AS 9583 (Sify Corp) contact required
by Scott Larson 20 Mar '17

20 Mar '17

Beginning at 10am UTC today, AS 9583 began announcing routes for our (AS 40041) IP space, the most significant damage of which has so far been caused in the UK. We're currently playing whack-a-mole on an ISP and exchange level, but having zero luck tracking down a contact capable of a proper resolution to this issue. Please contact me off list if you are that person or know who they are. *[image: userimage]Scott Larson[image: los angeles] <https://www.google.com/maps/place/4216+Glencoe+Ave,+Marina+Del+Rey,+CA+9029…>Lead Systems Administrator[image: wdlogo] <https://www.wiredrive.com/> [image: linkedin] <https://www.linkedin.com/company/wiredrive> [image: facebook] <https://www.twitter.com/wiredrive> [image: twitter] <https://www.facebook.com/wiredrive> [image: instagram] <https://www.instagram.com/wiredrive>T 310 823 8238 <310%20823%208238%20x1106> *

Purchased IPv4 Woes
by Pete Baldwin 20 Mar '17

20 Mar '17

Hi All, Hopefully this is not taken in bad taste. Our organization purchased some IP space last year (163.182.192.0/18 to be specific), and it appears that this block must have been used for less-than-admirable purposes in the past. We have been trying to clean up the reputation where possible, and we do not appear to be on any blacklists, but we do appear to be blocked from a lot of networks across the US/Canada. I am noticing a lot of name servers blocking our requests, many web servers, gaming servers, mail etc. This is a transition block for us to move towards v6 everywhere, but we have many systems that will need to rely on this block of space for some time to come. We are a small rural co-op ISP in Ontario, and I am just writing this email as an extra plea so that if you happen to run a network that has this entire range on your naughty list, we would appreciate you giving it another chance. I can be contacted on or off list, thanks. -- ----- Pete Baldwin Tuckersmith Communications (P) 519-565-2400 (C) 519-441-7383

IPv6 oddness in Comcast land...
by valdis.kletnieks＠vt.edu 20 Mar '17

20 Mar '17

Trying to figure out what the heck is going on here. Any good explanations cheerfully accepted. Background: Home internet router is a Linksys WRT1200AC that had been running OpenWRT 15.05.01. IPv6 worked just fine - Comcast handed me a /60 via DHCP-PD and no issues. I reflashed it to Lede 17.01, and after doing all the reconfig, I'm hitting a really strange IPv6 issue. Symptoms - IPv6 still configures correctly, but IPv6 packets appear to go out and disappear into the ether when they leave the Linksys. Doing a traceroute to any IPv6 destination makes things work again - for a while (from 15 minutes to an hour or two). As seen from my laptop (I have the matching tcpdump from the outbound interface on the Linksys): [~] ping -6 -c 3 listserv.vt.edu PING listserv.vt.edu(listserv.ipv6.vt.edu (2001:468:c80:2105:211:43ff:feda:d769)) 56 data bytes --- listserv.vt.edu ping statistics --- 3 packets transmitted, 0 received, 100% packet loss, time 2070ms [~] traceroute -6 listserv.vt.edu traceroute to listserv.vt.edu (2001:468:c80:2105:211:43ff:feda:d769), 30 hops max, 80 byte packets 1 2601:5c0:c001:69e2::1 (2601:5c0:c001:69e2::1) 2.417 ms 3.077 ms 5.358 ms 2 * * * 3 * * * 4 * * * 5 * * * 6 * hu-0-10-0-7-pe04.ashburn.va.ibone.comcast.net (2001:558:0:f5c1::2) 31.478 ms 31.975 ms 7 2001:559::d16 (2001:559::d16) 32.406 ms 17.102 ms 24.751 ms 8 2001:550:2:2f::a (2001:550:2:2f::a) 23.245 ms 23.519 ms 22.185 ms 9 2607:b400:f0:2003::f0 (2607:b400:f0:2003::f0) 29.782 ms 28.604 ms 29.891 ms 10 2607:b400:90:ff05::f1 (2607:b400:90:ff05::f1) 30.423 ms * 30.680 ms 11 * * * 12 listserv.ipv6.vt.edu (2001:468:c80:2105:211:43ff:feda:d769) 34.562 ms 39.072 ms 24.633 ms [~] ping -6 -c 3 listserv.vt.edu PING listserv.vt.edu(listserv.ipv6.vt.edu (2001:468:c80:2105:211:43ff:feda:d769)) 56 data bytes 64 bytes from listserv.ipv6.vt.edu (2001:468:c80:2105:211:43ff:feda:d769): icmp_seq=1 ttl=53 time=33.3 ms 64 bytes from listserv.ipv6.vt.edu (2001:468:c80:2105:211:43ff:feda:d769): icmp_seq=2 ttl=53 time=24.3 ms 64 bytes from listserv.ipv6.vt.edu (2001:468:c80:2105:211:43ff:feda:d769): icmp_seq=3 ttl=53 time=46.0 ms --- listserv.vt.edu ping statistics --- 3 packets transmitted, 3 received, 0% packet loss, time 2003ms rtt min/avg/max/mdev = 24.334/34.595/46.093/8.927 ms So it looks like something times out somewhere and fails to pass packets back. TCP connections don't keep IPv6 alive. I have a browser window that auto-updates every 5 minutes, and a SmokePing process on a Raspberri Pi uploads to a server at work every few minutes, and those eventually drop back to IPv4 when the IPv6 TCP fails to connect. And normal UDP doesn't seem to keep it alive - NTP pointing at IPv6 peers loses connectivity as well. But a traceroute wakes it up. It's almost like some router is losing the route to me out of the FIB, and fixes it when it has to handle a packet on the CPU slow path (like send back a 'time exceeded'). But I'm mystified why this started when I reflashed my router.

difference with caching when connected to telia internet
by Aaron Gould 18 Mar '17

18 Mar '17

Regarding, caching services like Netflix OCA and Google GGC, does anyone know if there is something strange that occurs when connected to Telia BGP AS1299 ? .meaning, if I have local Netflix/google caches, and then later I establish a BGP session for Internet with Telia/BGP 1299, would there be something that would make netflix and google caches reachable via Telia look better than my local ones ?! -Aaron

Government agency renting or selling IP space
by Mel Beckman 17 Mar '17

17 Mar '17

I have a government agency client with a number of /24s that they acquired back in the 1990s when they operated as an ISP for other agencies. They are interested in renting or selling these addresses. Are there any existing ARIN or other legal restrictions against government organizations doing this? -mel beckman
