That is good.  But also obviously if one is done the other is not needed.

I thought both were specific to IPv6.

I am not going then to ask why NETEXT is doing what is doing, neither v6ops.

But it is surprising these two alternatives realize the same 
functionality.  Whether you want to agree to this or not is another 
matter :-)
