Microsoft Geo-IP Admin needed
by Fredy Kuenzler 30 Oct '15

30 Oct '15

Can anyone point me to a Microsoft Geo-IP admin? Their Geo-IP for live.com/outlook.com seems to be rather outdated. We get complaints for 85.195.208.0/20 and 85.195.224.0/19, pointing to Antarctic instead of Switzerland. Any commercial Geo-IP shows correct information, but Office product activation fails. Twitter thread: https://twitter.com/fiber7_ch/status/630880605971025920 Offlist response is fine. Thanks. -- Fredy Kuenzler --------------------- Fiber7.

Satellites and submarine cables
by Sean Donelan 30 Oct '15

30 Oct '15

Since the weekend's list problems seem to have died down. How about some infrastructure news. http://spacenews.com/from-russia-some-unofficial-assurance-about-lurking-lu… >From Russia, Unofficial Assurance about Intent of Lurking Luch Satellite http://www.nytimes.com/2015/10/26/world/europe/russian-presence-near-unders… Russian Ships Near Data Cables Are Too Close for U.S. Comfort This seems to be a case of "I know you can see me, and I can see you." Its not new. Multiple countries have demostrated submarine and satellite capabilities over the decades ... more submarines than satellites. But generally everyone has more to lose than gain. What is different is the increasingly public rhetoric. Occasional satellites or submarine cable disruptions haven't had long term impact on the US mainland due to US connectivity options. Carriers serving the US mainland regularly have outages and repair submarine cable and satellite problems. But countries with less connectivity options could get pushed around more, along the lines of "Make him an offer he can't refuse." Some of the public rhetoric may be for allies.

Level 3 issues in Chicago
by Randy Carpenter 30 Oct '15

30 Oct '15

A network that we manage is having trouble getting to several sites. The common point of failure appears to be Level 3 in Chicago. Connections work fine from our direct upstream, so it appears that Level 3 is not allowing traffic sourced from the net block in question. Can someone from Level 3 ping me off list? thanks, -Randy

NANOG list attack
by Larry Blunk 29 Oct '15

29 Oct '15

All, Just wanted to apologize for the attack over the weekend. The posts came from a email address that was subscribed to the list, so it was not subjected to moderation. While a filter was added to block further posts (which were made in a short time window), there were existing message queues that were not cleared in a timely basis. As Job Snijders (a fellow Communications Committee member) noted in an earlier post, we will be implementing some additional protection mechanisms to prevent this style of incident from happening again. We will be more aggressively moderating posts from addresses who have not posted recently, in addition to other filtering mechanisms. Regards, Larry Blunk NANOG Communications Committee Admins(a)nanog.org

configuration sanity check
by marcel.duregards＠yahoo.fr 29 Oct '15

29 Oct '15

Hi Nanogers, Any recommendation about a software which check the live config of cisco/juniper devices against some templates ? The goal is to have a template about different function device, like: - CORE device must have this bloc and this clock - PE device must have at least that and that - CPE must have this and that - Distrib switch block 1 and block2 - etc... And the software run once every day to check which device do not comply with those rules and generate an alert. Thank, - Marcel

[CenturyLink][Proto UDP] Blockage of UDP Outbound from Source Port 53
by Jason Hellenthal 29 Oct '15

29 Oct '15

Could a CenturyLink network admin/engineer contact me off list. We have multiple locations receiving DNS queries over UDP where we see the connections making into our server and back out to our CenturyLink edge routers but never completes back to the connecting client at multiple locations. Connections Failing From Digital Ocean NY, Time Warner WI, Rackspace DFW TX (Hartford CT)# dig +short +novc @208.46.135.X domain.com A (Cleveland OH)# dig +short +novc @65.112.236.X domain.com A Connections from Chicago Rackspace to the above locations work as expected. CenturyLink Orlando FL to Hartford CT or Cleveland OH, CenturyLink circuits work as expected. Contact off list for domain and ip information used above. Thanks -- Jason Hellenthal JJH48-ARIN

DDoS mitigation for ISPs
by Mike 29 Oct '15

29 Oct '15

Hello, Is there any DDoS mitigation service provider that can scrub traffic for an ISP network? I have an ASN and BGP and my own netblocks, and I have a 1gbps pipe. I was thinking the scenario would be during attack, we could bring up a tunnel and run bgp over it and advertise some portion of our ip space thru it. I realise getting it setup while attack is taking place would be a little hard and that we likely could expect at least some down time. What we have seen so far has been reflection attacks (dns and ssdp) and we have been able to do rate limiting on these and other protocols to sane values. This has worked well, although the primary risk is once the traffic flow exceeds the link capacity such limiting won't have any net effect. But if we could farm this out during times of trouble to a mitigation services provider, they could advertise our block(s) and rate limit and scrub for us and send us the result, it would be a far better than what we have now (which is effectively nothing). I asked cloudflare this and they stated they are focused on web traffic. My upstream can't help me, doesn't support RTBH and won't install filters anyways unless it's impacting THEIR network. Just wondering if anyone has any other ideas (short of ditching my provider, which I also can't do due at this time due to lack of competitive choice). Mike-

A long time ago, in a place far, far away, the PTB determined that we should change from a three-team, three-8-hour shifts, 5 days a week ("days", "evenings", and "nights" (aka "graves" or "graveyard") for 7 x 24 coverage, to a four-team, 12 1/2 hour day 3 day week (and you know, I have forgotten how we covered the 7th day!). For the 2nd-level managers like me, the reaction was "Wow! I will only have to work 12-18 hours three days a week! -- sed quis custodiet ipsos custodes? (Juvenal)

speedtest vs geo-coding IP info
by lorell＠hathcock.org 28 Oct '15

28 Oct '15

Legions of NANOG: Here's an interesting problem. My customers are running speedtests from Ookla's speedtest.net site. The default site is in Kansas and not in Texas where we receive our internet connection. Questions: 1. How do I go about viewing the geo-coded data that accompanies my IP addresses? This is obviously a database that is kept for geo-coding purposes. The whois info for the block in question traces back to a superblock formerly owned by PSINet, Inc and has a Washington, DC address. I conclude that the geo-coding used by speedtest.net is not from the whois database. 2. If I pestered my carrier to SWIP the IP address block to me (as they should have?) would that help me solve my problem? 3. Is there anything else I need to be thinking of that would help me have better control of my geo-coding info? Are there third-party self sign up/volunteer database which house geo-coding info? Thanks in advance!
