[DBWG] stale route6 and domain objects for removed inet6num

Dear James,

Thanks for your email.

I want to respond as an AfriNIC member, *not* as DBWG co-chair.
Also, I'm known to be sometimes a bit too blunt, and i'm currently not
sure if i can avoid this here. Apologies in advance.

We (non-staff outsiders) probably don't need to know all the internals,
but in this case i think it would comfort me if we had some indication
that internal details are being looked at (critically) and this and more
bug(s) get fixed. with intention of pro-activeness.
We don't know whether the 'mechanisms that checks for child objects' is
a script for a human to follow and a passage should be more highlighted,
or whether that's a script for a machine where a '6?' is missing in a
regular expression right after 'route' .

And we shouldn't be involved in this. I just want to express that it
would be very comforting if we could get to see - by results, of course
- that this is taken seriously and being looked at.

Maybe there should or could be some incentives to find issues. and to
fix them. Anything i can think of can probably be "gamed", and i
shouldn't get into details.
[I included Arthur for that. he had asked me ages ago for feedback, took
me long to give some;-)]

So I wanted also to mention:
If I found an embarrassing bug or mistake in my database, I would really
try hard to fix it, if not before sending the response email, then at
least immediately after.

If not done 2.5 hours after the email is sent, a troublesome outsider
(named Frank) could already think the issue gets neglected or forgotten.

the route6 object is still there:
$ whois -h whois.afrinic.net -- -T route6 2c0f:f370::/32 | egrep -A 4
'^rout'
route6: 2c0f:f370::/32
descr: Auvionics-v6
origin: AS328097
mnt-by: AA96-MNT
source: AFRINIC # Filtered

Since the bug existed when the inet6num was deleted, the route6 wasn't
deleted during inet6num deletion, I would believe that manual
intervention is required.

And it seems to me that it still wasn't done.

I simply don't want to do the same check for the domain object for the
same prefix - I leave that to staff. [maybe I can ask Arthur to drop me
a note when both are removed]


Now about an idea for a way forward:
[and I hope that's obvious, but i request forgiveness that I don't want
to assume too much]
Someone could volunteer to find additional objects that were orphaned
through the same process as the objects in this case i discovered.

- go through all existing domain objects ending in 'ip6.arpa' and see if
the covering (or equal) inet6num objects exist -
and are *not* equal to ("2c00::/12" or "2001:4200::/23")
- go through all existing route6 objects, and do the same test.

I strongly believe that we shouldn't look for a volunteer from the
community for this - AfriNIC staff is just much better equipped (and
paid) to do that.


Finally I want to mention a word about impact.

[we can't thank Job enough for some of the great tools he's
contributing, nevertheless: Thank you, Job Snijders!!!]

http://irrexplorer.nlnog.net/search/328097
currently shows 3 AS-SETs in RIPE and one AS-SET in AfriNIC that include
AS328097, which means that real operators are putting 2c0f:f370::/32
into real filters, eating up resources ...
<sarcasm>...and leading to earlier upgrade requirements, spending money
that we all would rather spend on AfriNIC fees...... </sarcasm>

Now I'm co-guilty; and I will fix 2 of these AS-SETs within 15 minutes
after sending this email, and make an email to someone to fix the 3rd
within 30 minutes....

So maybe http://irrexplorer.nlnog.net/search/328097 will already look
better by the time you guys check.

Thanks,
Frank
