IP Addressing
An IP address is a unique logical identifier for the node or host connection with the IP network. IP address is actually a Thirty two bit binary number, and showed simply by 4 decimal values of 8 bits each. The decimal values consist of Zero to 255. This is called "dotted decimal" notation.
Example: 192.189.210.078 It is sometimes useful to see the values in their binary form.
Dotted decimal description: 192 .189 .210 .078
Binary representation: 11000000.10111101.11010010.1001110
Each IP address consists of network identifier and node identifier. The IP network is split depending on Class of network. The type of network depends on the main bits of the IP address as displayed down below.
Address Classes You can find 5 various address types. You possibly can select which class any IP address is in by evaluating the very first 4 bits of the IP address.
Class A addresses start with 0xxx, or 1 to 126 decimal.
Class B addresses begin with 10xx, or 128 to 191 decimal.
Type C addresses start with 110x, or 192 to 223 decimal.
Class D addresses begin with 1110, or 224 to 239 decimal.
Type E addresses begin with 1111, or 240 to 254 decimal.
Addresses starting with 01111111, or 127 decimal, are available to loopback as well as for internal testing on a local machine. Class D addresses are reserved for multicasting. Type E addresses are reserved for future use. They should not be used for host addresses.
Now you can discover how the Class determines, automatically, which area of the IP address is among the network (N) and which usually part belongs to the Host/node (H).
Type A: NNNNNNNN.HHHHHHHH.HHHHHHHH.HHHHHHHH
Class B: NNNNNNNN.NNNNNNNN.HHHHHHHH.HHHHHHHH
Type C: NNNNNNNN.NNNNNNNN.NNNNNNNN.HHHHHHHH
Within the example, 192.189.210.078 is a Type C address so by default the Network portion of the address (often known as the Network Address) is determined with the very first three octets (192.189.210.XXX) and the node part is determined with the last one octets (XXX.XXX.XXX.078).
For you to establish the network address for a given IP address, the node section is set to all "0"s. In our example, 192.189.210.0 identifies the network address for 192.189.210.078. Once the node section is determined to all "1"s, it describes a sent out that is brought to all hosts on the network. 192.189.210.255 identifies the broadcast address.
Private Subnets
There are actually 3 IP network addresses reserved for non-public networks. The addresses are 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16. They can be used by anyone setting up internal IP networks, such as an intranet. Internet routers never ever send the private addresses within the public Internet.
