Dotless IP Address

This is a concept I had forgotten about until recently, it can often serve as a simple means of code obfuscation and is also sometimes referred to as “Decimal Address”.

Some background:

• DNS is used to convert a URL/domain name into an IP address that is used to contact the remote machine.
  EXAMPLES:
  localhost = 127.0.0.7
  giantgeek.com = 99.138.127.198
• IP addresses (as IPv4) are represented as groups of 4 hexadecimal or decimal octets.
• Those numbers can be plugged into a simple formula to be represented as a single large integer.

As such, you can use the following as equivalents:

• http://localhost
• http://127.0.0.1
• http://2130706433
