			This packet is sent by a leaf that is firewalled to one of its hubs that it will use to proxy

			=== Receiving ===

= /QKR - Query Key Request =

The query key request asks a destination hub to provide a query key that the
requesting node can use to securely perform queries. This mechanism ensures that
the network cannot be used to direct unsolicited packets to external hosts.

== Sending ==

A query key request should be sent to a hub via the connectionless transport if a key
is not already available for that hub for the local node address, or if a previously
acquired key no longer works or has expired. There is no reason to request a query
key via a TCP link.

== Receiving ==

Upon receiving a query key request, a hub should respond with a query key answer
(/[[QKA]]) packet if it is willing to supply a query key. The answer packet should be
dispatched to the return address indicated in the request packet only, and the
allocated key should be locked to that address.

== Payload ==

This packet has no payload at the current time.

== Children ==

The QKR packet has one child packet defined at the current time:

* /QKR/RNA

== /QKR/RNA - Requesting Node Address ==

A query key may be requested for a node address other than that of the sender, for
example when a UDP-firewalled leaf node wishes to acquire a query key for a remote
hub that it will route through a locally connected hub. In this case it must request a
query key for the node address of a connected hub.

=== Sending ===

This child is required to ensure that the sender knows its address.

=== Payload ===

The network address of the requesting node. See [[Datatypes]] for more information.

=== Children ===

This packet has no known children at the current time.
