OpenBSD

In order to check that IPv6 works in your PC, run in the shell window or terminal:

ping6 -c5 ::1

If the result is the following (or similar):

$ ping6 -c5 ::1

PING6(56=40+8+8 bytes) ::1 --> ::1

16 bytes from ::1, icmp_seq=0 hlim=64 time=0.168 ms

16 bytes from ::1, icmp_seq=1 hlim=64 time=0.156 ms

16 bytes from ::1, icmp_seq=2 hlim=64 time=0.154 ms

16 bytes from ::1, icmp_seq=3 hlim=64 time=0.237 ms

16 bytes from ::1, icmp_seq=4 hlim=64 time=0.164 ms

--- localhost ping6 statistics ---

5 packets transmitted, 5 packets received, 0% packet loss

round-trip min/avg/max = 0.154/0.176/0.237 ms

It means that IPv6 is installed correctly. Basically you need to be able to read "5 packets received".

However, if the system does not recognize the command introduced (and/or returns any kind of error), follow the instructions in the next section.

IPv6 is installed by default on OpenBSD 2.7 and later.
