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 a router 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.
No ads nor special permissions required! Also, this subnet calculator does not suffer from the common "there's no dot on my number keyboard" problem.

I will be very appreciated if you can spend your valuable time to give this app a good rate.
✔ Classless Inter-Domain Routing (CIDR)

Support CIDR or Subnet input for calculation.
Easy to navigate between field :
- Auto move to the next field if there is 3 digits input at the IP and Subnet input fields
- Auto move with pressing of dot, star, or hash
Running on Android 2.1 and up.

Four in one subnet calculator - CIDR, Classful, Supernet (route summarizer), IPv6.
Fast subnet mask selection with slider.
Easy navigation among calculators.
Automatic result updates on input change.
Simple and intuitive
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.
Please feel free to contact me with any features/updates you would like to see added to this tool.
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!
Please feel free to contact me with and features/updates you would like to see available.
This subnetting calculator is highly configurable, simply input an IP address, and any other field then hit calculate to fill out the information. Supports both CIDR, and Classless subnetting.
The LITE version of the subnetting calculator contains advertisements, and will receive no more extended functionality beyond bug-fixes.
Please submit any feature requests, or bug reports :)
Varying one parameter mentioned above, the results allow checking all the rest also provide data on: the first octet range, wildcard ACL (Access Control List), range of IP addresses available for hosts, ID subnet, broadcast address, map of the bits.
The calculations follow the applicable rules issued by the IETF ,international level, and can be used for projects of LANs, configuration and verification of data also in a home network, SOHO (Small Office Home Office) or enterprise.
On the main screen use the spinners to select the codec, bitrate, payload size and any VPN overhead and the app will calculate the amount of bandwidth needed for a voice over IP call. Fill in the number of expected users and it will also calculate the total bandwidth required using the given settings.
There are checkboxes for enable cRTP (+Checksum) and to add an additional 5% overhead.
Sliding the small arrow at the bottom up will reveal more info on the settings used in the calculations.
Flick the screen from right to left and the app will calculate the number of calls available on certain popular circuit rates with the given settings.
On this screen you can also enter a custom circuit rate by entering you chosen value in the text field and hitting the "ReCalc" button. The list will be recalculated with you custom circuit at the top.
Finally the Converged checkbox will only allow calls to use 33% of a given circuit speed for when you are interested in how much a circuit can provide in a converged network.
