display in the jsp page but when I submit this form it is unable to
populate to the action form.

Your form bean should have an indexed property (see the Struts docs) of 
type IpAddress. Say you call this ipAddress, then your logic;iterate tag 
shoudol have id="ipAddress" and  your html:text tag should have 
name="ipAddress" indexed="true".
