upon NAT upon NAT will work" - Maybe
- "Changing the Customer Premises Equipment (CPE) is easy" - No, not necessarily.
- "My ISP has enough IPv4 addresses to last for years, so they don't have a problem" - Well, not necessarily
- "We will always have to run IPv4 protocols" - Probably not
- "There is a technology that will translate between IPv4 to IPv6" - Yes, but.
- "We don't necessarily have to transition to IPv6. There are substitutes." - Nothing is visible from here!
- "We know what's happening" - I'm not sure that's universally true!
- "We know what we're doing" - Individually this is, hopefully true
- "We have a plan!" - See above.
- "The Internet will be fine!" - I'm unsure about this one.
- "The incumbents will have all the IPv4 space. Thanks for playing." - If that's not a myth, then we are going to be in serious trouble!
