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.
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.

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!

This is a great tool for networking students as well as the network administrators who are working towards their certifications such as, CCNA, CCDA, CCNP, CCIE etc.
In networks having many unassigned IP addresses, a variable-length subnet mask (VLSM) can provide more efficient use of address space.
★ No additional special permissions required.
★ No Internet connection required.
★ No ads.

This application allows the users to choose if they want to use the subnets "Subnet zero" and "Subnet All-ones" (subnets that were not recommended to use in the past, but most devices allow them now).
You can make up to 128 subnets in this application version (with its information shown on the screen).
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.
