39 * Network size estimate sent from the service
40 * to clients. Contains the current size estimate
41 * (or 0 if none has been calculated) and the
42 * standard deviation of known estimates.

53 * The current estimated network size.
58 * The standard deviation (rounded down
59 * to the nearest integer) of size
66 * Network size estimate reply; sent when "this"
67 * peer's timer has run out before receiving a
68 * valid reply from another peer.

84 * of timestamp and the initiator's public
