The invention provides an inter network address resolution device between a non PTDN network and an PTDN network. In the device, the address retrieval between the module and the main control module to transmit data through the register, between the existing network address and public packet data network address parsing, it can ensure the accuracy of data transmission and correspondence; at the same time address set through the pre query parsing module address table storage module to realize the conversion between the current network address and public packet data network address, the existing network packets can be forwarded in a public packet data network, to connect the existing network and the public network to packet data. And the address retrieval module is based on the TCAM chip search architecture, using the TCAM internal algorithm and table management function. The network address resolution device of the existing network and the public packet data network can be cascaded so as to improve the accuracy and speed of the query and facilitate data updating at the same time.
