hostname_aliases: []

A list of any other hostname aliases you may want to assign this host.

hostname_othernames: []

A dict for setting up additional /etc/hosts entries. Each entry in the dict has an address element for the IP address and a hostnames element, which can be either a single string or a list of strings, representing one or more hostnames you want associated with that IP.
