Sorry, I assumed it would be obvious that I obscured the real addresses (since this is a public list, and the addresses are not private ones). > > But, having the IPv6 unconfigured isn't too surprising, since very few > ISPs seem to route it.

For most of these links, Firefox ends up reporting "Problem loading page". Yet one of the links there tell me I am coming in via IPv6, but the address they claim I am using is very different than the one shown to me by ifconfig. ifconfig says: fe80::2e0:4dff:ffff:ffff/64 (last two segments intentionally obscured) They say: What Internet Protocol am I using? You are using IPv6 and are coming from 2001:7b8:3:4f:202:b3ff:ffff:fff <http://www.sixxs.net/tools/ipv6calc/>. You can use the IPv6Gate <http://ipv6gate.sixxs.net/#ipv6gate> to browse IPv4 websites without any configuration changes or without having to install any additional software. (I obscured the actual address. If important, ask me.) And when I click on the link that is supposedly my IPv6 address (according to them), it takes me to a page with the following: Your client IPv4 address 68.183.ff.ff <http://www.sixxs.net/tools/whois/?68.183.60.254> (actual info obscured) Registry of IPv4 address ARIN Reverse DNS resolution netblock-68-183-ff-ff.dslextreme.com.

Our destruction, should it come at all, will be from another quarter, from the inattention of the people to the concerns of their government. From their carelessness and negligence, I must confess that I do apprehend some danger. I fear that they may place too implicit a confidence in their public servants and fail properly to scrutinize their conduct, that in this way they may be made the dupes of designing men, and may become the instruments of their own undoing. Make them intelligent, and they will be vigilant. Give them the means of detecting the wrong and they will apply the remedy. --Daniel Webster -- KPLUG-LPSG@kernel-panic.org http://www.kernel-panic.org/cgi-bin/mailman/listinfo/kplug-lpsg
