I'm not sure what purpose someone would need to "track down" someone's home address for any reason?

Perhaps IT can speak to what their intentions are. I get the curiosity, as I said I did something similar when i was quite young but I know better these days and I wouldn't want to invade a T's right to privacy. This is someone I need to be a professional and I want to keep that relationship in the office— so it can be what I need it to be.
