in addition you can actually limit access to the sshd with the keywords
AllowUsers and AllowGroups with the corresponding user/group _names_
(not uid/gid!!!).

But there's no option to do this ip-based (this is possible with
packetfilters or tcp-wrapper).

Do a "netstat -na|grep LISTEN|grep 22" to prove on which IP your
ssh-Server is listening.
