When I suggest to my customers to move to IPv6, I explicitly tell them that planning is very important: 1) Initially (in some cases), your equipment may not have native support for the core/access networks. Not a problem, when you upgrade your network for other reasons (line cards, new IPv4 features, etc.), IPv6 usually will come as a value added. At the time being a transition box (event just a PC), could make it, as the traffic levels are low. This also give you the time to experiment, see how the traffic is growing, and help your "commercial" decision to move ahead faster or not. 2) Same with the CPEs. They don't support today, most of the time, native IPv6, but a PC in your network, probably with 6to4 and Teredo as non-managed transition mechanisms, will do it. Is not the optimal way, but help to move on but better than just nothing. Doing this you offer better service to your customers who are also playing with IPv6, instead of asking them to use third party tunnel brokers or 6to4 relays. Of course, a better service could be to setup a TB in your network, but this could mean some extra O&M cost. If you network is big, obviously you may need to setup several of those PCs, in different POPs, regions, etc. but you will see the need when traffic comes. The alternative is also to use existing or old routers, which most of the time also support 6to4. Regards, Jordi

agreed, it's a measured engineered decision hopefully. backed by financial and prudent engineering decisions. that wasn't the tone of the orignial comment though, which was: "Yea, I told them to just do it" which is tantamount to 'forklift your network you dummies'.
For some equipment, it still works out to "forklift your network". For example, our current dialup gear doesn't support IPv6 (and AFAIK no upgrades are available or planned to add it). There's no reason for us to replace our dialup gear; the only thing that fails on it is fans (and we can replace those easily enough with an hour's work of chassis dis/re-assembly). Dialup isn't going to go away in the near future either.
i suspect there is quite a large amount of gear (type not weight) that will never see v6 through the vendors but still support customers... speedstream anyone? cable-modem anyone? :( there are LOTS of things out there that don't know from v6 :(
Thanks for another example though :)
