As my job purpose, it pushs me to have a need to calculate IP with number of host or subnet, and I find these kind of product is chargable, so I think I should write one for myself, and also for other users.

Newton IP Calculator provides the following functions:

- IP address converter (in v1.32)

- Network listing (in v1.3)

- Network tool (in v1.36)

- MAC address and vendor mapping (After v1.1)

- Design network with specify number of subnet or hosts

Newton IP Calculator is written in VB, and therefore it contains a BIG (really big) runtime library.

Update Description:

v1.36:

- Introduce Network tool, first release only contain ping function.
