host="18.104.22.168"... in ~/.ssh/authorized_keys2
The older versions SSH-1.2X allowed for the practical AllowHosts directive in /etc/ssh/sshd_config, they are compiled it with TCP Wrappers (libwrap) so you should be able to use /etc/hosts.(deny,allow).
Now if you suspect it isnt set up with wrappers just compile your own --with-tcp-wrappers.
You can also add allowed IP's to iptables/ipchains for that extra edge :-].
What I do is add a file with a single IP per line, then add a bi-directional rule in the script, like:
for host in $(/bin/cat /etc/hosts.ssh); do $host; done
Keeps the script clean, and all allowed IP's easily accessable.
