weird connections in Wi-Fi inspector

i am getting 3 weird connections under the wifi connections displaying in the avast wifi inspector, their ip address looks like a mac address and they dont show up on my router and all 3 have the same mac address. I have attached all needed logs and a screenshot of the 3 connections.

Can it be phone / TV / printer … ?

the only phone connected to the router already shows up in the inspector and no printer, ive just woken up and turned on my pc on there is now only 1 of these connections with a different mac address. These connections also dont show up on anyone elses PC in the wifi inspector only mine.

edit: just did another network scan and am back up to 3 of these weird connections.

Your PC is clean. On screenshot are shown IPv6 link-local addresses of devices in your network generated using EUI-64. One of them is router link-local address

The following will implement some post-cleanup procedures:

Click Run button and wait a few seconds for the programme completes his work.
At this point all the tools we used here should be gone. Tool will create an report for you (C:[b]DelFix.txt[/b])

The tool will also record healthy state of registry and make a backup using ERUNT program in %windir%\ERUNT\DelFix
Tool deletes old system restore points and create a fresh system restore point after cleaning.

thanks. thing is non of our computers use IPv6 and is even disabled on my router

Even if they don’t have global unicast IPv6 address configured, link-local IPv6 address is assigned automatically on all devices including PCs and smartphones.
