Hmm... Even though similar issue was identified in 2003, looks like still there are devices in market with those old firmwares or similar behavior. sheesh !! :(
A long long time ago in a network far far away, one of our campus NTP servers was a machine under my desk. That machine was shut down around 2002/06/30 22:49 and we didn't re-assign the IP address ever since *because* it kept getting hit with NTP packets.. Yes, a decade ago. A few months ago I ran a test of how many things were still using it. In the first 15 minutes, 234 different IP's tried to NTP to that address, which has been a black hole for a decade. After 3 hours, I had almost 2,000 IPs. Interestingly enough, the *hostname* is still in use (by another machine under my desk) - and it gets near zero hits. So it's all hardcoded IP addrs not hostnames.
