US11095711B2 DNS Resolution of internal tenant-specific domain addresses in a multi-tenant computing environment
A method and associated systems for a multi-tenant DNS mechanism. A multi-tenant computing environment hosts multiple private overlay networks, each of which comprises one tenant's domain. A multi-tenant DNS agent receives a DNS request to resolve a domain address located within the multi-tenant environment.
