4.2.1. <del> The ADDRESS_ASSIGN capsule allows an endpoint to inform its peer that it has assigned an IP address or prefix to it.  The ADDRESS_ASSIGN capsule allows assigning a prefix which can contain multiple addresses.  Any of these addresses can be used as the source address on IP packets originated by the receiver of this capsule.  This capsule uses a Capsule Type of 0xfff100.  Its value uses the following format: </del>  IP Version of this address assignment.  MUST be either 4 or 6. 4.2.2. <del> The ADDRESS_REQUEST capsule allows an endpoint to request assignment of an IP address from its peer.  This capsule is not required for simple client/proxy communication where the client only expects to receive one address from the proxy.  The capsule allows the endpoint to optionally indicate a preference for which address it would get assigned.  This capsule uses a Capsule Type of 0xfff101.  Its value uses the following format: </del>  IP Version of this address request.  MUST be either 4 or 6. 4.2.3. <del> The ROUTE_ADVERTISEMENT capsule allows an endpoint to communicate to its peer that it is willing to route traffic to a given prefix.  This indicates that the sender has an existing route to the prefix, and notifies its peer that if the receiver of the ROUTE_ADVERTISEMENT capsule sends IP packets for this prefix in HTTP Datagrams, the sender of the capsule will forward them along its preexisting route. Any of these addresses can be used as the destination address on IP packets originated by the receiver of this capsule.  This capsule uses a Capsule Type of 0xfff102.  Its value uses the following format: </del>  IP Version of this route advertisement.  MUST be either 4 or 6. 4.2.4. <del> The ROUTE_WITHDRAWAL capsule allows an endpoint to communicate to its peer that it is not willing to route traffic to a given prefix.  This capsule uses a Capsule Type of 0xfff103.  Its value uses the following format: </del>  IP Version of this route withdrawal.  MUST be either 4 or 6.
