hi
input domain testing is divided into 2 categories.
1)boundary value analysis
2)equivalence class partitioning.
boundary value analysis checks the boundaries of the inputs.
*equivalence class partitioning checks the type of inputs we are entering.*

ex:- specifications:- suppose let us take a login page for an application like yahoomail which consists of username and password.
the allowable entites for username is 1)a to z,Ato Z
2)0 to 9,
3) (underscore _)
4)with no special characters and space.
the allowable entites for password is 1)a to z,Ato Z
2)0 to 9,
3) (underscore _)
4)special characters allowed
5)no spaces allowed.

now checking the login page with 1)username raje n$ and password with anusha
2)username:-raja_kumar password:-anusha friend
3)username:-&sarabha password:-karun
4)username:-rajendra_007 password:-anamica
now if u clearly observe the first 3 cases results to errors and only the fourth case will be correct and the home page of the application opens for the fourth case only.
like this checkling the given specifications of different parameters with all the possibilities is called as equivalenmce class partitioning.
