Spencer Sevilla spencer.builds.networks at gmail.comTo add-on to this discussion, I do not believe that the subnet " 55.55.0.25/16" is valid. The entire point of the netmask (in this case 16) is to denote the length of the network address in bits. A bitwise AND operation should always provide the routing prefix, in this case 55.55.0.0. A subnet with a non-zero value is only possible on orders of 2 and with an appropriately long netmask, e.g. 55.55.0.128/25.
