The group-order style takes just group names as values, no fancy
aliasing or description stuff, that comes with the tag-order style.
Like so:

  zstyle ':completion:*:ssh:*' tag-order \
    'hosts:-domain:domains hosts:-ipaddr:IP\ addresses *'
  zstyle ':completion:*:ssh:*' group-order \
    hosts-domain users hosts-ipaddr
  zstyle ':completion:*:ssh:*:hosts-domain' ignored-patterns '<->.<->.<->.<->'
  zstyle ':completion:*:ssh:*:hosts-ipaddr' ignored-patterns '^<->.<->.<->.<->'
  zstyle -e ':completion:*:ssh:*' hosts 'reply=(
    ${=${${(f)"$(cat {/etc/ssh_,~/.ssh/known_}hosts(|2)(N) \
		     /dev/null)"}%%[# ]*}//,/ }
    ${=${(f)"$(cat /etc/hosts(|)(N) <<(ypcat hosts 2>/dev/null))"}%%\#*}
    )'

Which gives me what you want.
