Abstract
Methods, apparatuses and systems directed to facilitating transitions from IPv4 to IPv6 networks. In particular implementations, the invention facilitates or enables accessibility of network application services between IPv4 and IPv6 hosts, or traversal of network paths including both IPv6 or IPv4 domains. Particular implementations of the invention are directed to selective mapping of network layer addresses between IPv6 and IPv4 protocols and Domain Name System records under one or more policy controls. Other implementations of the invention are directed to a proxy-to-proxy based tunnel architecture allowing hosts implementing a first network layer protocol, such as IPv4, to traverse a network implementing a second network layer protocol, such as IPv6.
