Beginner's Guide to IP Addresses

IP adresses tutorial courses material intented to beginners students.

IP address has a network portion and a host portion. In terms of the IP v4 addresses have a network part of 8, 16 or 24 bits according to the address class. Regarding the IP v6 addresses have a network part of 64 bits.

These default masks do not always stick to the particular needs of everyone. Therefore, it is possible to subdivide the networks by default using a subnet mask.

A subnet mask is a number of the same size as the address. The first bits are 1 and designate the network portion. The last bits are 0 and designate the host Party.

Examples: ... 111 111 000 000 111 111 000 000 ...
