Probably you need to assign this ip on loopback interface. 
This address will no more used for arp, but still can be accessible if
there is route (IPv4 gw based or LLaddr gw based) for other hosts on
ethernet.

But, there is some drawbacks also - source IP address autoselect will
not chose this IP when you connection to other host.
