Well this is strange. Yesterday when I searched for the IP 218.86.217.58 I got the posting I got the information I listed in Post #3 above. I just wrote here that this was not the same as the one posted by Shub-Nigurrath:
218.86.
128.0 - 218.86.
255.255
but when I checked the original IP again I got the same information Shub-Nigurrath posted. I thought I had copied and pasted the original IP into the search engine, but I apparently did something wrong, because it is clearly from China, and not Australia.
However, I do not believe it would be a good idea to attempt to ban as wide a range of IPs using the C component (rather than the D component), since it would effectively ban the entire Guizhou province.
Aaron's IP might even be from that group, I haven't checked recently. Then we'd all be in trouble.
It would be a GOOD IDEA to tighten up the security of your passwords, both here and on your email.
