IP Version 4 Numbers, Address Classes and Formats
===============================================
Three Key IP addresses define a network , the network address, the broadcast address, and the sub-net mask. The network address is always the first IP address in range, The broadcast is always the last address in the same range . The sub-net mask helps your computer define the difference between the two addresses. You can assign IP addresses between the network and broadcast addresses to any computer on the network .
A sub-net mask is also known as a network mask or net-mask. An example of an IPv4 net-mask is 255.255.255.0, which is class c net-mask it can also be defined by the numbers of associated bits ,24.
192.168.122.0 / 24.
Related to networking and net-masks is the concept of the gateway. It's an IP address that defines the junction between the local network and an external network. While that gateway IP address is a part of the local network such as the public Internet. The gateway IP address is normally configured in the routing table for the local system, as defined by the route or netstat -r command.
================================================
TCP/IP is a series of protocols organized in Layers, known as a protocol suite. It was developed for Unix and eventually as the standards for communication on the internet. With the IP Address you can organize a Network .
Every computer that communicates on a network needs its own IP Address . Some address are assigned permanently to a particular computer, these are known as static addresses.Others are leased from a DHCP server for a limited amount of time,these are also known as dynamic IP addresses.
IPv4 are organised into five different classes :
CLASSES RANGE NOTE
A 1.1.1.1 - 126.255.255.254 Network allowed up-to 16 million computers
B 128.0.0.1 - 192.255.255.254 Network allowed up-to 65000 computers
C 192.0.0.1 - 223.255.255.254 Network allowed up-to 254 computers
D 224.0.0.1 - 239.255.255.254 Reserved for multicast
E 240.0.0.1 - 255.255.255.254 Reserved for experimental use
Private Range of Classes
A 10.0.0.0 - 10.255.255.255
B 172.16.0.0 - 172.31.255.255
C 192.168.0.0 - 192.168.255.255
Address Formats :
Unicast :
A Uni-cast address is associated with a single network adapter. Route-able uni-cast address include a 48-bit network prefix, 16-bit sub-net identifier, and a 64 bit interface identifier associated with a network adapter hardware address.
Multicast :
A Multicast address is used to send a message to multiple network adapters simultaneously. The organisation of a multicast address varies .
Anycast :
An Any-cast address is used to send a message to one of several optional network adapters. It's useful for systems with multiple backups, such as a group of web servers. Any-cast have the same basic organisation as a uni-cast address .
