# Object Identifier ## Identification AS7018 is AT&T's routing domain; IP geolocation is an inferred database mapping, not GPS. `OID` is an object identifier; `1.3.6.1.4.1` is the IANA private-enterprise branch; [[Abstract Syntax Notation One|ASN.1]] is a data-description notation; [[Structure of Management Information|SMI]] structures network-management objects. The geographic place names are hypotheses recorded during an investigation, not verified device locations. ## Notebook evidence - [[Scanned_20260730-1659#PDF page 34 — Network geolocation, AT&T ASN, OID, SMI, and IANA|PDF page 34: Network geolocation, AT&T ASN, OID, SMI, and IANA]] — This is a field investigation into why geolocation services disagreed. IP geolocation is probabilistic and commonly maps provider address space to registration, network, or inferred access locations rather than a precise device. AS7018 belongs to AT&T; the page tests San Antonio, Kenedy, Karnes County, Corpus Christi, and other hypotheses against two IPs. The OID arc `1.3.6.1.4.1` is the IANA Private Enterprise Number branch, used by organizations in SNMP/SMI and other ASN.1-based identifiers. ## Relationships and overlays The source places this record in an evidence cluster with [[Abstract Syntax Notation One|Abstract Syntax Notation One]] · [[AT&T|AT&T]] · [[Autonomous System Number|Autonomous System Number]] · [[Intel Corporation|Intel Corporation]] · [[Internet Assigned Numbers Authority|Internet Assigned Numbers Authority]] · [[IP Geolocation|IP Geolocation]] · [PERSON REDACTED] · [[Private Enterprise Number|Private Enterprise Number]] · [[Structure of Management Information|Structure of Management Information]]. The occurrence contributes to the notebook's larger model of [[Identity Continuity|identity continuity]], [[Device Sovereignty|device sovereignty]], and [[Continuity Architecture|continuity architecture]]. ## Evidentiary status and open leads Re-run the historical IP/WHOIS/geolocation comparison using archived data; identify the Nokia/geodetic references and “station FUEL.” ## Source - [[Scanned_20260730-1659|Scanned_20260730-1659]]
