MobileFuse requires ip or ipv6.

What it means

MobileFuse requires ip or ipv6. This check applies to the selected vendor contract and integration direction.

Why it matters

The declared profile checks the published partner contract alongside canonical OpenRTB. It does not verify runtime approval or account configuration.

How to fix it

Supply the missing information through the documented field or permitted alternative for this direction.

Example that trips it

{
  "id": "depth-request",
  "imp": [
    {
      "id": "1",
      "tagid": "placement-1",
      "banner": {
        "w": 320,
        "h": 50
      }
    }
  ],
  "app": {
    "bundle": "com.publisher.game"
  },
  "device": {
    "ua": "Mozilla/5.0",
    "lmt": 0
  }
}

Profile mobilefuse, OpenRTB 2.6-202606. The fixture asserts openrtb.profile.mobilefuse.device_address_required at device.ip.
