I wonder if it's really a MUST to have at least 2 public IP's to successfully install and run BIND9 DNS server on Ubuntu Linux.
Well, my ISP won't let me get 2 IP's. They say that PPPoE that they use won't allow it. Therefore, I would be needing two separate servers in two different locations, wouldn't I?
The reason why I'm asking... See, my domain name's registrar handles for free DNS lookups for my site. Actually, their DNS service is pretty good (it's GoDaddy).
Let me rephrase my question though... Is there a sure way to bypass that 2 DNS server limitation? Let's say, I could add as a secondary DNS server for my domain name my ISP's DNS server' hostname or even Google's. Or it's gonna fail?
Frankly, maybe I shouldn't even bother running my own DNS in SOHO environment with just one site. But I kinda wanted at least to try (out of curiosity, if you will...).
