Does anybody know some method how to measure both types of traffic on the dual stack interface? It would be interesting for me to advertise AAAA of our public webserver into the DNS and then observe, how the IPv6 traffic is increasing and possibly later IPv4 is decreasing on that machine. I was trying to get the separate IPv6 and IPv4 info from interface on Linux (Debian) machine via ifconfig command and on CISCO router via SNMP, but it seems to me, that there are not Gauges for IP version separated values. The only thing I can measure now is traffic flow through our IPv6 Tunnel (on CISCO router). Thanks in advance for any info Jakub Serych
