Jaapie,
I can understand some spoken Dutch because I lived in Aachen for awhile, but I cannot write it.
To control outside DNS, you need a company/service. I do not know about most services, but for $35/year I use EasyDNS (eashdns.com). There are cheaper places, but EasyDNS will catch all my email if we have a (power) outage... and send the email to the SME later. Other people will probably suggest different services. I think godaddy.com does DNS
