I want to use my internet connection to host two personal websites (two different domains). I would also like to host mail for these domains.
This requires hosting my own name server. In the nameservers configuration section on my registrar's website, it requires two name servers. Probably for reliability?
I have previously used zoneedit.com, and they provided me with two nameservers but I would like to host it myself, save myself some coin, and learn how to configure bind for experience.
I only have one internet connection, and only have the ability to host one nameserver. What are you supposed to do with the second name server?
