    The IP Precedence bits, like 802.1p CoS bits, allow for only the following 8 values of marking (0–7):

    – IPP values 6 and 7 are generally reserved for network control traffic such as routing.

    – IPP value 5 is recommended for voice.

    – IPP value 4 is shared by videoconferencing and streaming video.

    – IPP value 3 is for voice control.

    – IPP values 1 and 2 can be used for data applications.

    – IPP value 0 is the default marking value.
