Your answer is Direct address...this is why...
direct address is the name of the person (normally) who is being directly spoken to. It is always a proper noun.
A participle phrase is a verbal ending in -ing (present) or -ed, -en, -d, -t, -n, or -ne (past) that functions as an adjective, modifying a noun or pronoun. A participial phrase consists of a participle plus modifier(s), object(s), and/or complement(s).
Prepositional phrase a modifying phrase consisting of a preposition and its object.
Indirect address is a address that serves as a reference point instead of the address to the direct location
