Q: Why is AppleTV trying to take my IP address?

My MacBook Pro stalls during browsing and has trouble trying to resolve hosts. Looking in the console messages I noticed the following lines.

 

9/23/14 12:53:10.961 PM configd[26]: DHCP en1: defending IP 192.168.1.15 against BonjourSleepProxy 58:55:ca:26:bf:ad 1 (of 5)

9/23/14 12:53:11.000 PM kernel[0]: en1 duplicate IP address 192.168.1.15 sent from address 58:55:ca:26:bf:ad


That MAC address belongs to my AppleTV. The AppleTV was configured to use DHCP.


I changed the AppleTV to use a fixed IP address. I am still having the same issue. Now I see the following messages in console.


9/26/14 10:28:14.703 PM configd[26]: MANUAL en1: defending IP 192.168.1.50 against BonjourSleepProxy 58:55:ca:26:bf:ad 1 (of 5)

9/26/14 10:28:55.000 PM kernel[0]: en1 duplicate IP address 192.168.1.50 sent from address 58:55:ca:26:bf:ad


Why is the AppleTV doing this? Any ideas?

    Both Macs are updated to 10.10.1. I do not have any AirPort base stations.

    The problem is with Apple's Bonjour Wake on Demand Sleep Proxy, see About Wake on Demand and Bonjour Sleep Proxy - Apple ....

     

    The thing is you don;t need to have an Airport router, if there is no Airport router then the Apple Tv will take over the function of handling this.  

     

    See Shared name of Mac keeps changing for a discussion of the problem that some of us have been experiencing since Yosemite came out. It appears that 10.10.1 fixed the problem (at least for me) but after a week of no name changes it appears to have happened again but I can;t be sure something else did;t trigger it.

     

    One thing to keep in mind  that while it is annoying it does not usually cause the network to malfunction, at least that was true in my case. Hopefully Apple is looking into this and a permanent solution will be released.

    Well for me, it makes one computer on the network completely unusable as it struggles to fight off the AppleTV.

     

    So for now, my AppleTV is dead to me. It is unplugged and will only be plugged in on the rare instances when I need it.

    Did you look through the thread I referenced? If you turn off Wake for network access in the system(s) it should stop trying to rename.

     

    BTW how does this make the computer unusable? In all cases I've seen there is really no impact to the system or the network. Perhaps you have a different  problem. Again try turning off the Wake for Network Access and turn off any sharing in the system that is unusable and see if that makes a difference.

    I looked through the thread. I don't think that is an issue for me. I don't care if my computer keeps incrementing the number. I turned off the 'Wake for network access' since I don't really need that anyway.

     

    The AppleTV makes the Mac unusable because the Mac can no longer get to the network. The IP address is eaten by the AppleTV.

    . The IP address is eaten by the AppleTV.

    Not really sure what that means.

     

    This error message

    9/26/14 10:28:14.703 PM configd[26]: MANUAL en1: defending IP 192.168.1.50 against BonjourSleepProxy

    is caused as it says by the BonjourSleepProxy running in the Apple TV. If no systems have Wake for network access set then then will not register with the Sleep Proxy and the issue should not occur.  You should look at the Apple document on the Sleep Proxy to get an idea of what it is for.

     

    Are you saying that even with Wake turned off and no sharing you are getting this error message? It should't  be and if you are you should contact Apple and file a bug report.

     

     

    I don't think that is an issue for me.

    Well it is possible this is something different but unlikely.

    In regard to "The IP address is eaten by the AppleTV"... The Mac which is spitting out the error messages can not connect to the network. Therefore that Mac is pretty useless.

     

    I have disabled the option in the Macs and powered on the AppleTV. I will see if this temporary workaround works or not.

     

    The bottom line is that Apple needs to fix this issue. I am a long time Apple user and advocate. I think issues like this should never happen but if they do, they should be resolved quickly. A less technical user wouldn't go digging for possible solutions.

    I agree, been fighting it myself since Yosemite was installed but luckily for me the systems and network remain useable. Looked like 10.10.1 fixed it but now I'm not so sure, had some strange results after the upgrade but haven't had the time to look into it. 

     

    In your case as the network (or at least that system) becomes unusable I'd look to see if the only issue is the Bonjour Sleep Proxy, You might have other issues.  Look to see if you are  getting the defend message if the problem reoccurs.

     

    good luck
