That IP address is what a DNS lookup returns, so it depends on your dns 
server and domain search list (as configured on the backuppc server).  I 
thought it would use nmblookup if you checked the dhcp box in the 
backuppc hosts config.  If it is a static IP, you can use the 
ClientAlias setting to supply the IP if DNS doesn't work.
