Missing servers in DNSMON
by Chris Amin 13 Dec '17

13 Dec '17

Dear colleagues, It was recently brought to our attention that a small number of name servers were not being included in the visualisations on DNSMON. This issue has now been fixed, but you may notice a gap between mid-September and mid-December when visualising large time ranges for the affected servers. Apologies for any confusion or inconvenience caused. The affected zones and nameservers are: hk. - 203.119.87.218 xn--j6w193g. - 203.119.87.218 il. - 128.139.35.5 il. - 194.146.106.122 il. - 2001:67c:1010:31::53 mx. - 2001:13c7:7000::1 pl. - 2001:1a68:0:17::238 pl. - 2001:a10:121:1::156 pl. - 2a00:4120:8000:2::186 Kind regards, Chris Amin RIPE NCC

ULA detected by probe?
by JORDI PALET MARTINEZ 06 Dec '17

06 Dec '17

Hi, I’ve two probes in two networks, with exactly the same config in both routers (which are the same, using LEDE). ULA is NOT configured in the router and no other device in the network can see the ULA. However, one of the probes, shows the TAG “IPv6 ULA” And Addresses fd3f:4830:fd21:0:220:4aff:febf:ffaf/64 2001:…. How is that possible and how to clean up it?

Problem with new Openipmap
by Klaus Darilion 06 Dec '17

06 Dec '17

Hi! I just noticed the new interface of Openipmap. Nice, but unfortunately not as useful as the old one: 1. clicking on the graph does not show the trace 2. it does not show 50 traces as the last one (I need plenty of traceroutes for network optimization, not only 10) 3. there should be a possibillity to mark a location as wrong. E.g. see https://atlas.ripe.net/measurements/10418213/#!openipmap Openipmap display Warsaw as target where all this traces terminate in New York as this IP address is an Anycast IP address and therefore it must no be mapped to a single location. hence, for Anycast IPs there should be feature to mark the IP as Anycast. Then the final target is usually the location of the IP address before. regards Klaus

Effect of "Resolve on Probe"-option
by Tim Wattenberg 04 Dec '17

04 Dec '17

Hi everyone, I think I don’t quite understand the effect of the „Resolve on Probe“ option when creating a measurement. The form says it forces the probe to do DNS resolution, the API reference says that it indicates that a name should be resolved (using DNS) on the probe otherwise it will be resolved on the RIPE Atlas servers. Could someone explain what this means for example if I have a simple measurement for querying the A record of a given domain via the probe’s resolvers? Thanks, Tim

map distinction between "no data yet" and "timeout"
by Ben Clifford 01 Dec '17

01 Dec '17

I was just trying to get a map view for a nameserver that appeared to not be responding to people in some geographical areas. I fired off a measurement across a load of probes and get a map back. In my particular case, the result I'm looking for is whether a response came back from the target server at all. But the map doesn't distinguish between probes that haven't measured yet, and probes that have attempted a measurement but timed out, as far as I can tell. --

Trying to measure Quad9 latency
by Eduardo Duarte 29 Nov '17

29 Nov '17

Hi all, After the recent launch of the Quad9 service I try to discover if it had a best response time them my actual resolver, that is google public DNS. To do this I launch a comparing measurement using atlas that would run during one day to the same address from the probes in my ISP. The address that I was trying has a very high TTL so I was expecting to always hit the cache of the servers and them get a good comparison base. I know that there are other factors involve in server response time but to my home connection I fill that this where enough. When I got the results from the measurement they were not what I expected.... The measurements to Quad9 had high value of REFUSAL. Does any one as a clue why??? The measurement result is available at https://atlas.ripe.net/measurements/10269508 Best regards, -- Eduardo Duarte Gestão e Desenvolvimento de Projetos l Project Development Management *DNS.PT* Rua Latino Coelho, n.º 13, 5.º piso | 1050-132 Lisboa | Portugal Tel: (+351) 211 308 200 Fax: (+351) 211 312 720 dns.pt <http://www.dns.pt> | dnssec.pt <http://www.dnssec.pt> | 3em1.pt <https://www.3em1.pt> | facebook.com/dns.pt <https://www.facebook.com/dns.pt> | pt.linkedin.com/in/dnspt <http://pt.linkedin.com/in/dnspt> Aviso de Confidencialidade/Disclaimer: Este e-mail foi escrito de acordo com o novo acordo ortográfico.
