What causes this? I didn’t have the problem in 2.9.51 Upgrade to V3 it does it back to 2.9 it goes away.

00:1E:79:21:72:51 is IP of what? maybe some device in proxy-arp mode?
Got it. It is my upstream provider’s router. Just got to see what the deal is there now.
The upstream provider uses a Cisco router which matches the Mac address listed. They do have proxy-arp enabled and refuse to turn it off.
How can I correct this on my end?
hmmm… why do you need to correct it?
It renders IP scan useless unless I specify the interface and the router has many many interfaces…
