This calculator returns a variety of information regarding Internet Protocol version 4 IPv4 and IPv6 subnets including possible network addresses, usable host ranges, subnet mask, and IP class, among others. Related Bandwidth Calculator Binary Calculator. A subnet is a division of an IP network internet protocol suite , where an IP network is a set of communications protocols used on the Internet and other similar networks. The act of dividing a network into at least two separate networks is called subnetting, and routers are devices that allow traffic exchange between subnetworks, serving as a physical boundary. IPv4 is the most common network addressing architecture used, though the use of IPv6 has been growing since An IP address is comprised of a network number routing prefix and a rest field host identifier. A rest field is an identifier that is specific to a given host or network interface. CIDR is a method used to create unique identifiers for networks, as well as individual devices. For IPv4, networks can also be characterized using a subnet mask, which is sometimes expressed in dot-decimal notation, as shown in the "Subnet" field in the calculator. All hosts on a subnetwork have the same network prefix, unlike the host identifier, which is a unique local identification.

Our Platform. Subnetting with the help of a network subnet calculator allows you to compartmentalize and organize your network in a logical manner.

The IP Subnet Calculator performs subnet calculations for the given network address block, subnet mask, maximum required hosts per subnet and determines the resulting broadcast address, subnet, Cisco wildcard mask and host range. Eliminate network downtime and critical network issues. With instant AI alerts, reduce resolution time by identifying and fixing issues in advance. There comes a time when the network becomes too large to manage and performance numbers hit an all-time low as a result of too much traffic. The practice of dividing the network is called subnetting, and a tool that can identify these different divisions is called a subnetting calculator. Every subnet has an address to represent it and these subnets are interconnected via router.

The router needs network address and subnet mask to find out whether the incoming IP packet has to be routed to any of its subnetwork.

This IP subnet calculator makes subnetting easy, providing full subnet information like IP ranges, subnet masks and more from just basic network information. The IP subnet calculator provides a quick and easy way to find information about subnets for IPv4 and IPv6, including details like network addresses, host ranges, and subnet masks. Using the calculator is simple. For IPv6 networks, select the network prefix length and enter the IP address before hitting calculate. For either network type, just those few basic details will provide relevant information about the actual or possible subnet. Although it is possible to calculate it manually, it is not easy. The process requires converting IP addresses into binary, adding the subnet mask, and then converting them back into decimal or hexadecimal. Using a subnet calculator eliminates the risk of errors that come with manual calculations, which may result in overlapping subnets and difficulty in identifying networking problems later. And while most people who use a subnet mask calculator will be IT professionals who understand networking, our version only requires basic information.

An example IPv6 address is ready to use. A subnetting calculator like this one can work with both IPv4 and IPv6. That means the most important 64 bits represent the network identifier, while the less important 64 bits are representative of the host identifier. That gives a result of Let's go through each one to briefly explain how to manually calculate them, linking to further resources for further information. IPv4-mapped IPv6 addresses consist of the prefix ::ffff: followed by the IPv4 address, either displayed in hexadecimal IPv6 native format or the IPv4 quad-dotted decimal format. If you experience a problem with this site that you would like to report, please contact us at ncc iptp. You can reduce the list of subnet masks to choose from by setting the network class option. An IP Subnet Calculator is a tool that may be used to compute the number of subnets in a bigger network, the number of hosts that can fit in a subnet, and the size of all the subnets. Wildcard mask The wildcard mask is the subnet mask with the bits inverted, therefore selecting the host part of the IP address.

This online IPv4 Calculator can be used to calculate subnet information based on an IP address and a subnet mask. You can fill in an IP address and choose a subnet mask by using the pulldown on the subnet mask field, or if you prefer the pulldown on the mask bit. When you know how many hosts you need within a subnet, you can also choose to enter this number at "hosts per subnet".

Need for a IPv4 subnet calculator Every subnet has an address to represent it and these subnets are interconnected via router. When it comes to notation, the CIDR number will usually follow the IP address and will be separated from it by a slash. For the first usable host address, we add one to the network address. Microsoft Exchange server monitoring. IP type — public or private? The results for our example IP address is: ::ffff:c0aa ::ffff Related Resources blog-icon-res Blog. Set IP Address and Subnet allocation, subnets are calculated after changing focus or pressing enter key. For example, the 6to4 prefix for the IPv4 address You can calculate it by taking the network address the 1st address within the subnet , adding the number of addresses in the subnet, and then subtracting one. One subnet mask limits how many IP addresses can exist on a single network, but multiple subnet masks can be used to organize an entire network into sub-subnets. Sign Up Demo Learn more. It was introduced to solve the problems of rapidly growing routing tables and IPv4 address pool exhaustion.
