While this is good, this should be an administrative control.

As an attacker this offers no real security though. 
Also, when the application is logging ip address in this manner other things tend to crop up. 
	.. Blind SQL, XSS ... 

Even though this may make an end user feel fuzzy care should be taken to avoid implementation errors for this especially when this is sighted when it isn't backed by the requirements doc within the application. 

Without this being in a requirements document and it exists within a finding this could easily prompt a developer to develop and not check this thus creating a greater attack surface. 

But in the end I would say weigh your options....
