DNS question

I have a hint record pointing to a name server that has not been used to several years. As I am changing providers, I need to try to delete this record. I think the appropriate question for this forum, is where should I go to research/ask this question? Replying to me off list is fine and I will share any answers, success or lack thereof if there is interest.
