You may also want to include the FQDN and any other aliases for each 
machine.  Otherwise if you try to ssh to a host using an FQDN or 
alias/CNAME, ssh will add a new entry to ~/.ssh/known_hosts with the 
new name, even if an entry for that IP address already exists in the 
global /etc/ssh/ssh_known_hosts.
