SubnetCalc

admin



May 02, 2014 What makes Pinkie’s SubnetCalc unique is its level of details and the amount of information you get back as well as the flexibility to customize the way information is displayed to you. First and foremost, Pinkie’s SubnetCalc is the first subnet calculator to capture both IPv4 & IPv6 details and present it to you on a well designed screen. IP Subnet Calculator. This interface is designed to take as input settings people find in the control panels on their computers, or via terminal commands like ipconfig on Windows and ifconfig on Linux, Unix & Mac OS X. Ipcalc 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.

💡 Description

SubNetCalc is an IPv4/IPv6 subnet address calculator. Forgiven IPv4 or IPv6 address and netmask or prefix length, itcalculates network address, broadcast address, maximumnumber of hosts and host address range. Also, it prints theaddresses in binary format for better understandability.Furthermore, it prints useful information on specificaddress types (e.g. type, scope, interface ID, etc.).

😀 Examples

  • My host has IP 132.252.150.254 and netmask 255.255.255.240. What are the details of its network?

  • Consider host www.six.heise.de uses a 64-bit prefix length. What are the details of its network?

  • My new host should use Interface ID 0x100 and Subnet ID 0x1234. Generate a Unique Local IPv6 prefix (40-bit Global ID) for my intranet, using high-quality random numbers!

  • Which are DNS reverse lookup name and geo location country of IP 2401:3800:c001::68?

  • Which are the MAC address and Solicited Node Multicast address of 2001:638:501:4ef8:223:aeff:fea4:8ca9/64?
