IP Address Classes

IP Address classes
Speaking Ip Address, let's talk IP Address Classes his former
IP Address is the identifier that is used to give addresses on each computer in the network alias on the network address of the computer logic.
The IP address is a representation of 32bit binary number that is displayed in decimal form with a split dot.

IP Address consists of a network ID and host ID. Network ID (Net ID) indicates the network number while the host ID identifies a host within a network. Examples of valid IP address is 10.150.0.2 Classfull Addressing A method of sharing an IP Address classes, namely:

Class A
A first bit value is 0
IP Address is between 0 to 127
Using 8-bit network address and 24 bits for host addresses.
Having a network 126 (0 and 127 is reserved) with 16,777,214 hosts for each network.
Allocated to the network with a large number of hosts.

Class B
The value of the first two bits are 10 IP Address
Ip between 128 to 191.
Using 16-bit network address and 16 bits for host addresses.
Having a network with 65 532 16 384 hosts for each network.
Allocated to large and medium networks.

Class C
The value of the first three bits of the IP address is 110
Ip between 192 to 223.
Using 24-bit network address and 8 bits for host addresses
2097152 has a network and 8 bits for host addresses.
Allocated to network with less than 254 hosts

Class D
The value of the first four bits of the IP Address is 1110
IP multicasting is used for the purposes of Class E
The value of the first four bits of the IP address is 1111

Class E
reserved for experimental purposes (research) Classless Addressing these methods are being applied, namely the allocation of IP addresses in the notation Classless Inter Domain Routing (CIDR).

In impleentasinya, not apart from the term network prefix. Network Prefix is another term to describe the IP addresses that pointed to a more specific network. Writing a class IP network prefix address using a slash (slash) "/" followed by numbers that indicate the network prefix length in bits. For example, when writing class A network with IP allocation 10.xxx.xxx.xxx, its network prefix is written as 10 / 8. Figures / 8 CIDR notation indicates that a number of bits used by the network prefix, which means it netmask 255.0.0.0 with a maximum of 16,777,214 hosts on a network node.

that's how IP Address Classes.
