International Journal of Inactivism (now supplanted by Decoding SwiftHack)

You are in a little maze of twisting think-tanks, all different

cite as: F. Bi. You are in a little maze of twisting think-tanks, all different. Intl. J. Inact., 1:166–167

I’m now convinced that the walls of the Internet maze of free-market think-tanks are wrought with magic, because they’re starting to look like Escher’s paintings of impossible constructions. Consider these:

  • Doing a reverse lookup of the IP address 198.161.91.113 yields the canonical domain name secure.acton.org. However, doing a forward lookup on secure.acton.org yields a different IP — 198.161.91.164.
  • 198.161.91.138 resolves to mail.fcpp.org, which in turn resolves to 64.201.170.131.
  • 198.161.91.202 resolves to http://www.fraserinstitute.ca, the name of the Fraser Institute web site. This name resolves to 64.40.117.99.
  • 198.161.91.203 resolves to http://www.childrenfirstgrants.ca, which resolves to 198.161.90.18 (Nexus Tennessiæ).

Now, 198.161.91.202 and 198.161.91.203 don’t seem to have anything. However, the web page http://198.161.91.113/ gives something interesting:

I don’t know what a web site for the Atlas Foundation is doing on a server whose canonical name belongs to the Acton Institute… but their membership directory is probably worth checking out.

And finally, the URL http://198.161.91.138/ leads to a sort of login-only area for the FCPP.

  1. There is no requirement a forward (name-to-address) mapping corresponds 1 to 1 to a reverse (address-to-name) mapping. In fact, with virtual web hosting, it’s actually a bad idea. If you have (say) 100 virtual hosts hanging off one IP address and you try to put those virtual host names into the reverse mapping, you will get back all 100 names when you query for the address. This has a bunch of negative effects, not least of which is the program doing the reverse lookup has to pick one of the 100 to display.

    A better way of figuring out the Internet service/hosting provider is to use “whois” (almost certainly to whois.arin.net, that is, on a Unix-based system “whois -h whois.arin.net 198.161.91.138).

    Hope this helps,

  2. There is no requirement a forward (name-to-address) mapping corresponds 1 to 1 to a reverse (address-to-name) mapping.

    That I know, but the odd thing about what I found is that the mappings don’t correspond at all. I suspect that some of the bogus reverse mappings are detritus from earlier times when the named web sites were indeed hosted at those addresses: e.g. webhosting.info’s reverse lookup service shows that 198.161.91.202 corresponds to canstats.org and canstats.com, a project which was under the Fraser Institute (but now probably moribund).

    Thanks anyway. 🙂
