<P><FONT SIZE=2>ARIN has no control over the deployment of any IPvN. ARIN must assume</FONT>
<BR><FONT SIZE=2>that IPv4 is here for the foreseeable future. ARIN`s policies must</FONT>
<BR><FONT SIZE=2>not rely on any replacement to the current IPv4. All my opinion of</FONT>
<BR><FONT SIZE=2>course.</FONT>

<P><FONT SIZE=2>Seems to me that ultimately the issue of IPv4 address reclamation falls out</FONT>
<BR><FONT SIZE=2>like this....</FONT>
</P>
<P><FONT SIZE=2>Question 1..... Is IPv6 really a viable protocol for widespread Internet</FONT>
<BR><FONT SIZE=2>application? If yes, then...</FONT>
</P>
<P><FONT SIZE=2>Question 2..... Is the (relatively) contiguous blocks of unallocated IPv4</FONT>
<BR><FONT SIZE=2>space sufficient to last until there is widespread adoption of IPv6? If</FONT>
<BR><FONT SIZE=2>yes, then.... Do not worry about reclamation at all.</FONT>
</P>
<P><FONT SIZE=2>If the answer to Question 1 or Question 2 is NO, then.... begin an</FONT>
<BR><FONT SIZE=2>aggressive process of voluntary reclamation, immediately (soon). Making a</FONT>
<BR><FONT SIZE=2>case for why it is in the best interests of the 'public' for such return</FONT>
<BR><FONT SIZE=2>provides the basis for litigation (involuntary reclamation) in the future if</FONT>
<BR><FONT SIZE=2>need be.</FONT>
</P>
<P><FONT SIZE=2>Oh, BTW, if IPv6 is not a viable protocol for widespread Internet</FONT>
<BR><FONT SIZE=2>application, then an aggressive process of IPv4 modification or replacement</FONT>
<BR><FONT SIZE=2>ought to be underway.</FONT>
