Subnet Calculator is an online tool that allows you to quickly determine the basic parameters of an IPv4 network by IP address and CIDR prefix. It is enough to specify the address and mask length, after which the service will automatically calculate the network address, broadcast address, subnet mask, wildcard mask, range of available hosts and the total number of IP addresses in the network.
Our tool helps you set up equipment and design local area networks, as it allows you to view available addresses and avoid crossing them. The tool provides calculation results in decimal, binary, and hexadecimal formats, as well as the ability to display a mask with leading zeros, indicating that the mask works by bits.In addition, in addition to displaying the larger networks that your range belongs to (aggregation), the mask calculator also provides you with information about individual, smaller subnets that your range can be divided into. This reduces the likelihood of calculation errors when creating new VLANs or segmenting the infrastructure.
