I would like to start DNS service. I have to offer minimum 2 NS. Is there any software for managing DNS records? How to make Master and Slave NS?
Yes, there are software available for managing DNS. In windows server 2003, you can use MS DNS server or SimpleDNS server. If you use Linux server then the BIND server is good for managing DNS.
A decent application to manage DNS records that will be published on Bind DNS servers is Nixu NameSurfer. -Raymond
I mean web based software where clients will manage their domains. How to "synchronize" Master and Slave NS?
Be careful with your terminology. Do you want 2 DNS servers managed by an easy to use GUI, or be providing both Primary and Secondary DNS hosting services? Also, it's not clear if this is just for you, or if you want to be selling this as a service that you provide to others. If it's just you a simple master/slave setup and you editing bind files should be OK. -Raymond
Well. Many domain registers need 2 name servers. DNS records should be same on both NS. So, is there any GUI (php WEB based). Simply: I want to do something like no-ip or dyndns or domainsite.
