[arch-general] Network configuration

Dear list,
I have a router which automatically identifies the devices connected to 
it by their host name (its a FritzBox if that matters). However, this 
does not work for all my arch-boxes. Thus, I get the feeling, I am 
missing something in my network configuration.

Usually, I edit /etc/hostname by putting just the hostname in there. 
There is also the tool
    hostnamectl set-hostname myhostname
which does the same. The arch wiki says, that the file also may contain 
the domain, if any. How do I set a hostname with domain? Is it just
    hostnamectl set-hostname myhostname.domain

Then, the arch wiki says, that it is a good idea to add the hostname as 
alias for localhost in /etc/hosts. Do you do that?

And last, which piece of information determines the computers name in 
the network. Is it the hostname in /etc/hostname, or more likely the 
aliases in /etc/hosts? Is there anything more I should configure?
