I say, and with God's success: Wiping the neck in ablution is among the recommended acts, and there are numerous evidences supporting this issue, which Al-Laknawi elaborated on in "Tuhfat al-Talabah" regarding wiping the neck. Among them is the narration from Talhah ibn Masrif from his father from his grandfather, may Allah be pleased with him: "I saw the Messenger of Allah, peace be upon him, wipe his head once until he reached the nape of the neck," and the nape is the area at the back of the head, as mentioned in "Al-Misbah Al-Munir" 2: 495. In another narration: "the beginning of the nape" in "Musnad Ahmad" 3: 481, "Sunan Abi Dawood" 1: 32, and "Sharh Ma'ani Al-Athar" 1: 30, and Allah knows best.
