Well, coming up with a Mediawiki registration protocol that's hard to spam is apparently more difficult than I'd thought. For the moment, anyone who wants to contribute to the wiki, and to the expanded deployment of BCP38, is invited to toss a note to moderator [at] bcp38.info with a username, and we'll tell it to set you up an account and mail you a password manually. Sorry for the speedbump. I just want to tell you good luck. We're all counting on you. Cheers, -- jra -- Jay R.

Will a single /27 get fully routed these days?
by Drew Linsalata 27 Jan '14

27 Jan '14

Yeah, its been a while since I had to get involved in this. We have a customer with their own IPv4 allocation that wants us to announce a /27 for them. Back in "the day", it was /24 or larger or all bets were off. Is that still the case now?

hi there, i'm trying to figure out how i can redirect all the home router's traffic to a public server, using IPX and SPX (or in any other way). just a detail: i don't have access to the home router to change its configuration, and i have to do all this from Internet. i'm hoping someone here could enlighten me. thanks in advance!

China ISPs DNS problems on Jan 22nd - any idea what happened?
by Patrick van Staveren 27 Jan '14

27 Jan '14

This past Tuesday the 22nd I was witness to a widespread DNS poisoning problem in China, whereby a lot of DNS queries were all returning the same IP address, 65.49.2.178. Our websites became unavailable for most of our customers in China, as with many other websites. The major difficulty that we had with one of our websites is that we use Akamai's CDN, and Akamai's servers within China were unable to reach our origin server in London - so it originally appeared as if Akamai was having an issue before unofficial news surfaced that there was a larger problem going on. I have two questions for anyone: 1) I've found quite a bit of unofficial news [1] [2] on what happened, but does anyone know what *actually* happened? The only official news from the government that I can find says, "It was probably a cyberattack, but really, we don't know." [3] 2) As a website & network operator who strives to keep their product always available, is there anything I can actually do to prevent from this in the future? The most fun question I think everyone would love to know is - does anyone from Hurricane Electric have a throughput graph showing the traffic surge caused by this? It must be epic.

L2TPv3/MPLS (TP) Pseudowire to preserve
by Herro91 26 Jan '14

26 Jan '14

Hi, We have a new requirement to load balance across a couple of point to point ethernet links. The previous solution was handled by a few TDM circuits and MLPPP so that traffic was load balanced and any fragmentation/reassembly was handled by ML/PPP. Load balancing per flow is not really an option because we have a single IPSec tunnel (ESP-mode) and there is Layer 4 information to make a better decision to balance the load. I have been considering the use of L2TPv3 or an MPLS Pseudowire as a potential solution as they seem to have mechanisms to ensure packets are not misordered. I would appreciate any feedback/suggestions that the community can offer. Best, -Doug
