IP bans?

Something that’s been on the back burner of my mind recently is the upcoming reality that my little brother is going to start using discord since he will be 13 soon. I’m generally worried that he will do something that will get him banned whether it be because of something he does or discord doing the “if we ban x server then we ban everyone in it.” Is discord known to do IP bans? Cause my father and myself have discord accounts on the same internet.

Sorry if the wording is weird I’m pretty tired rn writing this.
