Reviews of aSubnet

  • Invaluable

    I use this for double-checking my wildcard masks for access lists & making sure I didn't fat finger or flub any subnetting. Super handy for VLSM.
  • A great simple tool!

    I find myself using this a lot for unusual CIDR situations. Any chance we'll see IPv6 support?
  • It's back! Thank you!

    Like many I used to use this tool every day but have been disappointed as it didn't work with IOS 8.3. This latest update fixes the slider bug and gives it a RetinaHD overhaul. All I can say is bless you app developers. Great job. I have my go to tool back.
