Hello I've got a petproject running, creating a DDNS that is. I've read up on it but before I start buying resources and build, I was looking for some feedback on my current thoughts.
My basic idea is,
1)Buy a domain from a registrar
2)Create two subdomains at my registrar for my dns/nameservers ns1.domain.com, ns2.domain.com (apparently two seems mandatory?)
3)Set my custom name servers at the registrar to ns1.domain.com and the alternative to ns2.domain.com
4)Create two Linux VPS, setup BIND9/DNS.
5)At my registrar, point ns1.domain.com, ns2.domain.com to my VPSbased DNS servers.
Now if i've understood everything right, I don't have to bother updating anything else at my registrar and I can
1)Point my www.domain.com to wherever I want by editing my DNS records on my own DNS servers
2)Create and handle an 'unlimited' amount of subdomains by editing my DNS records on my own DNS servers. (So I can give users their own subdomain to change the IP for)
Is this correct or are any of my steps flawed, do I have to do something additional?
Thanks in advance for any advice or insightful information!
