How this entity was disambiguated
This entity first appeared as the object of triple T1077175 — 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.

Entity disambiguation (via context triple)
gpt-5-mini-2025-08-07
Target entity: DNS64 Context triple: [NAT64, oftenUsedWith, DNS64]
-
A.
NAT64
NAT64 is a network address translation mechanism that enables IPv6-only clients to communicate with IPv4 servers by translating between the two protocol address spaces and packet formats.
-
B.
Teredo
Teredo is a tunneling protocol that enables IPv6 connectivity for devices on IPv4 networks, particularly those behind NAT.
-
C.
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.
-
D.
DNS over QUIC (DoQ)
DNS over QUIC (DoQ) is a modern DNS transport protocol that uses the QUIC encrypted, multiplexed UDP-based transport to provide faster, more secure, and more reliable DNS queries than traditional methods.
-
E.
BGP-4+
BGP-4+ is an enhanced version of the Border Gateway Protocol designed to support routing for IPv6 networks.
- 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: DNS64 Description of subject: DNS64 is a network mechanism that synthesizes IPv6 addresses from IPv4 DNS records to enable IPv6-only clients to reach IPv4-only servers, typically used together with NAT64.
