Why ip is called connectionless?

Answer 1

IP is connectionless because you don't want routing to reply to every routing request; it would slow things down to almost a stop. The router has to assume that the packet arrives where it was sent.

Answer 2

Individual IP packets are sent, without establishing a connection, and without verifying whether each IP packet reached its destination. If needed, those functions are taken care of at a higher level, usually layer 4 (TCP).

Answer 3

IP is connectionless because it would slow down networks if every packet that was routed needed to have an acknowledgment. It would also cause severe bottlenecks, and the routing piece doesn't need guaranteed delivery. If reliable delivery is necessary, then the transport layer will take care of that.
