Just because someone is telling you something you don't want to hear or don't understand is no reason to be so rude. If your network doesn't support host-masking, there is absolutely nothing you can do about it, apart from what has already been suggested, i.e. get a BNC account. A lot of networks won't allow you to connect via a BNC though, so it's up to you - live with it, or find another network that suits your requirements.
