DNS

DNS, DNSSEC, encrypted DNS transports, and AS112. The RFCs whose summary names the dns aggregate, with their mandatory and optional coverage.

Mandatory11.4%34 of 299 (11.4%)

MUST, MUST NOT, REQUIRED, SHALL and SHALL NOT rows of the walked RFCs that a recorded test break proves.

Optional0.5%1 of 211 (0.5%)

MAY, NOT RECOMMENDED, OPTIONAL, RECOMMENDED, SHOULD and SHOULD NOT rows, counted the same way.

Mandatory ceiling49.8%149 of 299 (49.8%); excluded: Optional feature not offered (classification can be revisited): 1 of 299 (0.3%); Not applicable (classification can be revisited): 149 of 299 (49.8%)

Attainable mandatory rows under current classifications, over the unchanged total.

Optional ceiling100.0%211 of 211 (100.0%)

Attainable optional rows under current classifications, over the unchanged total.

Not walked0of 11 RFCs

RFCs with no valid extraction sign-off: their rows count in neither figure.

Mandatory registernot completeevery row proven, none unwalked

A profile is complete only when it requires at least one RFC and none of them is unwalked.

Mandatory ceiling: 149 of 299 (49.8%); excluded: Optional feature not offered (classification can be revisited): 1 of 299 (0.3%); Not applicable (classification can be revisited): 149 of 299 (49.8%). Optional ceiling: 211 of 211 (100.0%). Lowest mandatory ceiling: rfc2782 0 of 7 (0.0%). Lowest optional ceiling: rfc1035 6 of 6 (100.0%). Ceilings describe current classifications, not an immutable Linux maximum. Not-applicable and feature-declined classifications can be revisited. Every gap remains work Ze owes.

Tree

Roots first: an RFC sits one level above the highest level of the RFCs it builds on, and the RFCs of one citation cycle share a level. Each bar is the share of that figure's rows a recorded break proves; the ceiling below it shows attainable rows under current classifications. An RFC that is not walked shows an empty bar and no figure or ceiling.
