At one point during Stanley's attempt to hack into the Department of Defense database, his screen shows six numbers that appear to be IP addresses. (The first is 213.225.312.5.) The numbers between decimal points in an IP address, called "octets", are decimal representations of 8-bit numbers (8 binary digits of either 0 or 1). Therefore, the range of decimal numbers for an octet is 0 to 255, because 11111111 in binary is 255 in decimal. The IP addresses on Stanley's screen each contain one octet higher than 255 (such as 312 in the first example), which is apparently the filmmakers' way of ensuring that no one's real IP address appeared.
