If they don't do that, then you are stuck with more ad-hoc methods like

private ip addresses from ISP

2006-05-17 Thread adrian kok

Hi all

Have you had this experience?

Our router is running BGP and connecting to our
upstream provider with /30 network.   Our log reveals
that there are private IP addresses reaching our
router's interface that is facing our upstream ISP. 
How could this be possible?  Should upstream ISP be
blocking private IP address according to standard
configuration?  Could the packet be stripped and IP be
converted somehow during the transition? It happens in
many Tier-1 ISP though !

Thank you for your information


RE: private ip addresses from ISP

2006-05-17 Thread Ivan Groenewald

What do you mean by reaching?

Two quick observations from a mis-configuration point of view:
If you mean you are seeing BGP routes for those networks: Sometimes ISPs
null route private addresses with static routes in their networks and they
accidentally leak (redistribute) to customers/peers. There are obviously
other reasons too, but you can filter stuff like that yourself. Just don't
accept routes for private IP space from you upstream.

If you mean you are getting traffic destined for RFC1918 space, then make
sure you aren't announcing those networks to your upstreams by accident.
Poor upstream configs/filters could allow stuff like that to escape to peers
of the upstream. (stranger things have happened)

It's not normal or necessary to see those routes or traffic. Just contact
your upstream and point it out they should fix it.

RIPE IP Anti-Spoofing Task Force 
== 

IP source address spoofing is the practice of originating IP datagrams 
with source addresses other than those assigned to the host of origin. 
In simple words the host pretends to be some other host. 

This can be exploited in various ways, most notably to execute DoS 
amplification attacks which cause an amplifier host to send traffic to 
the spoofed address. 

There are many recommendations to prevent IP spoofing by ingress 
filtering, e.g. checking source addresses of IP datagrams close to the 
network edge. 

At RIPE-52 in Istanbul RIPE has established a task force that promotes 
deployment of ingress filtering at the network edge by raising
awareness 
and provide indirect incentives for deployment. 

Document ripe-379 provides the task force charter and the initial
time-line. 


The mailing list archive is at 
http://www.ripe.net/ripe/maillists/archives/spoofing-tf/2006/index.html 

The task force web page is at
http://www.ripe.net/ripe/tf/anti-spoofing/ 


The task force is co-chaired by Nina Hjorth Bargisen (NINA1-RIPE) 
and Daniel Karrenberg (DK58).

 Thank you for your information

Do you mean:

1) You are seeing BGP routes for addresses inside private space?

2) You are seeing packets with destination IPs inside private space
arriving at your interface from your ISP?

3) You are seeing packets with source IPs inside private space arriving 
at
your interface from your ISP?

If 1, feel free to filter them. You ISP probably uses them internally 
and
is leaking them to you. Feel free to complain if you want.

If 2, make sure you aren't advertising routes into RFC1918 space to your
ISP. If not, you should definitely ask them what's up.

If 3, that's normal. These are packets your ISP received that are 
addressed
to you and the ISP is leaving to you the decision of whether to accept them
or not. Feel free to filter them out if you wish. (It won't break anything
that's not already broken.)

From my experience, passively detecting how something is assembled on

What Steve says is the right thing to do.  Get off-net ask questions

Try http://www.hostip.info it is reasonable accurate in most cases and
hell it is for free. It depends what you need it for of course but it is
far better than nothing.

64.29.76.9, your mauigateway.com pops up correctly as Honolulu.
205.166.249.10 is guessed to be somewhere random in the US.

The problem with this one is that they are still gathering data and they
depend on user input, but it looks pretty accurate to what I have found
out.

Most of these kind of databases rely on user input though. I am quite
sure that Google, using their search thing and especially Orkut has
quite some info on this. Shopping Sites like Ebay and Amazon of course
get their shipping info for free and thus can pretty much pinpoint the
city correctly after $x percentage of customers bought from there.
Problem in the end is of course when there is a huge pool and the
end-users change a lot, but then the country is accurate enough already.

addresses being authoritative for TLDs is all run by one entity in a 
common location or set of locations.  UUNet is an exception to the 
location assumption.



The difference is that you are following the network and I'm following the
operator.


Thanks for sharing your data.

It's not really fair to baseline the credibility of
any geo location discussion based on hostip.info.

There are much better commercial services like Quovus,
MaxMind, and Akamai.

UltraDNS and PCH are anycast (there are several other anycast networks

Just for the record.

All name servers (a,b,c,d.ns.mx) of .mx are anycasted.

FCC Issues Second Order Mandating Internet Wiretapping Standards

2006-05-17 Thread Fergie

Pardon the interruption, but I thought this might be slightly
interesting to the list.

EPIC.org:

[snip]

The Federal Communications Commission (FCC) has released a second order 
reaffirming its decision to require that broadband and certain VoIP services be 
designed to make government wiretapping easier. This new order was issued 
despite the fact that a federal appeals court is considering a legal challenge 
to the FCC's initial decision to extend the Communications Assistance for Law 
Enforcement Act (CALEA) to the Internet.

In its second order, the FCC imposed new compliance deadlines, but refused to 
clarify exactly what service providers must do. CDT has led the appeals court 
challenge, which if successful will overrule the FCC order.

EPIC statement:

Second FCC CALEA order:

Now, back to your regularly scheduled programming.

You may be thinking of 'arrondissement', which means district.

'Abo', however seems to refer to subscribers:


I knew the word, but it was always associated in their rDNS with the
names of french towns

Moral - never try to translate french when you know just about enough
to order your dinner / call a taxi :)
