NET 4000 Chapter Notes - Chapter 11.1.6: Private Network, Default Gateway, Broadcast Address
Document Summary
An ipv4 address is a 32-bit binary number represented as four octets (four 8-bit numbers). Ipv4 addresses can be represented in one of two ways: In decimal notation, the value of each octet must be between 0 and 255. In binary notation, each octet is an 8-bit number. To convert from binary to decimal and vice versa, memorize the decimal equivalent to the following binary numbers: To convert from binary, take each bit position with a 1 value and add the decimal values for that bit together. 10010101 is: 128 + 16 + 4 + 1 = 149. The subnet mask is a 32-bit number that is associated with each ipv4 address that identifies the network portion of the address. In binary form, the subnet mask is always a series of 1s followed by a series of 0s (1s and 0s are never mixed in sequence in the mask).
