Object that describes a "location" on the Internet with sufficient detail that we can reasonably estimate an upper bound on the ping between the two hosts, even if a direct route between the hosts is not possible, and the connection must be routed through the Steam Datagram Relay network. This does not contain any information that identifies the host. Indeed, if two hosts are in the same building or otherwise have nearly identical networking characteristics, then it's valid to use the same location object for both of them.
NOTE: This object should only be used in the same process! Do not serialize it, send it over the wire, or persist it in a file or database! If you need to do that, convert it to a string representation using the methods in ISteamNetworkingUtils().
