IK Solver Constraint

The Inverse Kinematics constraint implements the inverse kinematics armature posing technique. Hence, it is only available for bones. To quickly create an IK constraint with a target, select a bone in pose mode, and press ⇧ Shift I.

This constraint is fully documented in the inverse kinematics page of the rigging chapter.
