DDOS protection from ISP side, UDP protocol, whitelist

Is it possible to ignore packets from ISP side which are incoming to my server?

Is possible this kind of situation ? :

I have white list of IP addresses.
I continually update white list and sends it to ISP(?).
ISP checks if UDP packet sender's ip address is on white list. If it is - ISP sends packet to my server. If it isn't, it blocks it so my bandwidth is not wasted.
