How this entity was disambiguated
This entity first appeared as the object of triple T13551718 — 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: Requirements for IP Version 4 Routers Context triple: [RFC 1812, title, Requirements for IP Version 4 Routers]
-
A.
Classless Inter-Domain Routing
Classless Inter-Domain Routing (CIDR) is an IP addressing and routing scheme that replaces traditional class-based networks to enable more efficient allocation of IP address space and improved route aggregation on the internet.
-
B.
IP/ICMP Translation Algorithm
IP/ICMP Translation Algorithm is an IETF-specified mechanism that enables interoperability between IPv4 and IPv6 networks by translating IP and ICMP headers and messages between the two protocol versions.
-
C.
Internet Protocol fragmentation and reassembly
Internet Protocol fragmentation and reassembly is the process by which large IP packets are split into smaller fragments for transmission across networks with limited maximum transmission units and then reassembled back into the original packet at the destination.
-
D.
Requirements for Internet Hosts – Communication Layers
"Requirements for Internet Hosts – Communication Layers" is an IETF standards document (RFC 1122) that specifies the protocol and behavior requirements for Internet host communication across the network, transport, and related layers.
-
E.
RFC 2451
RFC 2451 is an Internet Engineering Task Force (IETF) standard that specifies how to use the Twofish encryption algorithm within the IPsec protocol suite for secure network communications.
- 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: Requirements for IP Version 4 Routers Description of subject: Requirements for IP Version 4 Routers is an IETF standards-track document (RFC 1812) that specifies the functional and protocol requirements that IPv4 routers must follow to ensure interoperability on the Internet.
