Hm... I'm feeling stupid myself now... I reread all your posts and nowhere did you say you were getting a bot to op you. For some reason, I was thinking you had a bot that was opping you if you had the correct hostname. None of what I said will help you. I'm sorry.
If I were you, then... I'd contact your ISP and see what they can tell you. It could be that their DNS information is messed up and that's why it won't resolve.
Maybe someone else has a better suggestion.
