Update to the IPv4 Registry¹s Format and Content
by Leo Vegoda 21 Feb '08

21 Feb '08

This message has been sent to several lists. I apologise for duplicates. IANA has improved the format for the IPv4 Address Space registry. At the same time, the entries that were marked ³Various Registries² have been replaced with references to the Regional Internet Registry (RIR) that provides WHOIS and reverse DNS service for that /8 allocation. If you want to machine-process the IPv4 registry, the new fields are: * Prefix * Designation * Date * Whois * Status * Note where the Date will always be of the form ³YYYY-MM² and the status has the following possible values: RESERVED, LEGACY, ALLOCATED and UNALLOCATED /8 allocations that contain legacy assignments in them that are now managed by the RIRs have the text ³Administered by² in the Designation column. Legacy assignments refer to IP address allocations made before the RIR system was established. Reserved address space held by IANA does not have a date listed. The registry can be found at: http://www.iana.org/assignments/ipv4-address-space If you have questions about the structure of the new format, please send e-mail to iana(a)iana.org. Kind regards, Leo Vegoda Manager, Number Resources - IANA

2008.02.20 NANOG 42 IPv4 PTR queries for unallocated space
by Matthew Petach 21 Feb '08

21 Feb '08

Notes from day 4 of NANOG 42, we're on the home stretch now, so there's only a bit more of my spewage to wade through before we can resume our normal discussion of the imminent death of the internet as we know it. :) Again, apologies for typos, misspellings of names, etc. Matt 2008.02.20 opening remarks and analysis of PTR queries for IPv4 reserved addresses Trying to measure use of unallocated IPv4 address space Starting with Leo Vigoda, working at IANA now. leo.vigoda(a)icann.org At last NANOG, did lightning talk about how people were using unallocated space, but didn't show lots of data. Now, has a way to hopefully measure IPv4 addresses that people are trying to use. Not all the addresses, but at least one view of it. Problem? All unallocated unicast space will eventually be allocated; no more free /8's in the IANA pool at some point, as v6 won't get rolled out in time. Some people are using the same addres space that's currently in the 'unallocated' pool. Tried to measure it by looking at DNS queries at l.root for addresses in the unallocated blocks. root servers provide in-addr.arpa delegations, if a /8 isn't allocated, there's no delegation, so the root servers see the queries. Can't measure well-maintained networks with split-horizon DNS, or with good egress filters. Doesn't know how to measure truly private internal use; if you have ideas, let him know. Results slide; long blue line at the far left, lots and lots of queries, then shallows off to the right side; some old rubbish names in in-addr people are querying for. Left side is the fun stuff. 222/8, allocated to APNIC; not sure why it gets a lot more queries than the other /8's. Could be mail server lookups, since there's a lot of mail that comes out of 222/8; could be one rogue server. If you assume it's bogus, and chuck it out, data 'looks' better. 10/8 is near the top, as expected. 0/8 RFC3330 2/8 is unallocated; in the top 15 range. Odd there's unallocated space so close to the top of the queries range. If you take out all the unallocated stuff, there's still a lot of entries; looking at top 10 list: 2/8, 1/8, 23/8, 5/8, 100/8 is there at #5, which is odd. the next /8's they *were* going to give ARIN were 100/101, they decided to NOT give it out to figure out why there's so many hits on it in this round. The top 10 list is the 30 day period ending sunday; he also compared to statistics he used at the esNOG meeting in madrid a few months ago. Not very static; people leave top 10, new come on. 28dec-26jan, vs 19jan to 17feb 2/8 and 1/8 stay in #1 and #2 other /8s shift; 5/8 rises, 23/8 rises, 100/8 drops, 27/8 drops. It's not static, there's movement, people are shifting and shuffling blocks. Not measuring the query source address and AS # that could be gathered to inform people they're trying to talk to unallocated space. Only gathering from l.root, would be good to get data from other root servers. Leo's not a proper researcher, so would be good to get skillset from a real researcher. Would like to get data from nodes all over the world to get more global information; can see if there's more of a local component, or if this is a global phenomenon. This would be a very big data analysis challenge, combining l, k, and other root server operators, and get a more complete view of the data. Use it to either warn people, or help get things fixed if at all possible. Q: Louis Lee, Equinix, want to find out if they've looked to see if the top10 prefixes are in the global routing table when the queries come in? A: No, that hasn't been looked at, but a proper researcher would probably have considered and tied that data in as well. Q: Leo Bicknell, ISC: did they look at the source of queries? Are they all coming from a common resolver? A: no, not yet; would be the sort of thing that a proper researcher would be able to dig into. There are privacy considerations with looking at sources of queries, etc; needs to be thought through very carefully to make sure no per Q: Keith Mitchell, Interesting work, thanks Leo; there's lots of information for gathering, sharing, and protecting privacy in OIRC; if he would like to work with OIRC, they can give pointers on how to handle that data with necessary Q: further instrumenting to see if there's noise in the allocated space to see if this may be just part of overall background noise? A: this is the raw, basic data Q: Duane Wessels, measurement factory; DNS queries behave differently when a result exists vs doesn't exist; may be worthwhile to temporarily make them exist on a set of servers, and collect the data from there, and see if the resolution process follows the delegation. Q: Troy Jessup, Utah edu network; could 1, 2, 100, etc. network queries be due to malware that starts at one end of a block and just starts scanning indiscriminantly. 100 seems to be a common starting point for malware, for example. Haven't looked into it in that much detail--is it just 1.1.1.1/32, or 1.1.1.1/16, how much coverage within the block is there? is it just hot spots? These are really good ideas for the Real Researcher(tm) to delve into, once one can be tracked down. If people want to send suggestions, email him at leo.vigoda(a)icann.org

That's true. (Well, it's more like three years: there are currently 41 /8s available and last year, 14 were allocated to the RIRs.) I guess that means that people who want to use "off-label" address space should probably use the legacy /8s that are assigned but don't show up in the routing table.

2008.02.20 NANOG 42 IPv6 hour feedback and closing notes
by Matthew Petach 21 Feb '08

21 Feb '08

All done--thanks to CRG West for a kick-ass NANOG 42, and we'll see you all in Brooklyn in June! Matt 2008.02.20 Randy Bush, results of IPv6 hour from yesterday. Bill Fenner, Duane Wessels, and ???? Larry made it work to the extent that it did. Grabbed packet headers for the hour; did a simple distribution of IPv4, IPv6, and ARP. Should have subtracted out the NAT-PT traffic from v4, as it gets counted as both. most of the v6 traffic was NAT-PT; that's why v4 tracks v6 identically for the hour. When experiment started, amount of ARP traffic doubled. Duane was pinging the v4 addresses on the subnet; there were ARPs for offnet addresses. Some implementation seem to be making on-net assumption; with no default route, just try arping for it? Keep in mind the v6-xp had v4 but no default. MAC addresses associated to given SSID blue and white were V6 SSIDs, you can see that people *did* shift from the v4 to v6 SSIDs. nanog and nanog-a got double-counted, as they went to the same back-end; but it's still very clear most people tried switching to v6 SSIDs. Duane shows the pinging of v4 addresses during the hour. People definitely stopped trying to use v4 while it was turned off, and started again when they got back from lunch. Linux NAT-PT one known existing implementation http://tomicki.net/naptd.php Userpace based daemon had planned on using Cisco NAT-PT...but unable to make it work. Moved NANOG stats collector Linux box to trunk port configured 3 vlans for nanog-v6, nanog-xp-v6, It puts interface in promiscuous mode, listens for all packets, does translation in userspace. Uses DNS lookups, it synthesizes quad-A responses when there's no A response forthcoming. Daemon repeatedly appeared to hang Had to restart it numerous times Seemed to work better during v6 only hour. There's also v6 on regular networks, could be hanging due to nat-pt box seeing v6 on the main nanog/nanog-a networks (outside). cacti graphs, total traffic through CRG-West 20m to noon, drops to 2-3M, 12:20 NAT-PT started working better, hit 10Mb, drops at 1300 for lunch. total number of associations on APs; peaked at 314 early, at noon drops down to about 100 clients at noon; went up to about 175 during the hour. that's just layer 2 association; but the previous traffic was indeed showing there was some v6 happening. Collected *lots* of "these need to be fixed" data as well for vendors. Jay Hennigan, Impulse Internet--used nanog-v6 and it's getting much better performance than it was during the v6 hour. competition for resource, or need for it to listen to all three networks, could be a bit of a reconfiguration that helped get things going. Closing comments from Todd Very impressive turnout for a four day NANOG! Thanks to CRG-West, wonderful hotel, party last night, many thanks to break sponsors, they help keep the conference price reasonable for us. Statistics! 575 registered attendees (483 paid) 20% ISP 21% network operator 18% equipment vendor 12% content provider 6% research 2% government bunch of ISP folks moving to content houses top countries 488 US 19 Japan 13 UK 11 Canada 20 others orgs: 41 Cisco 16 juniper 14 equinix 13 CRG West Much related to close travel for them. ;) FILL OUT YOUR SURVEY! www.nanog.org! Need to know what was good, what was bad. NANOG43 in Brooklyn, June, TelX is sponsoring it, will be a fantastic, impressive logistical feat given hotel prices in NY; getting price under $200/night is very, very impressive. Program Committee--huge kudos for getting program out soon enough for people to make plans around it. If you have ideas for presentations, come talk to the yellow badged people! If you can help, talk to the yellow badge people! And FILL OUT YOUR SURVEY!

2008.02.20 NANOG 42 Morpheus, flexible interdomain routing
by Matthew Petach 21 Feb '08

21 Feb '08

Two more sets of notes to go. :) Matt 2008.02.20 Morpheus, enabling flexible interdomain routing policies Yi Wang, Princeton, along with Ioannis and Jennifer. Goal is to get feedback from operators on how useful this would be for getting more usage out of links. Large ISPs have rich path diversity top 2% ASes have 10 or more AS paths for many destinations 5-10 router-level paths for many destinations Different paths have different security levels prefix/subprefix hijacking is a concern avoid an undesirable AS on a path for better performance. today, customers may want different paths; finance wants security, content wants high bandwidth, voip wants low latency/jitter. No "one-size-fits-all" but today, we just have 'one route fits all' Morpheus routing control platform that enables a single ISP to flexibly pick paths for different customers. intra-AS routing architecture it's backward compatible no changes to the routers Use separate morpheus servers to pick the best routes for the routers. Not all routers have to have full set of information. Use MPLS tunnels or IP-in-IP to carry information. Support for multipath already available virtual routing and forwarding on Cisco virtual router on Juniper Limitations of current BGP attributes 1) overloading of BGP attributes localpref used for both business relationships and traffic engineering 2) difficult to incorporate side information (measurement data, business relationships, registry information, history of prefix/origin, route stability) Inside morpheus server: policy objectives as independent modules. Each module tags routes in separate spaces (solves limitation 1) easy to add side information (solves limitation 2) different modules can be implemented independently (eg by third parties) -- evolvability This way, you can take best from multiple vendors or third parties and wrap them together. 3) BGP strictly ranks attributes one over the next; no way to make tradeoffs between policy objectives Use weighted sum instead of strict ranking After a set of classifiers applied, you specify a weight to see which set of heuristics get used. Allow for multiple decision processes running in parallel each with a different set of requirements, and a different set of weights, resulting in different path selections. Prototype implementation in XORP pipeline of classifier modules Classifier works very efficiently total decisiontime graph Morpheus is faster than the standard BGP decision process, when there are multiple alternative routes for a prefix. Evaluation environment 40 pops, 1 morpheus server in each pop each morphous server with 240 peers Morpheus can support a large number of decision processes in parallel; tested up to 40 DP in parallel. no threat to stability only announce non-default routes to stub customers a significant portion of customers are stubs. provides a simple, extensible, flexible way for ISPs to practically control traffic. He has questions for operators on how they set weights, and adjust policies for customers, and how much control they might be willing to give to customers; send feedback to yiwang(a)cs.princeton.edu Q: Todd asks how you have upstream routers making decisions based on differences in source information? A: Goal is to use different tunnels for different customers; so you tunnel to outgoing interfaces to direct your traffic to where you want it. Q: Randy Bush, IIJ, after years of trying to get resiliency over the networks; what happens when the central server fails? Does it revert back to normal routing? A: It's a typical distributed system; every server has a complete view of your routing information. Use multiple servers for a given edge router; so every edge router peers with two different Morpheus servers. But what happens when both fail? The engineers will work hard to bring them back up. And probability of both failing will be much lower than if just one fails. Q: He mentions connections between Morpheus servers; how is that handled--is it proprietary? A: No, not proprietary, more like using BGP AddPath extension, and use BGP as the framework for it.
