What is 10.0 0.0 8 mean?
A network numbered “10.0. 0.0/8” (which is one of those reserved for private use) is a network with eight bits of network prefix, denoted by “/8” after the oblique. The “8” denotes that there are 24 bits left over in the network to contain IPv4 host addresses: 16,777,216 addresses to be exact.
What does 168 mean in an IP address?
The subnet mask defines what portion of the four “octets” (separated by dots) of an IP are used as network identifiers and what the actual unique computer node identifier is. Example: 192.168. 1.1 with a mask of 255.255. 0.0 means that the 192 & 168 represents the network and the 1.1 is the unique identifier.

What is a Class C private IP address?
Most LAN networks use the “Class C” private IP address range. So in a typical network in a home or business the local IP addresses will start with 192.168. In a Class C network the first three groups of the IPV4 address must match exactly for the devices to be able to communicate.
What are the valid public IP address ranges?
Public IP addresses will be issued by an Internet Service Provider and will have number ranges from 1 to 191 in the first octet, with the exception of the private address ranges that start at 10.0.0 for Class A private networks and 172.16.0 for the Class B private addresses.
