Version 1.2
A Free IPv4 Calculator For The Ease Of Subnetting
ipCalc is a simple and useful app for calulating the range of the host part of a subnet mask within an IPv4 network very quickly.
  • Easy to use
  • Fast overview of your client ranges
  • Shows iPhone IP Addresses (internal & external)
  • Built for IOS 7
  • Completely Free! / Ad supported

Compatible with iPhone and iPod touch. Requires iPhone OS 7.0 or later. WiFi, Edge, or 3G network connection not required.


You can (optionally) enter your client IP. Jumping between the fields of the 4 octetts can be done using the decimal seperator key for quick input. Then use the slider to set the subnet bits of your mask. The app shows you then details of your network, like client count, client range, network address, broadcast address and wildcard mask. There's also an information screen that shows you your IP addresses (LAN and Internet).
A useful tool for every network engineer.

ipCalc is 100% free to use. You may use it for free or commercial projects.
