Do I need a DNS zone and setup the DNS server?

[olieb]

I build a webserver following the HOWTO:http://www.howtoforge.com/perfect-se...04-ispconfig-3
I have my own domain name registered 1 month ago at register.com and it is tied into my static public IP. My intention is to host some more websites for others.
The command dig mx mydomain.com shows:

xxx@ubuntu:~$ dig mx mydomain.com

; <<>> DiG 9.7.3 <<>> mx mydomain.com
;; global options: +cmd

Should I still use the DNS server and create the DNS records for my domain using ISPConfig, or is that not needed?
If I don't do this can I then still create domains names for others using my server?

Please advice.

p.s. Yes I am still learning .

You dont need to run your own dns server when you use the dns of your registrar.

Thanks for the reply.

What if I am going to host others on my server? How does it work if they have no domain name, can I create one for them if I use the DNS?
What if they have a domainname, how can their IP be redirected to my server?

If they dont have a domain, they will have to register a domain name or you offer them a subdomain of your own domain name. You can do this with the dns server of your registry or run your own dns server. Thats totally up to you. You will also find some more detaled instructions on how to create DNS records in the ISPConfig 3 manual.
