Especially given the size of the 10.0.0.0/8, I cannot for the life of me imagine an organization needing more. Even if one were to divide on the basis of the old class C, that leaves upwards of 65,000 possible subnets with which to play. </FONT></P>
<P><FONT SIZE=2>I haven`t see the above mentioned here.</FONT>

<P><FONT SIZE=2>I only mentioned non-routable to address the routing table size</FONT>

<P><FONT SIZE=2>CompanyA and CompanyB, each having their own autonomy, are using private</FONT>

<BR><FONT SIZE=2>independently to the internet via their ISP of choice with public space</FONT>
<BR><FONT SIZE=2>provided by their ISP. Both companies wish to connect to each other</FONT>
<BR><FONT SIZE=2>directly (not through the internet). Since there is a conflict in IP</FONT>
<BR><FONT SIZE=2>addresses, NAT with public IP addresses is necessary. CompanyB insists</FONT>
<BR><FONT SIZE=2>that CompanyA use public address space (internet routable or otherwise;</FONT>
<BR><FONT SIZE=2>neither Company cares).</FONT>
</P>
<P><FONT SIZE=2>CompanyA needs about 100 distinct public IP addresses (to start anyway).</FONT>
<BR><FONT SIZE=2>To the best of my knowledge and experience, there is currently no way to</FONT>
<BR><FONT SIZE=2>get a non-routable or routable public /24 to satisfy these requirements.</FONT>
<BR><FONT SIZE=2>ISPs claim CompanyA cannot justify, based on ARIN policy, more address</FONT>
