There's a technique we used to use but I don't know if it works any more - I tried it on Google today and it said my submission was successfully received - so maybe - perhaps someone can confirm if it does still work?
Anyway here is what you do.(You *MUST* have a unique IP for your domain to use this technique)...
1 Get your IP - In my case
http://sex-bb.com is 66.230.231.71
2. Multiply the first number by 256*256*256 (Here the result would be: 1107296256)
3. Multiply the second by 256*256 (we would get: 15073280)
4. Multiply the third by 256 (returning: 59136)
5. Add all these three numbers together then add the fourth part of the IP (this would result in: 1122428743)
Now all you have to do is put
http:// in front of the name and you have another URL, like this...
http://1122428743
Anyway, as I said, I'd be curious to know if this still results in getting you extra listings...
