By looking at these logs would someone tell me if a predator is trying to hack my network especially where it reads something is being solicited.

My IPV6 address is 2600:1700:1fb0:a7b0:: why is a different address of 2600:1700:1fb0:a7b0:: being deleted from pool. Is this someone else IP address?

Also, I know nothing about creating a script to prevent anyone or no one from sniffing my network. I'm using MacOS - bash/terminal. Could someone give me a script to prevent my network from being sniffed. Again I'm using macOS and not windows

Thank You

First, no we can't tell you anything based on what you posted. Secondly, we aren't going to give/write you a script; YOU have to show effort of your own; read the "Question Guidelines" link in my posting signature.

And you're posting on LinuxQuestions...asking about a Mac, running MacOS. MacOS is not Linux...you need to ask on a Mac forum.
