OK, why does it believe it may be an IPv6 address? And how to force it to regard it as IPv4? Which command-line option?

% ./atlas ping -h  
NAME:
   atlas ping - ping selected address

USAGE:
   atlas ping [arguments...]

DESCRIPTION:
   send echo/reply to an IP

Anyway, it also fails with an IPv6 address:

% ./atlas ping 2400:cb00:2048:1::6814:55

OK, -h has to be used only before the command name. So, I use the -6 option and it works:

% ./atlas -6 ping  2400:cb00:2048:1::6814:55
2017/11/14 00:19:14 req=&atlas.MeasurementRequest{Definitions:[]atlas.Definition{atlas.Definition{Description:"Ping - 2400:cb00:2048:1::6814:55", Type:"ping", AF:6, Target:"2400:cb00:2048:1::6814:55", GroupID:0, Group:"", InWifiGroup:false, Spread:0, Packets:0, PacketInterval:0, ExtraWait:0, IsOneoff:false, IsPublic:false, ResolveOnProbe:false, Interval:0, Protocol:"", QueryClass:"", QueryType:"", QueryArgument:"", Retry:0, SetCDBit:false, SetDOBit:false, SetNSIDBit:false, SetRDBit:false, UDPPayloadSize:0, UseProbeResolver:false, DestinationOptionSize:0, DontFragment:false, DuplicateTimeout:0, FirstHop:0, HopByHopOptionSize:0, MaxHops:0, Paris:0, ExtendedTiming:false, HeaderBytes:0, Method:"", MoreExtendedTiming:false, Path:"", QueryOptions:"", UserAgent:"", Version:"", Port:0, Size:0, AnonymousIdentity:"", Cert:"", EAP:""}}, Probes:atlas.ProbeSet{struct { Requested int "json:\"requested\""; Type string "json:\"type\""; Value string "json:\"value\""; Tags map[string]string "json:\"tags,omitempty\"" }{Requested:10, Type:"area", Value:"WW", Tags:map[string]string(nil)}}, BillTo:0, IsOneoff:true, SkipDNSCheck:false, Times:0, StartTime:0, StopTime:0}
m: &{[10185594]}
resp: "{\"measurements\":[10185594]}"
d: &{[{Ping - 2400:cb00:2048:1::6814:55 ping 6 2400:cb00:2048:1::6814:55 0  false 0 0 0 0 false false false 0     0 false false false false 0 false 0 false 0 0 0 0 0 false 0  false     0 0   }] [{10 area WW map[]}] 0 true false 0 0 0}
m: &{[10185594]}

But there is still the problem: why atlas, by default, always make the wrong choice?

[keltia]

By default, atlas sends both IPv4 and IPv6 requests and it fails with IPv4 (as expected). This is something I need to revisit (like making -4 & -6 command-dependent).

[keltia]

I believe I fixed this in 7acea93, thanks.

[bortzmeyer]

I confirm it now works.
