RBN and it's spin-offs
by Bruce Williams 02 Jan '10

02 Jan '10

Interesting article about RBN, it's spin-offs and the global network infrastructure used for cybercrime. Has a passing mention of Atrivo's place in the global picture. http://www.newsweek.com/id/228674 Reportedly started by someone operating under the name "Flyman," RBN is known as the mother of cybercrime among online investigators. François Paget, senior expert for the McAfee company, says that RBN began as an Internet provider and offered "impenetrable" hosting for $600 a month. This meant a guarantee that it would not give out information about its clients, no matter what business they were in. Aleksandr Gostev, director of Kaspersky Labs, a global research and threat analysis center, believes that RBN's servers are located in Panama. "Confidential data about clients can be obtained only by a court decision," a Newsweek source familiar with the situation says. "But what court do you apply to if criminal ties are discovered? A Panamanian court?" -- Bruce Williams “Discovering...discovering...we will never cease discovering... and the end of all our discovering will be to return to the place where we began and to know it for the first time.” -T.S. Eliot

RE: dark fiber and sfp distance limitations
by Carlos Alcantar 02 Jan '10

02 Jan '10

In my experience in leasing dark fiber strands over long distance the providers usually give the option for regen colo space. And in some cases they wanted to know full specs of the equipment you are going to be using so there is no questions if it will work or not. Carlos Alcantar Race Telecommunications, Inc. 101 Haskins Way South San Francisco, CA 94080 P: 650.649.3550 x143 F: 650.649.3551 E: carlos(a)race.com -----Original Message----- From: Mike [mailto:mike-nanog@tiedyenetworks.com] Sent: Friday, January 01, 2010 2:53 PM To: nanog(a)nanog.org Subject: dark fiber and sfp distance limitations I am looking at the possibility of leasing a ~70 mile run of fiber. I don't have access to any mid point section for regeneration purposes, and so I am wondering what the chances that a 120km rated SFP would be able to light the path and provide stable connectivity. There are a lot of unknowns including # of splices, condition of the cable, or the actual dispersion index or other properties (until we actually get closer to leasing it). Its spare telco fibers in the same cable binder they are using interoffice transport, but there are regen huts along the way so it works for them but may not for us, and 'finding out' is potentially expensive. How would someone experienced go about determining the feasibillity of this concept and what options might there be? Replies online or off would be appreciated. Thanks.

2009 IPv6 Address Use Report
by Iljitsch van Beijnum 02 Jan '10

02 Jan '10

[ (Non-cross)posted to NANOG, PPML, RIPE IPv6 wg, Dutch IPv6 TF. Web version for the monospace font impaired and with some links: http://www.bgpexpert.com/addrspace-ipv6-2009.php ] 2009 IPv6 Address Use Report Since 2005, I've been compiling an IPv4 address use report every year. With the start of the new decade, this is a good moment to start doing the same thing for IPv6. http://www.bgpexpert.com/addrspace-ipv6.php shows the amount of IPv6 space given out by RIR and by year, while http://www.bgpexpert.com/ipv6addressespercountry.php shows the amount of IPv6 address space by country. Both these pages are updated weekly from the delegation data that the RIRs publish on their FTP servers. 2008 saw a huge increase in the amount of IPv6 space given out and then a big drop in 2009 (amounts of IPv6 address space in the equivalent of /32s): 1999 10.88 /32s in 17 blocks 2000 19.75 /32s in 32 blocks 2001 33.13 /32s in 61 blocks 2002 156.75 /32s in 271 blocks 2003 261.38 /32s in 290 blocks 2004 13340.63 /32s in 295 blocks 2005 26985.00 /32s in 245 blocks 2006 9798.00 /32s in 243 blocks 2007 6687.01 /32s in 491 blocks 2008 81012.02 /32s in 886 blocks 2009 1091.03 /32s in 1280 blocks However, this is not the complete picture. The large number for 2008 is the result of two unusual events. The first one is LACNIC's delegation of the 2804::/16 block to the Brazilian national internet registry (NIR). At some point in the future, the delegation records will not show such blocks as "used" in their entirety anymore. Also, ARIN delegated 14 /22 blocks within the range 2608::/13 to the US Department of Defense. With these two artifacts removed, the amount of IPv6 space given out per year looks like this: 1999 11.00 /32s in 17 blocks 2000 20.00 /32s in 32 blocks 2001 33.00 /32s in 61 blocks 2002 157.00 /32s in 271 blocks 2003 261.00 /32s in 290 blocks 2004 13341.00 /32s in 295 blocks 2005 26985.00 /32s in 245 blocks 2006 9798.00 /32s in 243 blocks 2007 6687.00 /32s in 491 blocks 2008 1140.00 /32s in 871 blocks 2009 1091.00 /32s in 1280 blocks So the number of blocks given out keeps increasing, but their size is going down. There are two reasons for this: roughly between 2004 and 2006, RIPE and APNIC gave out some very large blocks to some very large ISPs. They mostly stopped doing that. And provider independent blocks started to be allowed and are getting more and more popular. These are the /32 - /35 allocations. /32 is the minimum block size given out to ISPs, this used to be /35. So this view shows the numbers of small-to-medium sized ISPs obtaining IPv6 address space: 1999 11.00 /32s in 17 blocks 2000 20.00 /32s in 32 blocks 2001 33.00 /32s in 55 blocks 2002 157.00 /32s in 254 blocks 2003 223.00 /32s in 251 blocks 2004 235.00 /32s in 241 blocks 2005 217.00 /32s in 217 blocks 2006 186.00 /32s in 186 blocks 2007 351.00 /32s in 351 blocks 2008 734.00 /32s in 734 blocks 2009 1011.00 /32s in 1013 blocks These are the blocks larger than /32 that go to large ISPs (excluding the BR NIR and DoD blocks): 2003 38.00 /32s in 3 blocks 2004 13106.00 /32s in 9 blocks 2005 26768.00 /32s in 13 blocks 2006 9612.00 /32s in 14 blocks 2007 6336.00 /32s in 8 blocks 2008 406.00 /32s in 7 blocks 2009 80.00 /32s in 4 blocks And these are the blocks smaller than /35, which are now mostly provider independent blocks, but also "critical infrastructure", such as root servers get a /48 block: 2001 0.00 /32s in 6 blocks 2002 0.00 /32s in 17 blocks 2003 0.00 /32s in 36 blocks 2004 0.00 /32s in 45 blocks 2005 0.00 /32s in 15 blocks 2006 0.00 /32s in 43 blocks 2007 0.00 /32s in 132 blocks 2008 0.00 /32s in 130 blocks 2009 0.00 /32s in 263 blocks So after a small dip in 2006, the number of small-to-medium sized ISPs obtaining IPv6 address space shows a steady upward trend, but apparently the very large ISPs either already got their IPv6 address space, are not focussing on IPv6 right now, are starting with a small block (or several small blocks), or a combination of all of these factors. Even with the BR NIR and DoD blocks included, the (equivalent of) 39395.56 /32s given out in 4111 blocks is only 0.026% of the 536870912 possible /32s in the currently defined global unicast space (2000::/3). For comparison, the number of IPv4 blocks given out is 99562.

Restrictions on Ethernet L2 circuits?
by Endresen Even 01 Jan '10

01 Jan '10

Hello, Anyone with opinions on what restrictions a service provider should and should not impose on Ethernet L2 circuits provided to business customers wanting to connect several offices? The service provider's MPLS core network doesn't mind what traffic flows through the EoMPLS tunnel, but the L2 access network do mind and can be vulnerable to several layer 2 issues. Broadcast storm control and BPDU filter will protect the access network to a certain degree, but there are still potential layer 2 problems that can affect the switches, for example MAC address spoofing/flooding. Not to mention potentially difficult troubleshooting if a business customer connects two large LANs through the ISP's Ethernet layer 2 circuit, and then experience some occult layer 2 problem. Should business customers expect to be able to connect several LANs through an Ethernet L2 ciruit and build a layer 2 network spanning several locations? Or should the service provider implement port security and limit the number of MAC addresses on the access ports, forcing the customer to connect a router in both ends and segment their network? Also, do you see a demand for multi-point layer 2 networks (requiring VPLS), or are point-to-point layer 2 circuits sufficient to meet market demand? The most important argument for customers that choose Ethernet L2 over MPLS IP-VPN is that they want full control over their routing, they don't want the involvement from the service provider. Some customers also argue that a flat layer 2 network spanning several locations is a simpler and better design for them, and they don't want the "hassle" with routers and network segmentation. But IMO the customer (and the service provider) is far better off by segmenting their network in the vast majority of cases. What do you think?

Re: Restrictions on Ethernet L2 circuits?

Linen, > As far as I'm concerned, enterprises should just connect their various sites to the Internet independently, and use VPN > techniques if and where necessary to provide the illusion of a unified network. In practice, this illusion of a single > large LAN (or rather, multiple organization-wide LANs) is very important to the typical enterprise, because so much > security policy is enforced based on IP addresses. And the typical enterprise wants a central chokepoint that all traffic > must go through, for reasons that might have to do with security, or support costs, or with (illusions of) control. Most security policies are also based on 'local" vs "remote" criteria. Most pieces of software believe that an access to a local IP is faster and safer than accesses to an IP address somewhere else. Emulate means lying to someone, and if you start lying too much you can end up messing everything. I agree that enterprises should use WANs as WANS (i.e., IP routed networks) and don't try to hide distance and security fragility from systems and security appliances. End to end VPN can be used in the very special cases where a special security is needed, by means of strong VPN encryption. It seems nice to have something that looks like a simple Ethernet cable. The problem is that it is *not* a simple cable, and will never be. Make the rest of the LAN believe that it is such a simple cable may raise huge trouble. Most of LAN protocols have a degree of TRUST on LAN traffic. Any security expert will tell you that trust is your enemy. Managing a router is a hassle? Oh, come on! If a net admin is unable to manage a simple sub net configuration and so some simple math with masks and prefixes he would rather find himself another job. Take care, A.B. Jr.
