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.
This is ad-supported app, to support the development process.
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.

IPv4 subnets are used in order to expand the capacity of hosts and efficiently use one assigned IP.
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 Internet connection required.
★ No ads.

Non-GeoIP self-develop ASN information database - "ONLINE database update available on Version 7.0". Our back-end system continues to analysis the real live network changed for the internet.
You may understand how your mobile network operator/ISP connected to the destination domain and the potential bottleneck network transit by route tracing with network transit/peering company ASN information result.
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.
Following is a sample network calculator.
When you set the address of the writer, will be required for this application.
Are you using a network converter, the following information is available also.
- Subnet Mask
- Number of hosts
- Wildcard Mask
- Start IP
- End IP

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.
