4. Classe inetnum:

This document defines a transition path for publishing prefixlen URLs in inetnum: objects. Until RIRs and registrants have migrated to a native prefixlen: attribute, consumers MUST be able to consume both the remarks: and prefixlen: forms.

inetnum: 192.0.2.0/24 # example
remarks: Prefixlen https://example.com/prefixlen

inetnum: 192.0.2.0/24 # example
prefixlen: https://example.com/prefixlen

The token "Prefixlen" in the remarks: form MUST be case-sensitive. The URL MUST refer to a single prefixlen file. A prefixlen: attribute MUST be followed by a single URL that refers to a single prefixlen file. Consumers prioritize prefixlen: over remarks: if both are present. For inetnum: instances covering the same range, a signed prefixlen file MUST be preferred over an unsigned one; if none are signed or more than one is signed, the inetnum: with the most recent last-modified: attribute MUST be preferred. The most specific inetnum: object with a prefixlen reference MUST be used.
