When I go to routers page in OpManager and want to add router for monitoring, I can add router by name or IP address. Than I can choose  netmask for IP address. But I can not choose netmask 255.255.255.255. Last netmask in the list is 255.255.255.252. Because of that I cannot choose loopback address as router IP(my loopback have netmask 255.255.255.255). I want to know what is the reason for that situation, will choosing netmask 255.255.255.255 be posibility in some future OpManager versions?

Thanks in advance!
