v6 subnet size for DSL & leased line customers
by Scott Weeks 03 Jan '08

03 Jan '08

Disclaimer: I'm still very much an IPv6 wussie... :-) --------------------------------------------- But even in 2000 the policy was and still is: /128 for really a single device /64 if you know for sure that only one single subnet will ever be allocated. /48 for every other case (smart bet, should be used per default) ---------------------------------------------- I work on a network with 100K+ DSL folks and 200+ leased line customers, plus some other stuff. The leased line customers are increasing dramatically. I should plan for a /64 for every DSL customer and a /48 for every leased line customer I expect over the next 5-7 years? scott

periodic patterns in juniper netflow exports
by Fernando Silveira 03 Jan '08

03 Jan '08

hi there, I'm analyzing NetFlow traces from Abilene (which uses Juniper, of course) and I'm seeing a periodic pattern in the traces. I know about the activity and inactivity timeouts that can be set in JunOS to control flow exports, but in the data I'm analyzing it seems like there is some kind of global clock that flushes the flow cache every minute. I mean the router exports *all* flows which are active at the end of a time bin of one minute. Because of this, the flow records look like they are binned in 1 minute intervals. By the way, I'm not talking about any manipulation done by the collector. I'm really looking at the FIRST and LAST time stamps contained in each flow record. Can anyone tell me if there is such a timer in JunOS, i.e., flushing the flow cache every minute (or an interval defined as a parameter)? Thanks in advance and happy Hew Year! Fernando Silveira

European ISP enables IPv6 for all?
by Sean Siler 03 Jan '08

03 Jan '08

In a recent Slashdot article (http://slashdot.org/articles/07/12/17/1451230.shtml) discussing IPv6, someone left a comment the read, in part "One of the largest IPSs (sic) in Europe turned on IPv6 to all 8 million users this week. They've done the right thing and made it opt-in for now, their customers have to go to their control panel web page and turn it on, but almost 50,000 people did in the first 24 hours." Does anyone know which ISP the poster is talking about? Is there any truth to this at all? Any feedback appreciated. Sean Siler IPv6 Program Manager Microsoft

Assigning IPv6 /48's to CPE's?
by Rick Astley 03 Jan '08

03 Jan '08

I see there is a long thread on IPv6 address assignment going, and I apologize that I did not read all of it, but I still have some unanswered questions. I believe someone posted the ARIN recommendation that carriers assign out /64's and /56's, and in a few limited cases, /48. I can understand corporations getting more than a /64 for their needs, but certainly this does not mean residential ISP subscribers, right? I can understand the need for /64's because the next 64 bits are for the client address, but there seems to be this idea that one and only one node may use a whole /64. So in the case of Joe, the residential DSL subscriber who has 50,000 PCs, TiVo's, microwaves, and nanobots that all need unique routable IP addresses, what is to stop him from assigning them unique client ID's (last 64 bits) under the same /64? We can let Joe put in some switches, and if that isn't enough he should consider upgrading from his $35/month DSL or $10/month dial up anyway. My next question is that there is this idea that there will be no NAT in the IPv6 world. Some companies have old IPv4 only software, some companies have branch offices using the same software on different networks, and some like the added security NAT provides. There are also serious privacy concerns with having a MAC address within an IP address. Aside from opening the doors to websites to share information on specific users, lack of NAT also means the information they have is more detailed in households where separate residents use different computers. I can become an IPv4 stranger to websites once a week by deleting cookies, IPv6 means they can profile exactly what I do over periods of years from work, home, starbucks, it doesn't matter. I don't see NAT going away any time soon.

Expecting that in v6 these requirements will evaporate is not wise. There will have to be some useful TE knobs, I think the operations community would probably like to see those knobs NOT be 'deaggragate' so what other options are there for someone with a single prefix (especially when that prefix is very large). ----------------------------------------------------- I just want to echo agreement with Chris' repeated comments (but seemingly unanswered as of yet) on these issues. scott

Too late once they've announced them As with v4 if the herd doesn't stay together on policy then once some have accepted the rest get picked off one by one as their customers complain (I've watched a smaller ISP try filtering v4, sucks to be them) If there is to be a deaggregation limit it needs to be universal and set up already so people don't try to annouce. Doesn't work is a better argument than some will try and stop it working. Game on. brandon
