The number that each field contains should be in the range of 0-255. It contains four octets or fields separated by 'dot,' and each field is 8-bit in size. The above diagram shows the address format of IPv4. The address format of IPv4 is represented into 4-octets (32-bit), which is divided into three different classes, namely class A, class B, and class C. The network address will be the same for each host in a network, but they must vary in host address. With the help of the host address, each machine is identified in your network.
Host Address: A host address is a specific address number assigned to each host machine. In the above figure, the network address takes two bytes of IP address.
Network Address: The network address specifies the unique number which is assigned to your network. The starting address bits decide from which class an address belongs. Each address class defines a different number of bits for its network prefix (network address) and host number (host address). Out of these, classes A, B, and C are most important. These divided IP classes are class A, class B, class C, class D, and class E. Originally IP addresses were divided into five different categories called classes. To know more about the difference between IPv4 and IPv6, look at our article ipv4 vs. IPv6 provides a large address space, and it contains a simple header as compared to IPv4. The IPv4 is a 32-bit address, whereas IPv6 is a 128-bit hexadecimal address. The main difference between IPv4 and IPv6 is the address size of IP addresses. IPv6 is the next generation of IP addresses. IPv4 produces 4 billion addresses, and the developers think that these addresses are enough, but they were wrong. It is a 32-bit address written in four numbers separated by a dot (.), i.e., periods. It is a current version and the most commonly used IP address. Types of IP AddressĪn IP address is categorized into two different types based on the number of IP address it contains. An IP address is represented in an integer number separated by a dot (.), for example, 192.167.12.46.

IP address is a short form of "Internet Protocol Address." It is a unique number provided to every device connected to the internet network, such as Android phone, laptop, Mac, etc. It has an average rating of 4.Next → ← prev IP Address Format and Table The CCNA is by far the most in-demand networking certification by employers, and the Gold Bootcamp is the highest rated Cisco course online. If you want to learn more about networking and get the Cisco CCNA certification, we highly recommend the Cisco CCNA Gold Bootcamp as your CCNA training course. Because of this, only up to the first 999 subnets are displayed.ĭownload our Subnet Cheat Sheet for all the essential information you need to quickly perform subnet calculations in your head. Remember, the IPv6 address space can be huge. This IPv6 subnetting calculator is provided to help you understand the IPv6 address space better and to study for exams – you should always use a /64 subnet mask on real networks. This can lead to a lot of ‘wasted’ addresses, but the IPv6 address space is so large that it isn’t a concern. Note that best practice is to always use a /64 subnet mask for simplicity on real world IPv6 subnets with hosts. This calculator can be used for IPv6 in the same way as our VLSM calculator is used to plan an IPv4 network.
