The thought process is the same as the guide you are reading. https://www.oreilly.com/library/view/kerberos-the-definitive/0596004036/ch04s03.html
It says in the last paragraph on this page that the /etc/hosts file should have the '127.0.0.1 localhost <not-FQDN>' (last part is definitely optional) and then that the next entry should have the outer IP address mapped to the FQDN.
