   Dear Fedi, I have another #Linux question.

   I've noticed some time ago that most of my Linux devices have two IP addresses in my local network, on a single wlan interface (192.168.1.127 and 192.168.1.128 in this screenshot)

   Both of them work - I can ping those addresses from another device in a local network.

   Why is that so? Why two addresses for one network interface? And how?

     @gulli I do have docker set up. But both adressess appear on the wlan interface. Can docker containers influence a physical interface configuration?

     @kuba maybe some docker containers running?

     @kuba
     Looks like an alias has been assigned. Normally that only happens if you make a static configuration. Maybe double configured or typo in network mask? Does the issue remain after a reboot?

     @mboelen yes, it's persistent across reboots
