Special offer, must end soon! ☆
This is a great tool for networking students as well as the network administrators or network IT engineers who are working towards their certifications such as, CCNA, CCDA, CCNP, CCIE etc.
This app has following operating features:
- Generates an IPv4 address along with subnet mask as a Question.
- User can enter their answers for the Network address, Broadcast address, First host and Last host in the respective fields.
- User can check the individual answer by 'Check' button.
- 'Help' returns the correct answer to cross check the answer written.
No internet connection required, no ads.

A single slider acts as a selector for the CIDR, the netmask, and to scale the # of hosts needed in your subnet network.
The application is useful for subnetting in tandem with an Android web browser or just for educational purposes. Education is emphasized by real time updating of network, broadcast, netmask, first and last address of the subnet, and the number of usable IPs in several different formats (dotted-decimal, hexadecimal, octal, decimal, binary and decimal). Also there are basic notes.
There is real time updating of output as you change values and move the slider to change the netmask/mask bit. Touching the output will cycle through several different formats. Long presses will enable menus for copying to the clipboard.
IPv4 functionality is finished. IPv6 will follow in an update.
No ads nor special permissions required! Also, this subnet calculator does not suffer from the "there's no dot on my number keyboard" problem.

An easy to use, simple subnet calculator that takes the hassle out of the many intricacies involved with the ipv4 subnet system. This tool will allow you to accurately subnet different class networks as well as calculate the number of hosts allowed.
The subnet calculator is as flexible as possible, allowing for a multitude of ways to automatically advance to the next field with the intentions of allowing for multiple keyboard layouts. After entering in an octet you can hit any of the keys to advance fields. Also, after three digits entered, the field will advance automatically.
- The period key
- The Space key
- The * key
- The # key
You can quickly and easily retrieve the network range a host device to effectively determine if your device resides within your given network configuration.
The binary tab illustrates some of the patterns that can help the beginner start to learn the subnet process.
Quickly and easily e-mail or save various network configurations for reference later.

As the life of the Internet continues to grow, the exhaustion of IPv4 public addresses is inevitable. IPv6 has been gaining a higher demand in the market place. The slightly different learning curve and complexities with IPv6 addressing can make a daunting task in subnetting and summarizing your network.
The ipv6 Subnet Calculator will simplify the process by allowing you to subnet your IPv6 enterprise properly and accurately. Also, included is an EUI-64 MAC conversion tool to make ease of finding addresses on your network where EUI-64 is implemented.
The ipv6 Subnet Calculator is Android, Ice Cream Sandwich tested and approved!
