How this entity was disambiguated
This entity first appeared as the object of triple T187730 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: OSPFv3 Context triple: [Internet Protocol version 6, supportsRoutingProtocol, OSPFv3]
-
A.
Internet Protocol version 6
Internet Protocol version 6 (IPv6) is the modern Internet addressing and routing protocol designed to replace IPv4 by providing a vastly larger address space and improved network efficiency and security features.
-
B.
IEEE 802.1Q VLAN tagging standard
The IEEE 802.1Q VLAN tagging standard defines how virtual LANs are implemented and identified over Ethernet networks by inserting a VLAN tag into Ethernet frames.
-
C.
RFC 791
RFC 791 is the foundational Internet standard that specifies the design, structure, and operation of the Internet Protocol version 4 (IPv4).
-
D.
IEEE 802.21
IEEE 802.21 is a standard that defines mechanisms to enable seamless handover and interoperability between heterogeneous network types, such as Wi-Fi, cellular, and Ethernet.
-
E.
IPv4
IPv4 is the fourth version of the Internet Protocol, providing a 32-bit address space that underpins most of today’s internet routing and communication.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: OSPFv3 Description of subject: OSPFv3 is the version of the Open Shortest Path First routing protocol designed to operate over IPv6 networks, providing link-state routing and support for IPv6 addressing and features.
