    Default Strange internal IP address

    Hi. I've this network layout:

    There are n. 1 internal network and N. 4 internal VLANs.

    If I look to the IPs released by the DHCP Server on the internal network (10.10.10.xxx) I see the correct IP addresses on the correct subnet.

    But with my big suprise, I see on the same internal network may strange IP addresses on different and strange subnet:

    It is important to specify that all clients are wireless clients connected to the internal network via WiFi access points.
    Any idea?
    Thanks in advance.

    Default

    169.x.x.x is a default address when a PC can get an IP. Sometimes it's just timing as the ARP table populates before the device gets a real IP.
