As Steve Gibson said in last "security now" podcast, almost all current network equipment is not working with IPv6 packets for now. Is that really the case ?
Edit from initial post: Hub and switches are working on level 2 and so, not concerned.
If so, do you think manufacturer (like Cisco, Netgears, 3Com and so on) will release firmware update to upgrade them to fix that issue ? Or will they tell us to buy new stuff ?
Also, by the way, as IPv6 are much bigger than IPv4 address, will upgraded network equipment performance be much slower than with IPv4 (because addresses cache will contains less IPv6 address than IPv4 ones, and cos more processing power will surely be necessary to process packet) ?
I know IPv6 is not really needed inside a LAN today (because NAT is working great) but I would have your opinions on that subject.
