aSubnet

I like it - just what I was looking for and needed, and am way too lazy to calculate. However, the slider seems to get stuck often, and in fact, not accept input for seconds at a time (tried on 2 phones) unless you 'let it be' for a bit.Otherwise, it's nice, and free.

This used to be my goto subnet calculator. I gave them a chance to fix it after the iOS update broke it. Too late now. Bye.

You type in the IP address and theres a slider bar to adjust your network bits. Everything is calculated. The info button lets you change to hex. A nice addition would be a filed to put in hex to convert that. Still waiting for a telnet app....

There is some eyecandy that could be added but for me, a total geek, I love this app! I gives my ip so I know who is all on my network (my router gives a list of ips)! Über Kudos to the developer! You guys forget that if you post stuff that does not help us devs we cannot improve our apps! I know this by being a fellow developer! This is not easy to make! If you think it is, get a mac and download the iPhone SDK and try! We all want more apps! Even if you cannot do this, maybe you had another idea! Just help yourself by helping us developers making better apps with feedback that helps! BTW: I think that the BG should be brighter, as the iPhone/iPod touch is dark enough!

Useful tool for network administrators and others who have a need for calculating CIDR and network address blocks.

Simple. Perfect! Well done.

As a network engineer this app is great.

Well designed and executed. Works well within the iPhone interface. Extremely valuable to network engineers/techs.
