The simple answer is *DNS*. I don't email or web browse to numerical IP addresses. Nor does any of my internal systems connect to services by IP addresses. They all use DNS. I learnt, long ago, that IPs will often change, or need to change, as the topology of a network gets re-arranged. But when you use domain names, your mail server is always mail.example.com, and none of the clients need reconfiguring to accommodate system admins rearranging the computing furniture. Services change hosts all the time, and other than for a transition period, nobody outside of the people configuring the service are aware of any change. And this is the situation for IPv4 and IPv6. Likewise, clients change IPs all the time, thanks to widespread implementation of DHCP as an easy solution for central management, and various sysadmins not caring whether the same IPs get reassigned to the same clients, or reaching the conclusion that it doesn't really matter. Only the pathologically obsessive really care whether the IP for example.com is the same this year as last year. Likewise for other domain names. On the other hand, IPv6 could be a godsend for spam filtering, or other malicious internet use. If all the hosts involved have real IPs rather than non-unique private addresses, it becomes easier to blacklist them and the providers which allow them. -- [tim@localhost ~]$ uname -r 2.6.30.10-105.2.23.fc11.i686.PAE Don't send private replies to my address, the mailbox is ignored.
