Router client with IP of and no MAC address. What the heck?

Surf SOHO MK3 running firmware 7.1.2.

On June 13, 2020 the Daily Bandwidth report showed a LAN client with an IP address of and a blank MAC address. Screen shot below.

Looking at the Monthly Bandwidth report for May 2020, same thing, as shown below.

Any guesses what this is? calls it a bogon. refers to RFC6598.

Is it just me? Anyone else see this in their Monthly Bandwidth report?

OK will do.
FYI: I created an outbound firewall rule to log any traffic from this IP address. We’ll see if it catches anything …

Do you have Chromebooks with Android apps on your network?

Yes there are Chromebooks with Android apps. Why do you ask?

That’s what’s causing those IP addresses and MAC address to show up.


Well well well. Interesting. Thanks.

I just tested a Chromebook with Android apps and the unusual IP address did not appear anywhere in the router. That doesn’t make the earlier observations wrong. It could be that it only happens sometimes. Or that ChromeOS has changed over time.
