Written form of an informal pronunciation of don't know that is a reduction of do not know or does not know.
dunno
As with several other verbs in English that regularly do not require a pronoun, when the pronoun is not given, it is assumed to be I; all other pronouns must be given. It is never mandatory to drop I, although it is most common to do so when dunno is the only word in the sentence.
