Theory Concept
The filenames are very unusual. All numeric 8.3 format (the original DOS standard). However, if you ignore the ., then you can consider it as an 11 digit number.
All the numbers begin with 0, and IP addresses in NTOA encoding look like a 10 digit number.
What is NTOA?
There are three ways to display an IP address. As a binary number, in octet form, and in NTOA form.
Here is the same IP in the three different formats (spaces added to the binary version for clarity)
Binary
- 1011101 00101111 11001000 1000101
Octet
- 46.151.228.69
NTOA
- 781706309
Why do I care?
This may lead to a server that we can connect to. Likely, this will be ftp, telnet, http, or perhaps ssh. It will likely use an easily discoverable password (so please do not bruteforce these systems).
Research Notes
For anyone who wants to research these IPs, the below may help (could use a lot of cleanup, but I am lazy)
Invalid ranges (Do not waste time working on these):
- 0.x.x.x
- 10.x.x.x
- 127.x.x.x
- 169.254.x.x
- 172.16.x.x-172.31.x.x
- 192.168.x.x

Lookup Data
Status
So far, all filenames have been checked, and it does not seem to have gone anywhere. Jippen 19:43, 7 March 2010 (UTC)
Don't you think about the following strange thing? All the ip-s are in the USA or something, except for one, which is in Taiwan. This is like in IQ tests. Maybe the clue is in the whois data for that ip? Zanon 04:59, 30 May 2010 (UTC)
