Abstract
Methods and systems for an IPv4-IPv6 proxy mode for DNS servers are provided. According to one embodiment, a DNS query is received by a network device from a dual-stack client. A determination is made the network device whether a first record type containing an Internet Protocol (IP) address for a server associated with the query exists within a DNS database of the network device. If the first record type exists for the server, then communication is enabled between the client and the server based on the first record type; otherwise it is automatically determined whether a second record type usable by the client exists for the server. Responsive to a determination that the second record type exists, data associated with the second record type is shared with the client by the network device to enable communication between the client and the server.
