I am pretty new to the whole "setup your own router that can do pretty much everything". Whilst configuring I stumbled upon some (for me) weird settings: I can set hostnames via (1) "Network" -> "Hostnames" and via static IPs under (2) " DHCP and DNS" -> "Static Leases".
For me there seems not to be any difference if I enter something in (1) when having configured static IPs (my machines are reachable via their names configured in (2)). So what is the difference? When do I need to choose what option? I could not find any information in the wiki looking for "hostname". I am pretty solid in Linux and stuff but networking is a topic I did never wet my feet with so please explain to me like I am 5.
