Can I follow the step of How To Run Your Own DNS Servers (Primary And Secondary) With ISPConfig 3 (Debian Squeeze)? And I find that the topic is for two different IP....I only have public ip, how can I set up my server? I do want to use ns1.xxx.com and ns2.xxx.com for dns server as a same ip. Only create the dns record or some else? Thank you very much!
