What does
    getent hosts
return on your system?  That's where _hosts gets the list of hosts.

Only if getent isn't present does it look directly at /etc/hosts,
and also at "ypcat hosts" if there is ypcat.

If getent isn't returning anything useful, you can replace it:

zstyle ':completion:*:hosts' command 'cat /etc/hosts'

Or explicitly list all the hosts yourself:

zstyle ':completion:*:hosts' hosts $(awk '/^[^#]/ {print $2}' /etc/hosts)

Note there have been several other fixes/improvements to ssh host-gathering
since zsh 5.0.
