It is called subnetting. Subnetting is taking an address range (for example a class C address range) and assigning VLSM (variable length subnet masks) to break it up into smaller address ranges.
It is called as VLSM (Variable Length Subnet Mask) which is a type of Classless Inter-domain Routing(CIDR). Most commonly it's referred to as subnetting.

An IPv4 address of 75.76.77.68 is considered a Class A address. A class A address ranges from 1.0.0.0 to 126.0.0.0
This is a class C address. This class ranges from 192.0.0.0 to 223.255.255.255
A public ip address can be anything that is not in these three ranges. 10.0.0.0 - 10.255.255.255, 172.16.0.0 - 172.31.255.255, or 192.168.0.0 - 192.168.255.255.
Consist of the upper-left cell address and the lower-right cell address, separated by a colon
Yes, it is an address in one of the private IP address ranges that have been defined and reserved.The private IP address ranges are set as:10.0.0.0 through 10.255.255.255172.16.0.0 through 172.31.255.255192.168.0.0 through 192.168.255.255Any address in these ranges can be set up and used by homes, offices, and anyone else and the communication will not be routed to the Internet because they are defined as unroutable. They also will not cause any IP address conflicts on the Internet since nothing Internet-accessible exists in those address ranges.If you have any other questions about IP addressing, feel free to drop me a line.
Private IP address ranges:10.0.0.0 to 10.255.255.255172.16.0.0 to 172.31.255.255192.168.0.0 to 192.168.255.255Definitely private =)This is a Class B public address because the first octet ranges from 128 and 191.Sorry! 172.16.50.100 falls in the category of private ip networks.
It is the name box, with will show the address of cells and also names given to cells or ranges.
IP address ranges are generally assigned geographically and so the general location of any one IP address can usually be determined. Certain websites accessibility are location specific and usually controlled by the ISP. BBC iplayer is an example where it cannot be used if a non-UK IP address is detected. Clearly this method of controlling access can be circumvented using VPNs and remote severs and so on but these require additional software and services.
Select the first range as normal. Then press and hold the Ctrl key and select the other range with the mouse. The first range will stay selected. You can select as many ranges as you want using this method.
Reserved IP addresses are 10.0.0.0 to 10.255.255.255 172.16.0.0 to 172.31.255.255 192.168.0.0 to 192.168.255.255 and 169.254.0.0 to 169.254.255.255 Every address in these ranges is considered reserved or private, meaning the internet will NOT route to them without an NAT.
