I think the address thing has to do with the Mid Life Crisis and "moving on" although that is no acceptable excuse. Many exes (including mine) did the same but when they have your child with them - no way that is acceptable.
Although, as Eric says - you can find out easily enough. Just some of the weirdness we have to deal with.
I moved away long after my ex moved out. He had never given me an address or an email when he left. I do get an occasional text these days. But he was abusive so I did not give him MY address. I do have his adult disabled son living with me. But I communicate with him and have always made my son available to him for visitation. I just want it in a public place. I think I have good reason for this. When he drinks - there is no telling what he would do. I choose to live in peace.
