My first reply to this thread. I've been kind of tracking it. I would love to move to IPv6. However, the IPv6 addressing, I have to say, is really tough to remember and understand for most people. Where is a four number dotted quad was easy to remember, an IPv6 address.. not so much. I wished they had made that a little easier when they were drafting up the protocol specs. basically, you need technical knowledge to even understand how the IP address is split up. I wished ARIN would waive the fee for service provider's first block of IPv6 as well. It would help make the dual stack deployment easier.
I know IPv4 is running out. I understand the situation. I just wished they had put a little more thought into the user experience side of the addressing. You can all flog me now if you want. I expect it. I'm green on IPv6. I would love the education if I am wrong. -S Mark Newton wrote: > On 06/03/2010, at 1:06 AM, David Conrad wrote: > >> Mark, >> >> On Mar 4, 2010, at 11:46 PM, Mark Newton wrote: >>> On 05/03/2010, at 2:50 PM, David Conrad wrote: >>>> When the IPv4 free pool is exhausted, I have a sneaking suspicion you'll >>>> quickly find that reclaiming pretty much any IPv4 space will quickly >>>> become worth the effort. >>> Only to the extent that the cost of IPv6 migration exceeds the cost >>> of recovering space. >> You're remembering to include the cost of migrating both sides, for all >> combinations of sides interested in communicating, right?
