Abstract
A method and system for address server redirection for multiple address networks. A primary network address and an address of a secondary network address server are requested by a network device from a primary network address server. The address of the secondary network address server is requested in an option field in a request message sent to the primary network address server to request a primary network address. The request message may be sent through one or more routers. The primary network address is used by a network device to communicate with other network devices on a first network. The secondary network address is used by the network device to communicate with other network devices on a second network. For example, the primary network address may be a private Internet Protocol address or an Internet Protocol version-6 address and the secondary network address may be a public Internet Protocol address or an Internet Protocol version-4 address. The method and system may also allow existing primary network address servers such as Dynamic Host Configuration Protocol (“DHCP”) servers, and new secondary network address servers, such as Distributed Network Address Tr…
