192.168.1.254 is a private IP address, that is used by a large number of router manufacturers in devices such as ADSL and cable modems. IP addresses are organized into classes and 192.168.1.254 is a class C address. IP networking protocol comprehends addresses as 32-bit numbers. To figure out which IP address belongs to which class, we need to know what each class comprises of.
The addresses are organized into classes, the most common are Class A, Class B and Class C
This class comprises of networks from 22.214.171.124 to 127.0.0.0. It provides for a 24-bit host part, and allows 1.6 million hosts per network. These are designated to networks which have a large number of total hosts. The values start from 1 and end at 127.
Class B contains networks 126.96.36.199 to 188.8.131.52. The network number is in the first two octets. This class allows for 16,320 nets allowing roughly 65,024 hosts each. These are designated for large to medium networks. The values start from 128 and end at 191.
Class C networks range from 192.0.0.0 to 184.108.40.206, with the network number contained in the first three octets. This class allows for almost 2 million networks and nearly 254 hosts. These networks are generally used in LANs (Local Area Network). These numbers start from 192 and end at 223.
These are the main addresses, the other two are Class D and Class E. These classes are not intended to be allocated to hosts, they are used for other specific purposes. Class D addresses are used for purposes such as multi-casting and experimenting, while Class E addresses are basically reserved for the future.
First octet in binary – 110XXXXX
The range of the first octet is 192 – 223
Network ID – a.b.c
Class C network IP address range = 192.168.0.0 – 192.168.0.255
Class C network IP address range = 192.168.1.0 – 192.168.1.255
Class C network IP address range = 192.168.2.0 – 192.168.2.255 … etc
For all the Class C networks
Subnet mask = 255.255.255.0
Network address = 24 bit
Computer address = 8 bit
Now that we know how IP addresses are segregated, let us take a look at the IP address “192.168.1.254 ”. It is a private IP address, since it fits into the IP range which is reserved from IANA (Internet Assigned Numbers Authority) as a private range. There are only so many “real” IP addresses available today. They are all very near to being completely used up, and hence are difficult to obtain.
192.168.1.254 is an IP address, that is reserved for private networks that are not part of the Internet. Many home networks may be connected to the Internet, but they are not a part of it. This is where the network router comes into action; it guides the network data to the suitable computer on the home network. This brings up the need for many computers to share the same ISP connection, as they are not directly reachable from the Internet. It does have an advantage though, with the rise in virus and other malware ready to infiltrate your computer, it is good if there is no direct contact.
