Incorrect Hostname Reporting?

    One possibility is somehow the devices changed IP addresses, and for a moment, the old IP was tied to a new device.  Are you using the production 1.961 code? or the beta 1.963?

    Production code. Both devices are DHCP, but I don't think either of them have been rebooted or have renewed leases in a long while. Ill keep an eye on them...

    Same issue here:

    a number of devices are listed under their MAC-address vendor name instead of their hostnames.

    I also confirmed that that reverse dns lookup resolution works properly so if firewalla were to use the name provided by the router it wouldn't have any issues:

    nslookup 192.168.0.240 192.168.0.1
    240.0.168.192.in-addr.arpa name = foo.bar.mooo.com.

    setup:

    • router(with dhcp & dns ) = ASUS RT-AC88U = 192.168.0.1
    • firewalla plugged straight into the router running "experimental simple mode"
    • note: some devices are plugged into a TP-link switch in turns plugged into the ASUS router (as opposed to get plugged directly into the router's ports or wifi)

    Depends on the host, it may take a while for the true name to show up... we have 6 different mechanisms to "guess" the name of the device.

    That's interesting, can you please expand on these 6 methods?

    I would have expected to rely on the DNS from the DHCP server to be one of the first.

    @rodrigo, for that send us a email, it may require digging.  Also, see if this persists, and also check your DHCP lease times. (adjust them to be longer if you have short ones).  

    This usually happen when devices changes IP ...
