The vast majority of attacks on Tehran and Karaj were carried out from the direction of the Caspia Sea, after crossing through Azerbaijan. The attacks on Tabriz and surroundings were carried out by entering Iran through northern Iraq. The attacks on Khorammabad and Kermanshah were carried out largely from Iraqi territory due to their proximity to the border.
Lastly, the attacks on Esfahan, Natanz, Arak and surrounding areas were carried out by entering Iran through a weakened air defense corridor. We know the jets were close to Esfahan (therefore inside Iran) because they used short-range Spice-1000 bombs.
