However, I don't have managed switches installed. All other networking equipment I have monitored for years without such behaviour.
Strangely nslookup of 94.16.122.152 resolves s7.vonderste.in.
Not known as a part of the ntp.pool, maybe just an NTP client.
Indeed this doesnt explain the source ip.
Update:
Just now a new request was made from 192.168.90.100:123 to a different destination ip: 217.144.138.234, which appears to be an NTP server: ntp2.wup-de.hosts.301-moved.de. Again i am unable to locate the source ip / host on my LAN. Maybe some WireShark is in order...
