As the requirement, I need to let user fill in multiple ip addresses, current thought is: put 4 text boxes separated by dot(.) in one line, but need more work in backing bean to convert four parts to ipaddress and vice versa.
If you dig around, you might find some sort of AJAX control for IP addresses, but there's nothing wrong with your idea. You can use a 4-element array to hold the 4 parts of the IPV4 address. The String split() method can help you break the address parts out from a string.
