			== /QH2/G1 - Gnutella-Relayed Query Hit ==

			When present, this child indicates that the /QH2 has been synthetized from a Gnutella Query Hit by the relaying Ultrapeer.

			Some Ultrapeers on Gnutella which connect as leaves to G2 can act as a '''hub-leaf''': the Query Hash Table (QHT) that they send to their G2 hubs are actually the concatenation of all the leaves they have + their own. Each /Q2 they receive are translated as a Gnutella query, then forwarded to all the Gnutella leaves. Query Hits that come back are then translated into a /QH2 to be processed correctly by the querying node. This hit can be delivered directly by UDP or relayed back to the sending hub.

			The presence of /QH2/G1 indicates to the receiving G2 node that this hit was relayed from Gnutella. Therefore, one of the /QH2/NH children will point back to the Gnutella Ultrapeer which acted as the gateway. Other /QH2/NH, if present, are the Gnutella push-proxies that were possibly present in the Gnutella hit.

			The hop count is set to '''1''' by the relaying Gnutella node to further indicate the relaying activity that took place.

			=== Sending ===

			This child is included by the relaying Gnutella Ultrapeer to indicate that the message was synthetized from a corresponding Gnutella hit, and that some of the original information may have been lost.

			=== Receiving ===

			When this child is present, the processing node can determine that the node serving the resources is a Gnutella host.

			All the /QH2/NH children refer to Gnutella nodes, and therefore should not be sent a /PUSH message but rather a Gnutella PUSH to be on the safe side (although the nodes may also understand /PUSH because they support G2, this is not guaranteed, whereas Gnutella support is implied by the presence of this G1 child).

			=== Payload ===

			No payload is defined at the current time.

			=== Children ===

			This packet has one child defined at the current time:

			This packet has no known children at the current time.

			== /QH2/HN - DNS Host Name ==

			This child conveys the DNS host name of the servent. This is useful when the host has a dynamic IP address that can change over time, letting others know how they can recompute your IP address through a DNS lookup when the connection to the specified address (IP and port) is no longer working properly. The port is not present here, since that is not supposed to change.

			=== Sending ===

			Send this child if you have a dynamic IP address and you know your DNS host name. This cannot be automatically computed and requires user input.

			=== Payload ===

			The host name of the host, as a string, with no trailing NUL (since the payload only contains the name). For instance, "g2host.example.com".

			=== Children ===

			This packet has no known children at the current time.

			== /QH2/TLS - TLS Support ==

			When present, this child indicates that the servent supports TLS connections.

			=== Sending ===

			Send this child if you are capable of initiating and receiving TLS connections.

			=== Payload ===

			No payload is defined at the current time.

			=== Children ===

			This packet has no known children at the current time.

			== /QH2/BH - Browsable Host ==

			When present, this child indicates that the servent supports Browsing.

			=== Sending ===

			Send this children if you are capable of serving browsing requests using the <code>application/x-gnutella2</code> Content-Type.

			=== Payload ===

			No payload is defined at the current time.
