This disclosure describes techniques for performing domain name system (DNS) support on public resolvers. For instance, an electronic device may send a query to a local DNS resolver. The electronic device may then receive an answer from the local DNS resolver that includes a pattern. Using the answer, the electronic device may generate a DNS packet that includes at least the answer and a query for a first Internet Protocol (IP) address associated with a first IP version, such as IPv6. The electronic device may then send the DNS packet to a public DNS resolver. Using the DNS packet, the public DNS resolver may generate a synthesized IP address associated with the first IP version. For example, the public DNS resolver may identify a second IP address associated with a second IP version, such as IPv4, and generate the synthesized IP address using the second IP address and the answer.
