Just compiled the 1.0pre2 version (pre1 has missing counter_hash.h file).<br>Apparently the resolver for ipv6 has a problem with resolving local host (do not confuse with localhost) own ipv6 address.<br>I.e. Here the host where iftop is being run has ip6 addres <span>2001:470:b4a7::102 (<a href="http://amagi.gbit6.net" target="_blank">amagi.gbit6.net</a>)<br>

<br>Iftop with dns resolution:<br><a href="http://amagi.intr.gbit6.net" target="_blank">amagi.intr.gbit6.net</a>                                                         &lt;=&gt; <a href="http://cam.intr.gbit6.net" target="_blank">cam.intr.gbit6.net</a><br>


<a href="http://yamato.gbit6.net" target="_blank">yamato.gbit6.net</a>                                                             &lt;=&gt; <a href="http://yamato.gbit6.net" target="_blank">yamato.gbit6.net</a><br>
<a href="http://pool-173-79-27-59.washdc.fios.verizon.net" target="_blank"></a><br>same situation without dns resolution:<br>10.1.0.102                                                                   &lt;=&gt; 10.1.0.101<br>

2001:470:b4a7::102                                                           &lt;=&gt; 2001:470:b4a7::11<br><br>It&#39;s as if it wrongly uses the fqdn resolved for the remote host.<br>Resolving of remote hosts that have ipv6 addr works properly.<br>

<br>A simple mistake I guess?<br><br>Regards<br>Vladimir-M. Obelic<br><br></span>
