In the prior art the notion of a magic pen is recognized. This pen when used in a table of input fields, may be used to swipe an area and have the area be filled with specially formatted data the pen is capable of entering into each field. These are somewhat analogous to fill function found in spreadsheets, but they are context sensitive based on the type of field. The magic pen application described here is a fill technique for TCP/IP addresses. The magic pen allows the user to select a set of input fields, and fill these fields with valid TCP/IP addresses. The pen process not only fills the fields with valid address ranges, but the process queries the DHCP server to determine a range of addresses that are free and may be used. Figure 1 demonstrates the process. Presented is an input table that shows users, other user information, and input fields to specify a TCP/IP address for each user. The range of cells for the addresses is marked. Then the IP magic pen is selected from the toolbar and clicked on the marked range. The underlying process queries the DHCP server for a list of free addresses that matches the number of cells in the range. Each range is filled with a valid address.
