12u Colo+power in Level3, Orlando, TOMORROW
by david raistrick 19 Sep '07

19 Sep '07

Guys, I hate to send this to nanog, and please direct all replies offlist....but this is a flat out last ditch effort to keep from losing a customer. I need about 12u of space @ 380 S. Lake Destiny Rd, Orlando FL and AC power for it (details on that not yet known, 10 dell PE1950s), and I need it tomorrow. This is the Level3 Gateway colo facility in Orlando. We can do daily, weekly, monthly, yearly, whatever, just have to get these boxes online. Other facilities are not an option unless you can also provide a 1G crossconnect from the L3 building by tomorrow. ;) Root problem is that we got caught with no power...and L3 has no more power to give. :( thanks, and sorry for the offtopic. --- david raistrick http://www.netmeister.org/news/learn2quote.html drais(a)icantclick.org http://www.expita.com/nomime.html

What's the real issue here?
by NetSecGuy 19 Sep '07

19 Sep '07

:~> whois 97.81.31.19 Unknown AS number or IP network. Please upgrade this program. Is this a function of whois hardcoded to no do lookups for this address space? I can't seem to find any info about the range, beyond "registered but unallocated". I figured whois would at least return something about it not being allocated. Is this hijacked space?

Standard prefix length filtering
by chk 543 19 Sep '07

19 Sep '07

Is there a standard prefix length most providers filter on, or is there a way to find out what each provider filters on? We have been assigned a /22 and are wondering if we will have any issues with this block. --------------------------------- Fussy? Opinionated? Impossible to please? Perfect.

You are free to "assume" anything you feel like in the design of a new protocol. The greater the divergennce between your 'assumptions' and *UNIVERSALLY* IMPLEMENTED conditions in the real world, the more barriers there are to acceptance and deployment. Within a single administrative domain, routers are 'usually' -- but *NOT* "almost always" -- moderately closely synchronized. Across different administrative domainns, any such synchronization is 'happy accident', nothing more. As far as 'assuming clock synchronization' goes, one of the other subscribers to this list has a _very_ applicable remark: "I encourage my competitors to design like this." <grin>

Providers providing native IPv6
by Jeroen Massar 18 Sep '07

18 Sep '07

Hi, As some of you might know we maintain a list of ISP's that provide IPv6 connectivity to endusers, thus over Cable/DSL/PPP etc. This list is at: http://www.sixxs.net/faq/connectivity/?faq=native If you have any additions/changes for that, don't hesitate to spam the details to me offlist so that they can be updated. Product URL's are of course very welcome also for that purpose. There is another page listing Transit suppliers who can do native IPv6 for you: http://www.sixxs.net/faq/connectivity/?faq=ipv6transit For tunnel providers, there is a 3rd list at: http://www.sixxs.net/tools/aiccu/brokers/ As a Q to the list, as we also have the data for GRH available, thus effectively every ISP that would be able to provide IPv6, would it maybe be better to add a link to the 'product' pages from there and tag prefixes where endusers can get it and how? Greets, Jeroen (As for the Q why we (SixXS) maintain a list of native and other IPv6 providers which would mean we would loose customers: when there is native IPv6 from ISP's then we can shut that part of the project down and go do other fun things ;)

Quick quotes please for 100Mbit and 1gbit UK routing table traffic located in RedBus Sovereign House
by Andrius Kazimieras Kasparavičius 17 Sep '07

17 Sep '07

Hi, I've got a few companies keen to buy "cheaper" "local" LINX traffic. As they are too small to register at RIPE and buy LINX fees and peer, I believe, out there should be companies selling transit to UK routing table at LINX. Aternative UK's IXs would be of interest too. Is it viable service for ISPs these days? Any referals would be appreciated. Thanks
