Again, I am not 100% familar with dyndns's Terms of Services. I do not know if you have a free or paid account with them, it matters in what TOS you fall under. As long as dyndns has the correct ip address in their database and are willing to serve that data, yes you could reach your web services via feldland.dyndns.org and test-feldland.dyndns.org. You may have to adjust your virtual host settings accordingly, but that is outside the scope of this list.

Problem with name resolving
Hi All, i have a private Network with a Debian Lenny Server/Router and the Services BIND9.7.3(DDNS)/DHCP4.1.1/PPPOE3.8/CUPS1.4.4/APACHE2.2.16 and Kernel 2.6.37.2. My Problem is that he can not resolve himself and regardless from which PC i do a ping i can not resolve my two name-based-virtual hosts. Furhter on i do not know how to setup my network at the best dynamically? When my pppd program dials in it gets two nameservers which he shall save in /etc/resolv.conf or not? When i save this two nameservers in /etc/resolv.conf i have problem too resolve my local network, but when pppoe does not save these two nameservers, i have problem to resolve internet names from my server view. Further on i can not reach my two virtual Apache Hosts www.feldland.dyndns.org, test.feldland.dyndns.org, but i can reach feldland.dyndns.org which leads me to test.dyndns.org.

Don't really care about ping outputs. You are asking about name resolution with your bind server. I don't care about ping because it uses some methods that are outside of DNS. Like checking your hosts file and adding the search domains. I will only comment on DIG outputs. NSLOOKUP is better than PING, but does not post as much diagnostic output as DIG.

I don't know if dyndns.com will allow you to create cname entries in their zones. They will if you have a hosted domain name there. You need to open udp and tcp port 53 only if you need to make your dns server available to the public Internet. If it's only for internal use, no. And besides, if you want to run a public name server, it needs to be on a static IP address and not on a dynamic ip address.
