whoami.akamai.net and public DNS node replies
by Anurag Bhatia 02 Apr '18

02 Apr '18

Hello everyone, Anyone using whoami.akamai.net? I have used it quite a while especially with large anycast players because they tend to have customer facing (anycast) IPs and internet facing unicast IPs to reach to outside world. Thus for say 8.8.8.8 while query may be local to my country (India), I saw that Google was using unicast IP from their Singapore location (as per IPs published here <https://developers.google.com/speed/public-dns/faq> in their FAQ). dig @8.8.8.8 whoami.akamai.net used to give that IP. >From last few weeks, I see results are pretty inconsistent and just makes no sense whatsoever. E.g 5 consecutive queries to 8.8.8.8 asking whoami.akamai.net where Akamai should return me IP of recursor from where query came: dig @8.8.8.8 whoami.akamai.net a +short 103.252.111.59 dig @8.8.8.8 whoami.akamai.net a +short 118.185.164.42 dig @8.8.8.8 whoami.akamai.net a +short 118.185.164.42 dig @8.8.8.8 whoami.akamai.net a +short 14.139.241.214 dig @8.8.8.8 whoami.akamai.net a +short 103.252.111.59 This does not make sense since none of those unicast IPs belongs to Google. I see similar result for any other open DNS service like Cisco's OpenDNS: dig @208.67.222.222 whoami.akamai.net a +short 14.139.240.146 dig @208.67.222.222 whoami.akamai.net a +short 103.252.111.156 dig @208.67.222.222 whoami.akamai.net a +short 14.139.240.157 dig @208.67.222.222 whoami.akamai.net a +short 14.139.240.157 Is anyone aware of any issues in the way whoami.akamai.net works? dig +trace whoami.akamai.net gives me back my unicast IP which is logical considering fact that +trace tends to use local DNS recursor within the machine. This gives an impression that probably TTL is too high and recursors are caching reply which they are not supposed to. But at the same time, I do not see the logic of getting non-Google IPs when querying via 8.8.8.8. ;; QUESTION SECTION: ;whoami.akamai.net. IN A ;; ANSWER SECTION: whoami.akamai.net. 180 IN A 103.252.111.173 I think in past TTL used to be very low to avoid caching for it. Anyone with ideas on what's going on? -- Anurag Bhatia anuragbhatia.com

Network Info Anonymizer
by Spencer Fraint 02 Apr '18

02 Apr '18

Sharing network configuration files (e.g. to get help debugging) can be quite tricky because they contain sensitive information. At the same time, simply removing the sensitive information (e.g. removing or changing all IP addresses) removes important structure from the files, defeating the purpose of sharing. We created Netconan to help. Netconan is an open source Python tool that anonymizes sensitive network information from text files, while preserving important structure. For example: it can take in router configuration files and remove passwords and anonymize IP addresses, while preserving IP address relationships (prefixes/subnets that matched before anonymization will still match after anonymization). Check it out on PyPI (https://pypi.python.org/pypi/netconan/) or GitHub ( https://github.com/intentionet/netconan) and let us know what you think! Thanks, Spencer

ARIN 41 - potential changes to Number Resource Policy (Fwd: [arin-announce] Participate in the Public Policy Process at ARIN 41)
by John Curran 02 Apr '18

02 Apr '18

NANOGers - ARIN operates the number registry according to community-developed policies, but ultimately such policies are shaped by the folks in this community who choose to participate in their development. There are several significant policy proposals that will be considered at ARIN 41, and I’d recommend taking a moment to review them and either comment on our public policy mail list (arin-ppml(a)arin.net<mailto:arin-ppml@arin.net>) or participate in the upcoming meeting (onsite in Miami or remotely, as one prefers) Please see the attached email summarizing potential changes to number resource policy that will be discussed at ARIN 41 two weeks from today. Thanks! /John John Curran President and CEO American Registry for Internet Numbers (ARIN) Begin forwarded message: From: ARIN <info(a)arin.net<mailto:info@arin.net>> Subject: [arin-announce] Participate in the Public Policy Process at ARIN 41 Date: 2 April 2018 at 9:17:06 AM EDT To: <arin-announce(a)arin.net<mailto:arin-announce@arin.net>> We hope you’ve heard about the upcoming ARIN 41 Public Policy and Members Meeting, taking place 15-18 April in Miami, and that you are planning to participate in this important policy discussion forum.

We will also provide an update on the website redesign project that is currently underway and review the results of our most recent customer satisfaction survey. The full ARIN 41 agenda is available at: https://www.arin.net/ARIN41_agenda We hope to see you in Miami, but if you are unable to make it in person, participating online can be equally rewarding. As a registered remote participant, you'll be able to access the live transcript and webcast on the ARIN website throughout the meeting, submit questions and comments alongside in-person attendees, and raise your virtual hand during straw polls. The webcast and live transcript are available to anyone, but if you want to join in the meeting chat room and add your voice to the discussion and participate in straw polls, you must register at: https://www.arin.net/ARIN41_remote Select "Register” and choose “Remote Participant” as your registration type.

xtube.com/ultradns/dynect zone issues
by Feldman, Mark 30 Mar '18

30 Mar '18

If folks from xtube.com/ultradns/dynect are on the list, it appears that there’s a discrepancy in the xtube.com zone being served by the some auths. At least one of the CNAMEs required for resolution is missing from the zone being served by at least some ultra instances. No idea where the breakdown is, but we’ve got customers telling the world that we’re blocking access to porn. I’ll also note that the SOA ttl and ncache are on the large side, so we’re caching those NXDOMAINs for quite a while. Flushing is just playing whack-a-mole at the moment. Also, if folks from any large auths want to provide me with contact info, we’ll happily reach out to you privately/directly should something similar occur in the future .
