Description Robert Scheck 2005-02-11 15:06:10 UTC 
Description of problem:
Have no IPv6 device, tunnel etc.:
> host whois.6bone.net
whois.6bone.net has address 192.103.19.12
whois.6bone.net has IPv6 address 2001:490:f000:1300::c
>
> mtr -c 5 -r whois.6bone.net
HOST: tux.local.network      Loss%   Snt   Last   Avg  Best  Wrst StDev
>

Version-Release number of selected component (if applicable):
mtr-0.69-2

How reproducible:
Everytime after disabling IPv6 support.
  
Actual results:
MTR tries to ping a IPv6 address even if no -6 is specified and no IPv6
device is available.

Expected results:
MTR should try IPv4 rather IPv6 if -6 isn't given.

Works nicely here:

[root@hamburg ~]# host whois.6bone.net
whois.6bone.net has address 192.103.19.12
whois.6bone.net has IPv6 address 2001:490:f000:1300::c
[root@hamburg ~]# mtr -c 5 -r whois.6bone.net
