An IP address or Internet Protocol address is a numerical identification and logical address assigned to devices that are used to connect to a network or to an internet with IP translation. For example, the IP address 192.168.1.1 is a default IP address that is used by many devices like those modems in which broadband companies use like LinkSys home broadband routers. The word IP address are commonly used terms because of the rampant use of the internet but many still do not know what it means. RFC 1918 has distinct 3 private address ranges: 10.0.0.0 10.255.255.255, 172.16.0.0 172.31.255.255 and 192.168.0.0 192.168.255.255. A distinctive quality of Private IP addresses is that they can be used on many unrelated networks. In this way private IP addresses are said to be non routable or transferrable. In other words, you are unable to use this IP address to connect to the internet without the use of Network Address Translation or NAT. If you and I can both have a component on different networks with the IP address 192.168.1.1, we will not be able to connect these two different networks because of the address conflict will result. However, the disadvantage of this is that with any IP addresses, only one component on a network can utilize this that is why it is unique in order to avoid conflict. Thus it is important to certify whenever you connect a new component to an available network that the default IP address of the new component which will be in the RFC 1918 range of private IP addresses with IP translation, is not also used by one of the other mechanism on the network.
