PalmVIIx

I need an App that can turn my Palm into a "Handheld" Subnet Calculator plus convert IPv4 Binary, Hex & Decimal to each other. This is Computer Networking specific.

Here is an example of a Subnet Calculator:

Basically, you input the Class of the Network, its IP Address and the # of bits you want to borrow and then the Calculator spits out how many Subnets you will get, # of Hosts per Subnet, Host Range, Mask bits, etc.

Here is an example of a IPv4 Binary, Hex, Decimal Converter:
http://www.kloth.net/services/iplocate.php

Basically if you input any IPv4 Address either in Binary, Hexadecimal or Dotted Decimal it will spit out its converted answer in the same formats.

I would appreciate if you could at least point me to a Scientific Calculator App that can do Exponents, Binary and Hex.

Thanks
