Bagaimana cara menghapus data CNAME?

Saya menggunakan nama host basic.localmachine.io untuk pengembangan lokal dan menunjuk ke localhost. Untuk beberapa alasan, basic.localmachine.io memiliki set CNAME di mesin saya ke basic.wpengine.com. Saya tidak tahu bagaimana itu terjadi, dan saya ingin menghapusnya.

gali output untuk basic.localmachine.io
