If what you want is only to permit access to 4 host addresses then this access list should do it:

access-list 101 permit ip any host n.n.n.n

access-list 101 permit ip any host x.x.x.x

access-list 101 permit ip any host y.y.y.y

access-list 101 permit ip any host z.z.z.z

and on the interface:

ip access-group 101 in

where n.n.n.n, x.x.x.x, y.y.y.y, and z.z.z.z are the 4 IP addresses to which you want to give access.

I am slightly concerned that there may be things like routing updates, remote management, or other functions that may be impacted by this. But it does what you asked and permits access only to the 4 addresses. If it is too restrictive then re-statement of the requirements would be needed.
