I'm just getting started with DNS (I've used a CP to configure my nameservers). I just signed up for a VPSLink server that only provides one IP address. However, the GoDaddy control panel requires a domain to have two nameservers. I read "Traditional DNS Howto" to find out how to setup a master and slave nameserver. I'm just wondering, is is possible to set up a master and slave nameserver that both point to the same IP, as my VPS only provides one IP address?
