No. IP address is the address used at the Network layer (Layer 3 in the OSI Refference model) while UDP works on the Transport layer (Layer 4), and a port number is here added to the IP address. So the full Layer 4's address is something as IP address:port number.

Think about postal addresses, something as "Walnut Street 12". Let IP address is the name of the street (in this case Walnut Street) and the port number is the number of house in this street (12). How to obtain the street name from a number 12 only?
