Bhikṣus! Mt. Meru’s northern side, halfway up from the earth, 42,000 yojanas tall, on the peak of Mt. Yugandhara are the three great cities of Vaiśravaṇa. What are their names? The first is called Viśāralabha (毘舍羅婆, Pí Shé Luó Pó); the second is called Gabhāvati (伽婆鉢帝, Jiā Pó Bō Dì); the third is called Aṭanaṭiya (阿荼槃多, Ā Tú Pá Duō).

From the Daśabhūmika Sūtra:
“O jinaputras! By analogy, the pure king of mountains Yugandhara, which is made of jewels, is an unceasing source of yaksas who have great miraculous powers, because of its multitudes of all yaksas who have great miraculous powers…
O jinaputras! By analogy, the pure king of mountains Aśvakarnagiri, which is made of jewels, is an unceasing source of all fruits because it possesses all fruits…
Notice above that we skip two mountains in between. Vaiśravaṇa rules over yakṣas of whom there are three species; these would fit the next three mountains. Now, based on Vaiśravaṇa being first, circumambulation goes clockwise and so the next Heavenly King is Dhṛtarāṣṭra whom rules over the Gandharvas; thus this circular mountain having abundant fruits makes sense.
O jinaputras! By analogy, the pure king of mountains Nimindhara, which is made out of jewels, is an unceasing source of all nagas who have great miraculous powers, because of its multitudes of all nāgas who have great miraculous powers…
Notice above that we skip the circular mountain Vinitaka, presumably if the first three are yakṣa domains and the last one was of the Gandharvas, then this must be of the Kumbhāṇḍas whom are ruled by Virūḍhaka. Now since Nimindhara has countless nāgas, this corresponds exactly to Virūpakṣa’s domain who rules over them.
O jinaputras! By analogy, the pure king of mountains Cakravada, which is made of jewels, is an unceasing source of all those who have powers, because of its multitudes of those who have powers…
Here would seem to be the rest of the dwellings of the powerful divine beings at the lowest level. Vaiśravaṇa ruling over the Rākṣasas in the north, Dhṛtarāṣṭra over the Piśācas in the east, Virūḍhaka over the Pretas in the south, and Virūpakṣan over the Pūtanas in the west.
O jinaputras! By analogy, the pure king of mountains Ketumat, which is made of jewels, is an unceasing source of all asuras who have great miraculous powers, because of its multitudes of asuras who have great miraculous powers.”
