I believe Iron Dome is designed to deal with what would be traditionally termed short range weapons like mortars and light-rockets. These weapons are light weight, can be fabricated in comparatively primitive conditions and can be deployed by irregular forces.

The conventional weapons that North Korea could use against Seoul are from the other end of the spectrum. Nearly all of them are patterned after Soviet versions which were designed to fit in a doctrine that favored the deployment and use of large numbers of heavy tube and rocket artillery. North Korea possesses large numbers of 153mm and 170mm guns and 240mm multiple unguided rocket launchers. Many of these are in fortified positions that are within range of Seoul.
