Take full control of your domains. Custom DNSSM allows you to control an entire domain through an intuitive web-based interface - you can even register the domain if you don't already own it. Use Secondary DNS if you want to run your own nameserver, but still take advantage of our world-class DNS redundancy.
We also provide domain registration services - you can buy your domain right here, or transfer your existing domain to us and consolidate all of your services to one place. Domain registration is fully integrated with our Custom DNSSM management service.
If you don't want the expense or complexity of your own domain name, our Dynamic DNS and Static DNS services give you a new name like yourname.dyndns.org, on one of our 43 domains. Best of all, Dynamic DNS and Static DNS are free for up to 5 hostnames.

kann mir das mal jemand übersetzen.

meine englischkenntnisse reichen dafür leider nicht aus.
ist eine subdomain bei www.dyndns.org wirklich kostenlos?
kann ich über eine solche auch auf meinen webserver zugreifen.
die routingsache ist mir im moment schon klar, zwecks portweiterleitung usw. (netgearrouter rp614)
