Basics of communication with IP

1.3.2.1

IPv4 address

Range of values for IP address
The IP address consists of four decimal numbers with the range from 0 to 255, each number
separated by a period; example: 141.80.0.16
Range of values for subnet mask
The subnet mask consists of four decimal numbers with the range from 0 to 255, each
number separated by a period; example: 255.255.0.0
The binary representation of the 4 subnet mask decimal numbers must contain a series of
consecutive 1s from the left and a series of consecutive 0s from the right.
The "1" values specify the network number within the IP address. The 0s specify the host
address within the IP address.
