How polluted is 1/8?

Hello,

After 1/8 was allocated to APNIC last week, the RIPE NCC did some
measurements to find out how "polluted" this block really is.

See some surprising results on RIPE Labs:
http://labs.ripe.net/content/pollution-18

Please also note the call for feedback at the bottom of the article.

Kind Regards,
Mirjam Kuehne

Not a suprise, unfortunately.

Re: How polluted is 1/8? [In reply to]

It should be of no surprise to anyone that a number of the remaining
prefixes are something of a mess(somebody ask t-mobile how they're using
14/8 internally for example). One's new ipv4 assignments are going to
be of significantly lower quality than the one received a decade ago,
The property is probably transitive in that the overall quality of the
ipv4 unicast space is declining...

The way to reduce the entropy in a system is to pump more energy in,
there's always the question however of whether that's even worth it or not.

Having this data is useful, but I can't help to think it would be
more useful if it were compared with 27/8, or other networks. Is
this slightly worse, or significantly worse than other networks?

I have only anecdotal information regarding 45/8.

45/8 is assigned to Interop, and as such it is brought up-and-down as
Interop's shows move in and out of convention centers. Starting at
least 5 years ago, it has proved impractical to start announcing 45/8,
since this causes immediate and massive amounts of traffic to flow into
the show network.

The last time that I know that the full 45/8 was announced, traffic
settled down to about a full T3's worth of bandwidth before the network
engineers started announcing smaller /16 chunks as actually needed.
Even /16 has proved impractical while the network is being built-out,
before the show, because the build-out site typically has T1-ish
bandwidth---again, saturated with a /16 being announced.

This information is very different from the RIPE Labs experiment which I
think showed that certain "obvious" addresses (1.1.1.1 seemed to be the
kicker in my short reading of their report) were being mis-used heavily.
But I suspect that 27/8 would have similar issues to 45/8.

However, it is not clear to me that this is different from any other /8.
In other words, for those that have a /8, they probably DO have to put
up with a T3-worth of garbage flowing their way before they move the
first useful packet. However, you don't get a /8 unless a T3 is small
potatoes to you, hence...

I would hope that the APNIC would opt not to assign networks that would
contain 1.1.1.1 or 1.2.3.4 to customers for exactly that reason. The
signal-to-noise ratio for those addresses is likely pretty high. The
noise is likely contained on many internal networks for now because a
corresponding route doesn't show up in the global routing table at the
moment. Once that changes....

I could see holding those prefixes aside for research purposes (spam
traps, honey pots, etc...).

I think it is too bad that we didn't have the forethought to route all
of those networks to 100-watt resistors some years ago.

When I last was admin of a small-corner of the world I routed a lot of
that kind of traffic (I don't remember it 1/? was part of that or not)
to the null interface.

If some unfortunate soul does get 1.1.1.1, 1.2.3.4, 1.3.3.7, etc, they
would also likely experience significant global reachability problems in
addition to all of the unintended noise that gets sent their way.

There are many sites that specifically filter those addresses, in
addition to those that don't update bogon filters, or assume "no one
will _ever_ get 1.2.3.4!" :)

They would make great DNS server IPs for someone who wanted to host them. :)

Just because I find it amusing timing... today I sat in a vendor presentation where he connected to his company's demo site and I smiled as I saw IP addresses in 45/8 (as well as 10/8 and others).

Yes, I did see that. What I noticed yesterday was that there were no
prefixes that cover 1.1.1.1 or 1.2.3.4 being announced globally at that
point.

The most surprising thing in that report was that someone has an AMS-IX
port at just 10 megs. It would be nice to see an actual measurement of
the traffic and daily/weekly changes. A breakdown of the flow data by
source ASN and source prefix (for the top 50-100 sources) would also be
interesting.

There was a call on the apnic list for someone to sink some of the traffic.

I'd like to see someone capture the data and post pcaps/netflow analysis, and possibly just run a http server on that /24 so people can test if their network is broken.

I've taken a peek at the traffic, and I don't think it's 100's of megs, but without a global view who knows.

I know someone who'd happily sink both the /24's in question.. if apnic's

Given that it is not in the table today, just announcing it would yield both interesting traffic, and interesting data on who is filtering it.

RE: How polluted is 1/8? [In reply to]

14/8 isn't all they are using internally.. 1,4,5,42 and that's just the
stuff that hasn't been delegated out by IANA yet.

I am sure this practice is pervasive.. and it's an issue that doesn't
typically come up in talks about prepping for IPv4 depletion. Maybe it
will now..

FWIW, I don't believe these netblocks are completely unusable. If RIR
policies permit you to get address space for private networks, it could
be allocated to an organization that understands and accepts the
pollution issue because they will never intend to route the space
publicly. (Such a thing does exist..)

If it's not obvious, I've thoguht about this and made some offers to the people at APNIC/RIPE.

Hoping someone moves forward with this.

The note was on the apops list (iirc).

Nor do I, people will receive assignments out of them, and route them
and cope with the occasional blackhole. Those whose applications or
internal numbering schemes use them will bear a not insignificant cost
associated with mitigation.

Re: How polluted is 1/8? [In reply to]

Hi Jared,

Merit would be happy to sink and collected this traffic. Perhaps even the entire /8
depending on the traffic level. Ideally we would want to do the entire /8.
We have disk and bandwidth in place for our other research activities and this would
fit in nicely. We could probably do a full pcap capture for a week or so and
make it publicly available to the broader research community.
