Nokia6310 Subnet Calculator 2.0

the author of this app says:

This is a Java midlet subnet calculator for a Nokia6310 mobile phone (its a generic midlet so it could work for other java enabled phones - but not tested). Input an IP address and subnet mask, mask bits and number of hosts wanted and it will display the hosts, network address, broadcast address, first IP address, last IP address and inverse subnet mask. It has menus for alternative input of details using the navigation keys.
