All resource records added to a name server have a domain suffix related to a name server zone. Typically, an enterprise's domain suffix is something like mycorp.com. Subdomains can exist under a domain, which have the subdomain name added before the parent's domain suffix, such as raleigh.mycorp.com and austin.mycorp.com.
The domain suffix of the resource records that ADNR creates is determined by the domain_suffix keyword of the zone keyword of the dns statement in the ADNR configuration file.
