I see that Oracle are changing the names of their x86 Servers. Worth having a note of the URL.
Following on from my earlier post, I have split the Netmask Calculator into two versions; the existing version now has small, subtle adverts at the bottom of the screen. It's a shame the Android apps can't add a simple "Add Google Ads" level of permission to apps; in order to serve adverts, the existing app now needs to request "Full Internet Access".
To preserve the comfort level of installing only apps with absolutely necessary permissions, I have added a "Pro" version, suitably entitled Netmask Calculator Pro. This is priced at £0.99, €0.80 and USD$0.99.
Some apps genuinely need internet access to perform their duties - a web browser or ssh client, for example. Most (including this one) do not, and whilst I do trust virtually all Android apps to behave honourably (and both versions of the Netmask Calculator are of course completely trustworthy), the only way to address Google's broad "internet access" permissions model with the developer's incentive to create applications, is to provide two different versions of the app - one ad-supported but requiring internet access, and the other which requires no permissions at all, in exchange for the price of less than half a pint of beer.
Instead of the "+" symbol that PS4 normally puts before each command, you can get a timestamp.

It's just over a year since I first published my Android Netmask Calculator, and I've published a few more updates to it.
There are some tweaks to make it look slightly better on tablet devices, and it also now shows Binary and Hexadecimal values as well as the Decimal that it showed before.
These are easily toggled by pressing the appropriate "radio" button.
The Binary display doesn't look too great on a phone; by its nature, it has to wrap around. I've yet to get a screenshot on a tablet. Better still, is a video of the tablet display, as you can tilt the device to change the screenshot, which in Binary mode gives a really good visual lesson in how the netmask, network address and broadcast address affect each other.
