With the 4 byte address there is partitioning of the address between countries, RIRs, service providers, companies, networks, sites, and finally resolving to a node. By adding to the address space it allows for "mobile" ip addresses. The same ip address at work also works at home regardless of who or what the ISP is.<br></span></div><div><span></span></div><div> </div><div><span style="font-family:courier;">--- </span><br style="font-family:courier;"><span style="font-family:courier;">Wayne Johnson, | <span style="color:rgb(191, 95, 0);">There are two kinds of people: Those</span> </span><br style="font-family:courier;"><span

<br><br>8 bytes is a huge increase. IPv4 has lasted longer than expected <br>so I can't imagine 8 bytes being exhausted in the future. I read that <br>16 byte addresses can address more atoms than are thought to exist.<br>
From a practical point of view I think the 16 byte addresses are<br>a mistake. Systems have to work through all of that before they<br>can start to do something useful. That's a good reason not to <br>switch to IPv6. I believe you about IPv6 being an improvement <br>
over IPv4 in a number of ways, but think the length of the addresses <br>was a mistake.<br><br>I don't think anyone is paying for IPv6 specific upgrades to hardware.<br>When they upgrade for a practical reason, the hardware they get is <br>
more IPv6 capable than what they had.<br><br><br><br>Brian Wood<br>Ebenezer Enterprises<br>http://webEbenezer.net<br>(651) 251-9384<br><br><br><br><br>
