samba - Mar 2009 - Is this subnet stated correctly?

Hi All,

When I reset smb (/etc/rc.d/init.d/smb restart), I notice
the following im my /var/log/messages

         Mar 29 19:35:34 foo nmbd[11286]:   Samba name
         server SERVER is now a local master browser for
         workgroup FOO on subnet 192.168.255.10

Should not it be stated as "192.168.255.0/24" instead
of "192.168.255.10"?  ".10" is a direct IP, not a subnet.
Am I missing something here?

Many thanks,
-T
