As reported by Kaspersky, most browsers (and proxies ?) supports URL with IP addresses in format others than decimal, which can be a good way to bypass network security:

  • http://0×42.0×66.0×0d.0×63/
  • http://0×42660d63/
  • http://1113984355/
  • http://00000102.00000146.00000015.00000143/

    The previous URL are working with both Firefox and Chrome.
