D.C. Code § 47-1375
At the time the summons (or initial summons) is issued, the plaintiff shall obtain an order of publication directed to all defendants, naming them as provided by this chapter. The real property shall be described in the order of publication as the real property is described on the certificate of sale along with the street address, if any. The order of publication shall notify all persons that have, or claim to have, an interest in the real property to answer the complaint or to redeem the real property on or before the date named in the order of publication and, in case of failure to appear, answer, or redeem the real property, that a judgment will be entered that forecloses the right of redemption in the real property. The date named may not be less than 60 days from the date of the order. Subject to § 47-1371(b), when the order of publication is issued and published, any person that has any right, title, interest, claim, lien, or equity of redemption in the real property is bound by the judgment of the court that may be entered in the case as if the person were personally served with process. The order of publication shall be in substantially the following form:
