We describe an IP-layer anonymizing infrastructure, called ANON, which allows server addresses to be hidden from clients and vice versa. ANON uses a network resident set of IP-layer anonymizing forwarders that can forward IP packets with encryption and decryption applied to their source and destination addresses. Using ANON, a client can send and receive packets to and from application servers without knowing their IP addresses. We have designed and implemented a laboratory testbed for this

We have implemented a laboratory testbed for ANON at Harvard. The testbed incorporates the countermeasures mentioned above. For ease of use, the testbed also includes
