Q. Is there a way to display only IPv6 traffic in InterMapper Flows?

A. There's no direct function to only view the IPv6 flows, but a simple filter can be constructed. To only search for IPv6 flows, enter this in the Hosts filter box:

::1/0


The ::1 is the localhost address in IPv6. It is short for 0:0:0:0:0:0:0:1.
The /0 is basically the IPv6 CIDR block, meaning that all 128 bits are 'don't care'. So in a sense, it is the same as these addresses:

::0/0
::c0:ff:ee/0
