Subnet Calculators

  • IPv6 Subnet Calculator

    IPv6 Subnet Calculator for mapping your own hierarchical subnets

  • IPv4 to IPv6 converter

    This calculator slash converter can assist in the conversion of IPv4 type IP numbers to IPv6 notation, supporting IPv6 condensed and alternative format.

  • IPv4 CIDR Calculator

    A very complete CIDR Subnet calculator with Hex conversion and easy network range and subnet mask adjustement.

  • IP Subnet Calculator

    IP Subnet Calculator: with an IP address and subnetmask you can calculate the number of hosts, start IP and end IP of your range, network and broadcast address and bits user for networks and hosts.

  • HEX Subnet Calculator

    input the IP address and adust your mask as desired and click on the Calculate button. This will then calculate the first and last address for the subnet as well as the Multicast addresses together with hexadecimal notations.

  • IPv4 Wildcard Calculator

    This subnet calculator takes an IP address and netmask and calculates the resulting broadcast, network, Cisco wildcard mask, and host range. By giving a second netmask, you can design subnets and supernets. It is also intended to be a teaching tool and presents the subnetting results as easy-to-understand binary values.

  • IPv4 Address Calculator

    Simple and fast subnet calculator to determine host start address, network address, broadcast address and CIDR notation for the subnet mask, including number of host in your subnet.

  • Address Range calculator

    Very fast and simple subnet range calculator. With an IP address and subnet mask you can quickly view start and end address.

  • DEC to HEX calculator

    Use this calculator when you know your IP number and Subnet Mask and want to find out the correct Router Address, Network Address, and Subnet Broadcast Address with additional hexadecimal notations.

  • SubnetMask Calculator

    With a start and end address this calculator will determine the smallest available subnet with the corresponding subnet mask.

  • Local or Remote route

    This very simple binary subnet calculator which illustrates the binary calculation of a subnet and the mechnisme used to determine of a IP adress and subnet mask
