Description

I recently played around with DNS over HTTPS.

I found that it's a little bit tricky to generate the appropriate resource using the Resolv::DNS::Resource hierarchy.

Here is what my code ended up:

        if klass = Resolv::DNS::Resource.get_class(answer["type"], resource_class::ClassValue)
          if klass < Resolv::DNS::Resource::DomainName
            resource = klass.new(Resolv::DNS::Name.create(answer["data"]))
          else
            resource = klass.new(answer["data"])
          end

It would be nice to have a simpler interface, e.g.

        if klass = Resolv::DNS::Resource.get_class(answer["type"], resource_class::ClassValue)
          klass.create(answer["data"])
        end

In this case, the Resource#create method would take a data string and convert it to a name if required.

The base resource class could just have alias create new, while the DomainName class could have:

def create(data)
  self.new(Name.create(data))
end

Or something like that.
