No, it should be a /29.  The first address is the network address,  
and the last is the broadcast address and one should be assigned for  
the gateway, that is why they only allow for 5 static IPs.  Your  
netmask should be 255.255.255.248 if they set it up properly.  This  
is standard.  An example would be 192.168.1.0/29 where 192.168.1.0 is  
the network address, 192.168.1.7 is the broadcast address and one of  
the IPs would be assigned by the network admin as the gateway,  
normally .1 or .6 (either end), but any IP could be used.  This  
leaves the other 5 for general usage.
