IPv6 addresses have a 128-bit address space that’s represented as eight groups ofhexadecimaldigits. Each group is separated by a colon, and the letters A-F represent the numbers 10-15 to keep the addresses more compact. IP Address Examples 192.168.1.1is an example of an IPv4 address. 200...
We’ll discuss the output in more detail later, but for now, concentrate on the second line, which reports that the host is configured to have an IPv4 address (inet addr) of 10.23.2.4. On the same line, a Mask is reported as being 255.255.255.0. This is a subnet mask, which defines...
the utility nm-online will tell you whether the network is up or down. If the network is up, the command returns zero as its exit code; it’s nonzero otherwise. (For more on how to use an exit code
Every computer has a unique IP address What’s IPv4? The most common type of IP address is IP Version 4 (IPv4). An IPv4 address consists of 4 numbers separated by dots: 192.23.57.125 Each of those 4 numbers is represented by 8 binary digits (also known as an octet). Binary is a la...
An IP address (Internet Protocol address) is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication. In Linux, the IP address is used to identify anetwork interfaceon a computer and to route network packets to their des...
Look at the same IPv4 address in binary: 11011000.00011011.00111101.10001001. Each sequence of numbers in an IPv4 address is called an octet, because each has eight positions when viewed in binary form. If you add all the positions together, you get 32, because IPv4 addresses are considered 32...

Explain IPv4 Versus IPv6. How many bit strings have an equal number of 0's and 1's? What is the IP address of the 61st useable host on the sixth useable subnetwork when subnetting the 172.16.0.0 network by borrowing 6 bits? Provide your answer as a 32 bit binary number, with no sp...
IPv4 (Internet Protocol version 4): This is the more commonly used format and consists of a 32-bit numerical address separated by periods. For example, 192.168.0.1. IPv6 (Internet Protocol version 6): With the growing number of devices connected to the internet, IPv6 was introduced to accom...
