Abstract

Knowledge associated with an address of a first IP type may be mapped to an address of a second IP type. In response to receiving, at a first IP endpoint type, a request from a client associated with a first and second IP address type, a first address of the first IP type associated with the client is recorded. A unique identification of the request is generated. The unique identifier and instructions to make a second request to a second IP endpoint type are sent to the client. The second request, that includes the unique identifier and corresponds to the second IP address type associated with the client, is received at the second endpoint. Both the first address and the second address are determined as corresponding to the client by determining that the unique identifier was used in both requests. The first address is mapped to the second address.
