Wasn't there an RFC written about this by some australian bloke? I'd say
that whoever maintains the CIDR report these days should really take a
couple of minutes to clue themselves in about asplain syntax.

Re: The Cidr Report - 4byte ASN handling [ In reply to ]
Strangely, both the RFC (5396) and the CIDR report appear to be written by the same
guy...Geoff.

btw, am i the only one who finds it easier to remember asdot formatted ASNs?

Indeed.

I suppose it will be interesting to see how the vendors
respond to this. Would they retract support for as-dot, as
it's been shipping for a while now?

Cheers,

Mark.

They're easier to remember, but if you operate an ASN for a
reasonable period of time, it's okay to assume that you will
remember it, whether it's as-plain or otherwise.

The same would hold true for your favorite upstreams, peers,
customers and role model ISP's :-).

Cheers,

Mark.
Re: The Cidr Report - 4byte ASN handling [ In reply to ]
I say we all start using octal two's complement for extended ASNs.

(note to self: don't post to NANOG after a night out with a vendor.)

From what I learned at the latest NANOG it's very clear that nobody reads this any more.

Is there any good reason to persist in spamming the nanog list with this report?

some read it. we are the frustrated ones.

no one seems to act on it.

not clear, sad to say.

i really think that the only way to reduce fragging is filtering. maybe
a bgp blackhole feed for frags for which there are covering prefixes?

Some read it. I think everyone on NANOG is frustrated (or not paying attention).

I would suggest that you keep sending it, but I have no way to motivate you to do so other than to confirm I do read it.


> no one seems to act on it.

It is useful even just as data to show others, whether they act on that data or not.

If history is any guide, this will not work. Someone will listen, and those who do not will lose customer (i.e. money).

The Internet is a business, and therefore money talks. To date, no one has been able to prove to the bean counters that more prefixes means less profit.

For instance, I spoke to someone at the conference whose company is spewing 1000s of prefixes they do not have to. That person said "well, FIB compression makes everything OK, so it doesn't matter, right?" (paraphrased). This is a company who tells others "you have to pay me to use my resources", yet feels absolutely no qualms about using other networks' resources for free.

Hypocrisy is live & well on the Internet. (I know you are all shocked.)

I do; I check the weekly increase every week, and check who the top
offenders are. If someone from my vicinity/circles is on the list
(doesn't happen frequently; more often for the BGP updates report than
for CIDR), I may send them a note and ask what happened.

"Reads" may be an exaggeration, but I'm sure some look at it.

> Is there any good reason to persist in spamming the nanog list with

I think it still provides an incentive for people not to mess things up
too badly; and a chance of some mishaps to be noticed quicker, with a
little help from your friends.

the email i want to see here is "i wuz a polluter, but i read the cidr
report, i haz seen the light, and i'm gonna stop polluting."

no, i am not holding my breath.

I do. While most of the content of the actual mail has very little
relevance to me, it does provide useful leverage and motivation to fix
some of the networks where I do have influence.

> From what I learned at the latest NANOG it's very clear that nobody reads this any more.

I often don't have the time to read every report in detail and much of
it applies to networks outside of my circles. Every few weeks it does
however prompt me to go and review my own network (and sometimes wave a
stick at few ops people)

> Is there any good reason to persist in spamming the nanog list with this report?

I definitely think its still useful for the community. Perhaps the
frequency could be dialed back a little? I'm sure that there are many
people who don't really notice it any more due to their mental white
noise filters.

Perhaps some slightly different presentations of the data would also
make it more useful. I am quite interested in the number of prefixes of
various lengths that are seen in the table and that doesn't get included
in the mailed report.

Perhaps a "biggest climbers & fallers" list would also have more
relevance for the regular report. The "Top 30" list doesn't seem to
change very often... ;-)

Yes, and if only to tell people that we could do a lot better if we'd care more
about the Net than .. (?)economics(?) ..?

I keep wondering if people generate more elaborated filters based on the overall
data to get down table sizes rather than saying >=/24 only or similar?

To me it reads as we'd still be below 256k then rather than close to 400k? Or more
realistically 300k-ish? Anyone done any research how that would affect various
numbers in forwarding paths? *hide*


> From what I learned at the latest NANOG it's very clear that nobody reads this any more.

Read? Or act?

Where are the BNOsFH these days?


> Is there any good reason to persist in spamming the nanog list with this report?

A good reason would be to add the same damned thing for IPv6 as well to avoid
us starting with the same *beep* there already. There was a great number of
noise in the table when I last looked myself (given it's been a longer while).

Now we want to encourage people to deploy IPv6 and not make it harder for them
but a lot of obstacles in policies from the very early days are gone these days
and could be cleaned up before it's too late and in addition if people roll it
out now, why not do it once and do it right from the beginning, but where's the
education on `eek not the same *beep* as with legacy IP again`, as some people
are trapped in BBCP (bad best current practices)?

Well I know you have it online, but polling a website is harder than getting
it delivered to the inbox every week;)

Re: The Cidr Report [ In reply to ]
Randy,
yes, our ASN landed on polluter list once and we fixed it. I think there is
nothing wrong in sharing that.

Me and few bunch of self acclaimed geeks of our region read it and have done
our level best to remove few polluters but with very less success. Seems
like those who should be reading it are either too busy polluting or using
hushmail.

Geof, this is very useful stuff for many. so how many uniqe hits you get on
the website?
