Abstract
A network controller communicates a wildcard domain name defined by a tenant and IP addresses of data centers for which a tenant has configured that wildcard to network elements of a network fabric through which the data centers are accessible. Each network element creates a rule to forward DNS requests with FQDNs that match the wildcard to each data center IP address. When a network element receives a DNS request indicating a FQDN that matches the wildcard, the network element forwards the DNS request to each data center IP address. Each data center element associated with one of the IP addresses receives the DNS request and determines if the FQDN can be resolved to an IP address in that data center. Data center elements for which domain name resolution is successful notify the network controller, which onboards the resource corresponding to the FQDN in that data center.
