// 3.2.18 Object: Device
//
// This object provides information pertaining to the device through which the user is interacting.
// Device information includes its hardware, platform, location, and carrier data.
// The device can refer to a mobile handset, a desktop computer, set top box, or other digital device.
//
// BEST PRACTICE: There are currently no prominent open source lists for device makes, models, operating systems, or carriers.
// Exchanges typically use commercial products or other proprietary lists for these attributes.
// Until suitable open standards are available, exchanges are highly encouraged to publish lists of their device make, model, operating system, and carrier values to bidders.
//
// BEST PRACTICE: Proper device IP detection in mobile is not straightforward.
// Typically it involves starting at the left of the x-forwarded-for header, skipping private carrier networks (e.g., 10.x.x.x or 192.x.x.x), and possibly scanning for known carrier IP ranges.
// Exchanges are urged to research and implement this feature carefully when presenting device IP values to bidders.

	// Attribute:
	//   geo
	// Type:
	//   object; recommended
	// Description:
	//   Location of the device assumed to be the user’s current
	//   location defined by a Geo object (Section 3.2.19).

	// Attribute:
	//   dnt
	// Type:
	//   integer; recommended
	// Description:
	//   Standard “Do Not Track” flag as set in the header by the
	//   browser, where 0 = tracking is unrestricted, 1 = do not track.

	// Attribute:
	//   lmt
	// Type:
	//   integer; recommended
	// Description:
	//   “Limit Ad Tracking” signal commercially endorsed (e.g., iOS,
	//   Android), where 0 = tracking is unrestricted, 1 = tracking must
	//   be limited per commercial guidelines.
	Lmt *int8 `json:"lmt,omitempty"`

	// Attribute:
	//   ua
	// Type:
	//   string
	// Description:
	//   Browser user agent string. This field represents a raw user
	//   agent string from the browser. For backwards compatibility,
	//   exchanges are recommended to always populate ‘ua’ with the
	//   User-Agent string, when available from the end user’s device,
	//   even if an alternative representation, such as the User-Agent
	//   Client-Hints, is available and is used to populate ‘sua’. No
	//   inferred or approximated user agents are expected in this field.
	//   If a client supports User-Agent Client Hints, and ‘sua’ field is
	//   present, bidders are recommended to rely on ‘sua’ for
	//   detecting device type, browser type and version and other
	//   purposes that rely on the user agent information, and ignore
	//   ‘ua’ field. This is because the ‘ua’ may contain a frozen or

	//   the bid request, ‘sua’ should be considered the more accurate
	//   representation of the device attributes. This is because the ‘ua’
	//   may contain a frozen or reduced user agent string.
