I have to check for the valid IP Address that is being entered by the user before the IP Address is used for querying the database.
Here are the rules:
if someone enters leading zeroes, for example 192.051 or 192.051.088 the leading zero would be stripped ip address used will be 192.51 or 192.51.88
IP Address should have periods at right places
are all valid entries where as
1922788128 are invalid.
Please let me know which method I should use then I will be able to do it.

What have you done so far? You may find
to be helpful in parsing out each number that is separated by a period. Also,
has methods for converting a
to an int (assuming that the IP address is input as a String).
