Bind

Bind allows to configure the junction between an IP and a domain name via a domain name server.

CentOs configuration

Configure the named.conf and add a zone "point.pt"

/etc/named.conf
options {
        directory "/etc";
        pid-file "/var/run/named/named.pid";
        listen-on {
                128.177.28.198;
                127.0.0.1;
        };

        allow-query {
                localhost;
        };
        allow-transfer {
               localhost;
        };

        check-names     master          warn;
        check-names     slave           warn;
        check-names     response        warn;
        };

zone "." {
        type hint;
        file "/etc/db.cache";
        };

zone "point.pt" {
        type master;
        file "/var/named/point.pt.hosts";
        allow-transfer {
                207.126.122.215;
                66.249.3.204;
                };
        };

Then create and edit the /var/named/point.pt.hosts file:

@	IN	SOA	pointpt.user.openhosting.com. mr.hugo.gomes.gmail.com. (198254559	10800	3600	604800	38400 )

@            IN   NS      dns.point.pt. 
@            IN   NS      ns1.openhosting.com. 
@            IN   NS      ns2.openhosting.com. 

@            IN   MX   10   mail 
      
@            IN   A      128.177.28.198

dns.point.pt.          IN   A      128.177.28.198 
ns1.openhosting.com.   IN   A        207.126.122.215
ns2.openhosting.com.   IN   A        66.249.3.204

www.point.pt.      IN   CNAME      dns 
mail.point.pt.      IN   CNAME      dns 
test.point.pt.      IN   CNAME      dns 

128.177.28.198.point.pt.   IN   PTR      dns
207.126.122.215.openhosting.com.   IN   PTR      ns1
66.249.3.204.openhosting.com.   IN   PTR      ns2

Then add the /var/named/point.pt.hosts file in the secondary dns servers as well. We asked to Openhosting to do it, and they kindly did.
