# Éric Vyncke, INT AD, comments for draft-ietf-dnsop-dns-catalog-zones-08
CC @evyncke

Thank you for the work put into this document. I really like the ideas behind
this IETF draft (OTOH, DNS is now used as a control/transport protocol pretty
much BGP nowadays...). But, I second Murray's DISCUSS point about IANA (and his
ask to get an example because the whole document is not really easy to read for
a non expert).

Please find below some non-blocking COMMENT points (but replies would be
appreciated even if only for my own education), and some nits.

Special thanks to Tim Wicinski for the shepherd's write-up including the WG
consensus *but* lacking the justification of the intended status :-(

I hope that this review helps to improve the document,

Regards,

-éric

## COMMENTS

### Lack of revised I-D after IETF Last Call

David Black did a Last Call review for the DNS directorate on the 27th of
December 2022:
https://mailarchive.ietf.org/arch/msg/dnsdir/7v58S0wA1G5KfiwTrrEdYAqT73w/

Probably due to some personal time during that week, no replies/text changes
are done yet. Are the authors intending to reply to David ?

### Section 1

Should IXFR / AXFR be cited with a reference ? Even if they are part of the RFC
Editor set of known abbreviations.

### Section 4.1

Isn't the SOA serial already specified as being increased as soon as the zone
content is changed ? If so, why repeating the MUST here ?

### Section 4.2

Even if the TTL value is to be ignored by secondary servers, is there a
recommended value to be used in the catalog zone ?

### Section 4.3.1

Suggest removing "For this memo, ".

### Section 4

Should there be a clear indication about which label to use for each property?
I.e., `the "coo" label is used for the change of ownership property`.

Should there be a IANA registry for all those special labels / property ? Or
would it be an overkill ?

### Section 4.4.1

Just 2 personal comments, no need to reply... But,

* re-using the same node label among zones may be complex, I would have
specified all zone properties are reset after a migration to start from a clean
state * I am unsure whether the last paragraph procedure is reliable and easy
to do.

### Section 4.4.2.1

s/between the producer and the consumer of the catalog/between the producer and
the consumer(s) of the catalog/ ?

### Section 6

Mostly at a DISCUSS level, but about the 1st paragraph, the 2 sentences are
contradictory (as "invalid." is not under control of the catalog producer):

* `a catalog producer MUST NOT use names that are not under the control of the
catalog producer` * `It is RECOMMENDED ...or to use a name under a suitable
name such as "invalid."`

## NITS

### I.e.

s/i.e./i.e.,/

### Section 3

s/Its records/Its resource records/ ? and introduce the RR abbreviation ?

s/for such zones/for regular zones/ ?

### Section 6

s/when catalog zones or another automatic configuration mechanism is not in
place/when catalog zones or another automatic configuration mechanism are not
in place/ ?
