They are not my own, so by saying that I am not plagiarizing you folks who were kind enough to reply to me... :-) Last, it is not my intention to start any kind of religious war on the subject. Only to inform folks that're at my level of IPv6 understanding or below how to get started on planning, so they can then get around to obtaining their block. Please let me know if my math is wrong. All subnets (wrong term I'm told, but I'm going to use it anyway) should be a /64 as things like privacy addressing, stateless autoconfiguration and other stuff rely on that being the default subnet size. This includes my example of a home DSL line. Households will most likely need more than one subnet as in the future things like wireless gateways might want to create routed topologies, rather than bridging everything into a single subnet. For example, perhaps I don't want my microwave and refrigerator on the same subnet as my television on the same subnet as my TiVO on the same subnet as my computers. Once you accept the need for more than one /64 subnet in a household or business, you start looking at a /56 or a /48. A /56 is 256 /64 subnets and a /48 is 65536 /64s. At this point you need to know your customer base. For example, will 256 subnets (a /56) be enough for a business? In my case, /56s will work, but I will interleave empty blocks in the assigned blocks just in case. A /32 is 2^24 /56s and is the normally assigned block from ARIN. This is ~16.8 million /56s, which allows ~8.4 million customers to have 256 /64 subnets each. My brain numbs at the thought of the numbers we're dealing with... scott

Either type of customer here in Hawaii probably won't get close to using that many addresses. Would I get any other benefit from all blocks being the same size? scott

Using RIR info to determine geographic location...
by Drew Weaver 20 Dec '07

20 Dec '07

Is this becoming a more common or less common practice as we slide ourselves into the last week of 2007? The reason I am wondering is we have noticed some 'issues' recently where correct info in the RIR causes very inefficient and sometimes annoying interaction with some of the world's largest online applications (such as Google) lets say for example that a customer in India purchases dedicated server or Co-Location hosting at a HSP in the United States [very common]. So the RIR shows that the customer is in India, so when the customer interacts with any google applications google automatically directs this traffic to google.in (or the India version of whichever app).... More unfortunate than this fact, is the fact that it appears that services and application providers such as google are caching RIR data for an "unknown" amount of time. Which means that if a service provider SWIPs an allocation to a customer (lets use the same example... again in India) (say a /24) to a user, and then that user subsequently returns that allocation and the service provider re-allocates in smaller blocks to different customers in say /29, /28.. et cetera... the problems related to this issue are compounded (30 customers being affected, instead of one...) by this caching... Obviously providing RIR information is the responsibility of service providers (it is even ARIN's policy) has anyone else in the community ran into issues such as this and found solutions or workarounds? Happy holidays to all on NANOG :D Thanks, -Drew

Well, if you can scan the whole space (at 15 kpps 80 hours for the entire IPv4 space although with random generation it's going to take longer than that) sparseness isn't a huge issue. If you can't scan the whole space (at 15 kpps 7.1 x 10^26 years for the entire IPv6 space) then sparseness becomes a consideration. But I still don't see how random scanning is going to do you much good: either so few IPv6 hosts are vulnerable that scanning for them isn't worth the time, or so many that if you can scrape some IPv6 addresses from the web you can infect those and they'll infect all the networks they connect to (scanning a LAN locally is easy).

It's kind of interesting that from 2001ish to current day and there is still only a handful of service providers worldwide that seem to offer *any* kind of support for IPv6. After all the propaganda, is there actually any other major deployments in the IPv6 space? >From the ipv6.org web site, I see "Most of today's internet uses IPv4, which is now nearly twenty years old." - read as it works well! " IPv4 has been remarkably resilient in spite of its age, but it is beginning to have problems." - Really? Every network I know using IPv4 still works as designed. "Most importantly, there is a growing shortage of IPv4 addresses, which are needed by all new machines added to the Internet." - I'm sure there's a lot more ways around this - and I'm sure the NANOG archives have a lot of thought food there. "It also adds many improvements to IPv4 in areas such as routing and network autoconfiguration." - I would really love to know what these are that DHCP etc doesn't already do. I tried to check out the FAQ at http://faq.v6.wide.ad.jp/ but it wasn't reachable - maybe it needs IPv6 connectivity? As for routing 'improvements', doesn't more address space just give us more routes to handle? "IPv6 is expected to gradually replace IPv4, with the two coexisting for a number of years during a transition period." - so this 'transition period' has been, what, 7 years so far? I'm still predicting that it'll be at least another 10 years before IPv6 amounts to much... On a side note, does anyone currently have issues getting new address space where it's operationally required? I don't know anyone first hand who has yet to come across this issue... -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9001 6090 - 0412 935 897 C:\WINDOWS C:\WINDOWS\GO C:\PC\CRAWL

VSNL CANTAT-3 Optical Submarine Cable
by Martin Hannigan 18 Dec '07

Dear Colleagues: I've had multiple conversations with operators concerning the status of CANTAT-3, a submarine cable that runs from Pennant Point , Halifax, Canada, to the area of Sylt, DE and branches to locations along the route: http://upload.wikimedia.org/wikipedia/commons/3/3b/CANTAT-3-route.png 1. Pennant Point , Nova Scotia Canada 2. Vestmannaeyjar, Iceland 3. Tjørnuvík, Faroe Islands 4. Red car, England, UK 5. Blaabjerg, Denmark 6. Sylt, Germany Does anyone have formal or published indication from VSNL that confirms a decommissioning and states an actual date? I've heard this from several highly reliable sources and I'd like to find out "when" if at all. I have checked Google. I'd be very happy to receive any information formally, off line, or otherwise and summarize back to the list. Best, Marty

Someone else mentioned "self-infliction" in this thread, and that's spot on. Over the course of the past year or more, we've seen less & less "scanning & self-propagating" malware, and more & more self-infliction, either by being duped via social engineering or just by drive-by infections/compromises. As it stands, now -- and unless the pendulum swings the other way -- the whole "...v6 address space is larger, thus it is much harder to scan and thus propagation of worms is much harder..." train of thought is completely misguided. - - ferg -----BEGIN PGP SIGNATURE----- Version: PGP Desktop 9.6.3 (Build 3017) wj8DBQFHZ+v6q1pz9mNUZTMRAviAAKC1z/Q0m1xzFmSkah5WL8xrbD/cEgCfaKgi xQHKSq8Tx8D5JEv6ObrGVoQ= =mdeP -----END PGP SIGNATURE----- -- "Fergie", a.k.a.
