No, as far as I can tell, everything is acting as it should.
Hi Iām wondering if anyone has any insight about a somewhat related problem Iāve discovered with my new Connect Home hubs. The main hub seems to be flooding my pi-hole server with millions of requests in the last 24 hours for reverse DNS lookup. No idea why. ( [0.0.0.0.in-addr.arpa] and [0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa] ) I just bought these hubs and havenāt even moved my smartthings devices over from my V2 hub yet (because it sounds like I have to do it all manually) and yet the connect home hub is slamming my dns server with hundreds of reverse requests every second. I disabled the āsmartthings hubā feature for the connect home and itās still sending the constant dns requests. I Updated the firmware on the two connect homes as well and no difference. Any ideas would be appreciated. Sounds like this other person is having the same problem⦠https://us.community.samsung.com/t5/Smart-Home-Support/Connect-WiFi-reverse-dns-flood/td-p/1008496
I had something similar to that some time ago. It seemed to have something to do with the hub mistakenly looking up some Hue devices on DNS . It was about that time I stopped using the ST hub for most of my automation and moved to Homeseer instead. I still have the ST hub running for some routines that work on it, but not for any of my lighting.
Thanks Bill. I donāt actually have any Hue devices on my network and actually these new connect home hubs are only currently acting as a wifi network as Iāve disabled the smartthings portion of those hubs. Yet it seems to be flooding the dns server with reverse lookups. Maybe Patrick has some inside info about this or is there a better place to get directly in touch with Smartthings staff? I suppose I could just e-mail them directly but this problem seemed similar to the one Iām experiencing. Thank you
Unfortunately I wonāt be any help one this one. Anything Iāve ever worked on here (or even seen) gets turned off when you turn off the hub feature & I donāt have any contacts on the team that does the development for the ST Wifi itself. The problem mentioned above should now be fixed and itās code that is disabled when the hub feature is off. So, this thread is probably a red herring for the issue youāre seeing.
Okay thanks for the quick responses. Iāll try to hunt for an answer elsewhere then.
I turned on DHCP server on my pi hole as well and disabled DHCP on the router and configured router to advertise the pi hole DHCP. That way you donāt have to configure every client. I have about 80 devices so I just flipped the main breaker on the house to reset everything. Call me lazy.
I had something similar to your problem, the DNS was very strange and we changed IP addresses and providers, but these methods did not help us. It turned out that we kept a small hosting service for our site at home and it spoiled the dns addresses.
