<br>
And, given that I can get IPv4 for the same price, why go to the hassle<br>
of doing anything with IPv6? The business case for doing new things<br>
with IPv6 should include "and the address space is essentially free,so<br>
we wilkl do the network architecture correctly, rather than creating a<br>
hack that supported IPv4 NAT/bridging"<br>
<br>
Do you know how many layer-2 **hack** have been created because IPv4<br>
subnets are a fixed quantity? (particularly in the pre-CIDR days)<br>
<br>
IPv6 allocations and especially end-user assignments, need to be<br>
essentially free. In the IPv4 time scale, this is 1989, when<br>
enterprises just came to the table for address space, with *no<br>
intention* of advertising that space.<br>
