</div>I am sure some people here have already read DJBs abrasive views on the<br>
matter but if you compare the IPv4/IPv6 switch to the introduction<br>
MX records in the 80s, as he does, it seems already at that<br>
time some people were aware of workable methods for making<br>
such protocol changes be adopted quickly.<br>

The introduction of support for CIDR routes into the BGP protocol in 94<br>
might be considered another example of prior art.<br>
<br>
Sure those things are less fundamental then the layer 3 protocol.</blockquote><div><br>I think thats part of it - they are less fundemental.<br><br>Also, none of them required a complete change end to end.. in v6 you need to have user apps, user OS, access layer, backbone layer, content all enabled .. its affects all components at most layers.<br>

On the other hand, this last statement might equally well be used in<br>
support for the opposite thesis.<br>
<br>
But being wise after the fact is always easy ;)<br>
