While the above is technically correct, in his circumstance BGP is not an option. To do BGP you TYPICALLY need to own your IP address space in order to be able to advertise them successfully. He's talking about how many addresses his provider is going to give him so he doesn't have such addresses. Second, the address space he's talking about is so small that even if he does get addresses and providers who will do BGP, no one else will pay attention to his advertisements anyway. Each advertisement takes up expensive memory in core Internet routers and the larger network providers aren't going to spend lots of money so he can have redundant network providers. Don't go there.
