A powerful IP Subnet and FLSM calculator for network administrators.
This is a great tool for networking students as well as the network administrators or network engineers who are working towards their certifications such as, CCNA, CCDA, CCNP, CCIE etc.
Solves any question by Subnet mask, Subnet mask bits, Bits per subnet, Hosts per subnet, Number of subnets. This app contains examples and shows network ranges and more information about.
No internet connection required, no ads.
tags: IT engineers, wildcard, ipv4.
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.

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.
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.
I will be very appreciated if you can spend your valuable time to give this app a good rate.

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!

for IP networks. It calculates the possible number of subnets and hosts,
and various other useful data. Class Inter-Domain Routing (CIDR) is also
supported. A Base Converter converts between decimal, binary, octal and
Results of the CIDR calculation provide the wildcard mask, for use with ACL (Access Control Lists), CIDR network address (CIDR route), network address in CIDR notation and the CIDR address range for the resulting CIDR network.
Do your sub-netting without typing in any ip addresses, easily slide to what you want, then sent it to yourself as a CSV file. Change from left handed to right handed so your thumb does not obscure the information you need to see when you are sliding.
No more messing around createing spreadsheet for all your point to point networks, Subnet Master take the hard work out.
This is also a great tool for Networking students to learn sub-netting. Use it to check your work while you are working for your Network+ or CCNA
