ULA detected by probe?
by JORDI PALET MARTINEZ 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. --
