Hi Linbo, I assume you mean on the loopback adapter? If so then use a 255.255.255.255 or /32 for safety, not all OS's may need it as there can be many ways to make it not respond to ARP, however, this also helps as you are telling the OS it's a single address.
Or do you mean the "netmask" in the ldirectord config which affects persistence? When this is at the default of 255.255.255.255 persistence will work per source address so 192.168.0.10 and 192.168.0.11 would get stuck to different servers. If you set 255.255.255.0 then they would both hit the same server as persistence would work by subnet so the whole 192.168.0.0/24 subnet would be stuck to the first server. Hope that's relevant to your question and makes sense...
