An ISP publishes an IP address and a corresponding anonymous public key designating who is paying for it and for how long into the future it has been paid.
Is this enough rope to allow customers to swap IP addresses for their own privacy protection? A customer identifies himself to another by private key.
We assume there is a way, after a swap, for the ISP's routers to be appropriately updated. But a government could try to subpoena routing table information. Let's assume swaps occur frequently, so tables quickly become obsolete in the time it takes to process a subpoena.
