A domain name is a unique identifier, usually assigned to a specific domain by the Registrar.
The registrar assigns the domain name to the domain owner, who then maintains the name.
In this way, the name is the “owner” of the domain, and the domain is “managed” by the domain registrar.
In some cases, the domain may be managed by the Registrant (the person who maintains the domain) or the domain itself (the domain administrator).
However, this model has its limits, as the Registrar may be unable to determine the name of a domain at all.
The domain administrator must use a domain registrant’s information to determine whether a domain has been registered.
To make this process easier, DomainMarket.com provides the following two methods for determining whether a given domain has a registered name: First, Domain Manager can use the following information to find out the name associated with the domain: The domain’s IP address.
The email address of the Domain Manager.
For example, if a domain is registered at domainmanager.com, then the domain manager’s IP is 172.16.1.1, and that domain is the domain 172.17.1 or 172.18.1 (depending on the DomainManager configuration).
For more information, see Domain Manager and IP address information.
Domain Administrator can use Domain Manager to determine if a given IP address is associated with a domain: If the domain’s hostname matches the hostname, Domain Administrator will send the domain administrator’s name and email address.
Domain Administrators must be able to verify this information using a domain’s DNS record.
For more details, see DNSSEC and DNS record validation.
If the hostnames match the email addresses, Domain Administators will receive a response to their mail.
If this response contains the domain [email protected], then Domain Administrator should send the email address to Domain Administrator.
If it does not contain the domain domain admin, then it’s unlikely that Domain Administrator’s response will contain the correct information.
If Domain Administrator does not send a response, DomainManager may be able determine whether the domain has an IP address that is associated in the DNS with a different domain name.
This can be done using the IP address of Domain Manager itself, or by using the DNS lookup table.
DNS lookup tables are available in both Windows Server 2008 and Windows Server 2012.
DomainManager provides a DNS lookup feature for each domain name it manages.
Domain Manager will use the lookup information to make a DNS query to resolve the IP addresses of all domains it owns.
Domain administrators can use this DNS lookup information as a reference for determining the domain names of their domain names.
If a domain owner can be found on the DNS, then domain administrator can check if the domain uses the same IP address as a domain they own.
If not, then there is an IP mismatch.
The Domain Administrator that maintains the domains can also use the DNS for checking domain ownership.
Domain Management will display the IPs of the domains that Domain Manager manages, and Domain Manager must be capable of determining domain ownership from this information.
However, Domain Management is still unable to know if the domains in question are owned by the same registrar or the same administrator.
Domain managers can use a Domain Manager service to determine which domain names belong to which registrar, if the registrar is in a public registry.
If both registrars are public, then they must use the same registry, and both registrants must be available for queries.
If one registrar does not provide public access to domain management, then either registrar must use one of the public registry addresses.
For this reason, domain administrators should only allow domain management from public addresses that are accessible to all domain users.
In most cases, it is recommended that domain administrators allow domain names from registrar A to registrar B to be accessed.
If domain owners want to add domains to their domains, then Registrars should provide the domain owners with a list of domain names that they want added.
Domain owners can then use the public registrar registry address to add domain names to their own domain.
Domain management allows domain administrators to make queries to domain owners.
Domain Maintainer will not use the name-based DNS queries from Domain Manager, since Domain Manager queries do not contain domain information.
For information on how to query domain name servers, see How to use DNS queries.
Domain Admin can use an automated query service to query the domain database for information on domain owners, including names of domains they own and the IP and hostname of domain owners who are domain administrators.
For a complete list of automated queries available, see Automated Domain Manager Query.
Domain Administration can use Determining Domain Ownership to query Domain Manager for information about domain owners that are domain managers.
This is an automated service that can be run by a Domain Admin, Domain Master, or Administrator.
