Owing the domain name and having it resolvable via DNS are two different issues. The ISP or somebody outside your local network has to provide the mapping from FQDN to public IP address.
While different issues, I would say that they are related. One can hardly have a public DNS to map a FQDN that you don't own to your address. Not honestly.Public DNS
is a keyword here. It must be a publicly known name server that tells everybody that a name corresponds to an address. We (every Inet user) do not know your IP nor know that it has a DNS that resolves a name that points yo your IP. Of course, if every public DNS would know that your name is resolved by a specific public authoritative DNS, then they would redirect the queries to that server. That is how DNS works.
You did buy the domain name from somewhere. Why doesn't that party maintain a DNS? You did say that you did contact some support. A virtual server farm owner? They must use an ISP, and ISP (Internet Service Provider -- the chaps that "own" the outbound cable) usually do have a name server.
There is a DDNS (dynamic DNS
) too. That essentially allows a client to update his own record within a remote public DNS.
Be it static DNS or DDNS, there must be someone that you can contact and ask to add your FQDN/IP to their table.
