Netgear, at one point, also decided that hard-coding an IP address (for NTP, not DNS) was the best solution [0].

- Rychard 6y agoAs opposed to? I thought you had to specify your DNS server as an IP address. How would it resolve itself?

- bsagdiyev 6y agoSony did the same thing with a Blu-Ray player for NTP, effectively DDoSed that particular box because they also didn’t think to stagger the polling so like clockwork millions of consumer devices would check in at the same time nightly. From what I gathered from the electronics guys a few floors down they eventually resolved that in later revisions, or so I was told.
- lozaning 6y agoI worked on an IoT platform for a while that struggled with this. Our workaround was to tell support to tell people to not set automations to run on the quarter, half, 3 quarters or hour mark. Something set to run at 7:14 or 7:16 PM would run every night, something set to run at 7:15 was a crapshoot.
