network

Hello
Control panel>network and internet>view network computer and devices>router>properties>general>settings>
Here it says select the ones internet users can connect to;
I do not want to compromise security but what type of items should be here?
I have two with the same name but different endings and a third I know nothing about. All are selected and I am asking if any should be here or if they are is it because I use them to communicate on the web?
Thank you for your help
