Answer 1

I do not know about HiddenFor because I have not use it before.
How I hid fields before was like this:
#Html.TextBoxFor(model => model.IPAddress, new { #class = "sr-only", #type = "hidden" })
You can add the bootstrap class sr-only to make sure it is hidden.
Make sure you check your browser inspector to see whether the hidden field has a value.
If posted and is still not saving, then try to assign the IpAddress identity to the form field value before saving it like this:
cmp.IPAddress = Request.Form["IPAddress"];

Answer 2

Store IP address as a string instead of Int32
Please use code from here to get IP Address
