I ran out of credit on my prepay cellphone as I use it to connect to the internet by tethering it to my PC. I was changing the last oclet of the IP which was associated with the "...sorry, your have insufficient funds to continue browsing, please topup." located at http://pdaportal.telecom.co.nz/mobile/static/outoffunds.html (210.55.11.94).

I came up with:

1. https://210.55.11.52/index.aspx?PageID=Login
2. https://210.55.11.54/Authentication/Login.aspx?ReturnUrl=/index.aspx
3. https://210.55.11.57/index.aspx?PageID=Login/
 
Does anyone know what these would be used for?
