10 DIGIT DECIMAL NUMBERS AS IP ADDRESSES

Ever seen one of these used as a web address?

Ever wondered why some people use addresses like this?

Anonymity is the main reason.

Enter the 10 digit pseudo IP Address:
- IP address 0.0.0.0
- Host Name 0.0.0.0

If the Host Name appears as an IP Address, then the Host Name could not be resolved. In which
case, the ARIN system will tell you which organization has been assigned this block of IP addresses.

The Long-hand Method -
One of the longer ways of deciphering these weird "IP Addresses" is to use the calculator provided with Windows - (Start, Programs, Accessories, Calculator). Selecting the 'View' option reveals two choices - select 'Scientific'.

  • Select 'Dec' and enter the number. (3629922059)
  • Select 'Hex' and write down the resulting hexadecimal number. (D85C370B)
  • Split the hex number into pairs of digits (should be 4 pairs). (D8) (5C) (37) (0B)
  • With the calculator still on 'Hex', enter the first (left-hand) pair of numbers. (D8)
  • Select 'Dec' and write down the resulting decimal number followed by a dot. (216.)
  • Switch back to 'Hex' and enter the second pair of numbers. (5C)
  • Select 'Dec' and write down the resulting decimal number followed by a dot. (92.)
  • Switch back to 'Hex' and enter the third pair of numbers. (37)
  • Select 'Dec' and write down the resulting decimal number followed by a dot. (55.)
  • Switch back to 'Hex' and enter the fourth pair of numbers. (0B)
  • Select 'Dec' and write down the resulting decimal number but NO dot. (11)
  • String all your newly acquired numbers together to get the true IP Address 216.92.55.11
