It should not be in any IPv6 packet. It has to be in an upper layer 
protocol.

In worst case. Host should have an option to sending location update - 
probably not in IP headers, but upper layer protocol.

I suggest an upper layer protocol. Something like HTTP, TCP or UDP option. 
The server can initiate a carry, and a client can decide to answer with 
location information.

I prefer application and at most the transport layer protocol extension.
