ip classless

Hi All,
I want to know what does "no ip classless" mean?Is it ip subnet -zero or no ip-subnet zero?
thanks

Webmaster

If you use no ip classless, a packet destined for 10.0.0.0 /255.255.0.0 will not be forwarded using the route for network 10.0.0.0 /255.0.0.0...

At times the router might receive packets destined for a subnet of a network that has no network default route. To have the Cisco IOS software forward such packets to the best supernet route possible, use the ip classless global configuration command. To disable this feature, use the no form of this command.
