Techniques for dynamic configuration of a domain name system (DNS) server in a virtual network environment are described. In one example embodiment, DNS rules are configured using virtual machine (VM) inventory objects and associated DNS names. Further, the configured DNS rules are transformed by replacing the VM inventory objects in the configured DNS rules with associated Internet protocol (IP) addresses using an IP address management (IPAM) table or a network address translation (NAT) table and the DNS names in the configured DNS rules with modified DNS names using a zone table and a view table. Furthermore, the transformed DNS rules are sent to the DNS server for performing domain name resolutions associated with multiple VMs running on a plurality of host computing systems in a computing network.
