I had a similar issue, but it was mainly only over IPv6. According to someone I spoke to at Google, bumping up the MTU might help (and did help for me). I don't remember my previous MTU (I think it was 1280), but once I bumped it up to 1480 or so, my packets stopped getting routed to Europe (from NY) and worked properly. Maybe a similar issue could be with their IPv4 routers? Try increasing the MTU.

I am 100% sure "Pando Media Booster" do not give you the option of disabling it. Unless they hide it very, very deep.

If you read the article, you will see that Akami is one of the perpetrators, via the "Akamai NetSession Interface". :)

It is wonderful for CDN - for both legal and not-so-legal files. I however despise the game-loaders not giving you more options to control this traffic. For example, many run as a daemon that does not stop seeding - even when you're in-game. You could manually kill it, but it will re-run again. If you remove it, enjoy not being able to continue to play the game if it updates. "Pando Media Booster" (which I have had to deal with), detects your upload speed and uses about 3/4ths of it. The game installer never even had you accept an EULA - just when PMB.exe started when it was installed, it says on the bottom "you have accepted the EULA". EULAs don't really mean much now of days, sadly. This ruins the network quality, especially on large LANs, and most people don't even realize it's using all their connection. My personal verdict on it is: Give the users the option to limit the upload speed to whatever they want, and an option to disable it when they don't need to download any updates; if this is done, I personally see no problem with it. If this option is not added, I see it as malware that should be deleted. As I said above, I have no problems with using Bittorrent as a method of CDN - it's actually one of the best methods. But, the end-users need more control over it.

Re: Reverse DNS for IPv6 client networks

I haven't had my coffee yet this morning, so I may be misunderstanding you... I think you're asking for some way for your v6 subnet to both have proper forward and reverse DNS, right? If so, I personally find http://member.wide.ad.jp/~fujiwara/v6rev.html very useful. If you run a "normal" DNS server on the same IP, it probably will be hard to get it working. But, if you don't, it's pretty easy. You'd want to get v6rev.pl from the page above. Here is my config example: server_address: 0.0.0.0, 2001:470:892c:3432::1 server_port: 53 pid_file: /var/run/v6rev.pid reconfig_interval: 3600 reverse_domainname: c.2.9.8.0.7.4.0.1.0.0.2.ip6.arpa #/48 tbroker home reverse_domainname: 1.0.8.c.0.7.4.0.1.0.0.2.ip6.arpa #/48 tbroker work forward_domainname: dyn.harry.lu keyfile_dir: /home/v6rev/keys ttl: 3600 nsname: dyn.harry.lu enable_dnssec: 0 querylog: 1 static_ptr: 1.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.2.3.4.3.c.2.9.8.0.7.4.0.1.0.0.2.ip6.arpa harry.lu static_ptr: 5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.1.0.8.c.0.7.4.0.1.0.0.2.ip6.arpa staticsample.harry.lu Now, if you check the forward and reverse DNS entries for the subnets you defined in reverse_domainname: $ dig -x 2001:470:892c::7 +short 20010470892c0007.dyn.harry.lu. $ dig 20010470892c0007.dyn.harry.lu +short 2001:470:892c::7 Pretty cool, eh? You can also add in your own static ones on the same subnet using static_ptr. However, I bet I totally misunderstood your question!

It's not uncommon at all for a web-spider to find large files and download them. I don't think there's some conspiracy at Yahoo to find warez; they are just opperating as a normal spider, indexing the Internet. > ~500K/s (4Mbps+) for a 3 gig file is kinda... a bit harsh. What speed would you like a spider to download at? You could configure the speeds to Yahoo's blocks server-side if you care enough. Ideally, request your customer doesn't throw large programs on there if you're concerned about bandwidth. 4 Mb/s isn't abnormal at all for a spider, and especially on a larger file. > Is this expected/my own fault or what? A little bit of both :)
Geolocation tools - IPv6 style
Hello NANOG, first time writing to here. My inquiry for you is on the subject of IPv6 Geolocation tools; or better yet, the lack accuracy in them. My main problem comes from YouTube.com and other Google Geolocation required tools (Google Voice, being an example). I must set network.dns.disableIPv6 to true just to access a lot of videos on YouTube, and to access my Google voice and similar services. I am unsure what country it thinks I am from when I access via IPv6, but it sure thinks I am foreign to the US. I understand that all Geolocation can, at most, point to the local routing station of that person's ISP. The current progress in the IPv6 field of geolocation is mostly pointing at countries, not even states or cities unlike IPv4. Is there something majorly different about the ability to track IPs in v6, than there was in v4? Or are the main producers of this data just busy / do not see IPv6 as being profitable / not worth their time? Another problem I have (which isn't really relevant to the subject, but if anyone has the same problem when loading via IPv6 I would be interested in hearing about it), would be the loading of YouTube content. Pages will seemingly load partially, and always be "Waiting on s.ytimg.com". http://s.ytimg.com/ loads instantly for me via IPv6, but not via videos. Has anyone else experenced the same problem? If I use v4 to load YouTube, the video instantly loads. There could be heavy load from my broker (he.net), but all other sites load instantly. Thanks for your time.
