   Format: MarkdownIt looks like the IP is being improperly blocked, then. My machine is connected through my parents' wireless LAN, which gets a dynamic IP address from their phone company. When I go to <http://www.whatismyip.com/>, it lists today's address as 173.190.145.192 (the same one that you, Andrew, found in the logs and reported to me by email). When I [look that up at spamhaus](http://www.spamhaus.org/query/bl?ip=173.190.145.192), they direct me to the CBL. The CBL's [instructions for those with a dynamic IP address](http://cbl.abuseat.org/dynamic.html) are to ensure that no email is sent from that address. Of course, none ever is! But Instiki is not using the CBL to block email, but for something else. The CBL people [say about that](http://cbl.abuseat.org/nonmail.html) that they "do not discourage" such use, although that is not what it is designed for, and I should talk to "the provider of the service you're trying to use", which is what I'm doing here. They seem to think that we should put my address in as an exception, although that doesn't seem very useful for a dynamic address. (Although if it's something that I can do myself, then I can just keep track of it in real time.) Or I can [lie to the CBL](http://cbl.abuseat.org/removeX.cgi?ip=173.190.145.192), claim that I've fixed the problem (which is probably that somebody else using Windstream has an infected computer, which I cannot fix), and get them to delist the address. That will work until the next time Windstream assigns an address that was previously used by the infected customer, or until enough people do this that the CBL stops believing it. I can't change my parents' IP address at will, since my dad's machine (over which I have no control, unless I go so far as to unplug it, although probably I could find the wireless router and just unplug that) is always up and nominally using the address. However, Windstream does seem to reassign the address every day or so regardless, so if nothing else works then I will just have to wait, and hope that the next address has not been used by the infected customer first. (There is also the possibility that my dad's machine is infected, of course, although he is a sysadmin by profession, so that *shouldn't* be the case. I can ask him tonight what the odds are of that.) As for VPNs, I just checked, and I don't have access to those of my former schools. I would do that if I could.
