how many bits are used for the source ip address
An IP address consists of 32 bits. Instead of expressing IPv4 addresses 32 bits at a time using binary notation (Base 2), it is standard practice to segment the 32 bits of an IPv4 address into four 8-bit fields called octets. Each octet is converted to a decimal number (base 10) from 0â255 and separated by a period (a dot).
