A DTN Node ID is an identifier used in the Bundle Protocol\r\n(BP) to name a \"singleton endpoint\": an endpoint that is registered\r\non a single BP Node. The DTN Node ID is encoded both as a certificate\r\nSubject Alternative Name (SAN) identity of type otherName with an\r\nOther Name form of BundleEID and as an ACME Identifier type \"bundleEID\".","pub_date":"November 2025","keywords":["ACME","DTN"],"obsoletes":[],"obsoleted_by":[],"updates":[],"updated_by":[],"see_also":[],"doi":"10.17487\/RFC9891","errata_url":null}
