ping to IPv6 host example
Type the command as follows:
$ ping6 localhost
$ ping6 host.domain.com
$ ping6 IPv6-address
$ ping6 2001:4860:b002::68
The best way is to ping global website such as ipv6.google.com, enter:
$ ping6 ipv6.google.com
Sample outputs:
ping6 ipv6.google.com PING ipv6.google.com(2001:4860:b002::68) 56 data bytes 64 bytes from 2001:4860:b002::68: icmp_seq=0 ttl=59 time=58.4 ms 64 bytes from 2001:4860:b002::68: icmp_seq=1 ttl=59 time=56.4 ms 64 bytes from 2001:4860:b002::68: icmp_seq=2 ttl=59 time=62.1 ms 64 bytes from 2001:4860:b002::68: icmp_seq=3 ttl=59 time=56.8 ms 64 bytes from 2001:4860:b002::68: icmp_seq=4 ttl=59 time=56.5 ms 64 bytes from 2001:4860:b002::68: icmp_seq=5 ttl=59 time=59.5 ms --- ipv6.google.com ping statistics --- 6 packets transmitted, 6 received, 0% packet loss, time 5002ms rtt min/avg/max/mdev = 56.443/58.329/62.150/2.045 ms, pipe 2
ping by an IPv6 IP address
First, use the host command to find out IPv6 address for www.cyberciti.biz, type:
$ host -t AAAA www.cyberciti.biz
Sample outputs:
www.cyberciti.biz has IPv6 address 2607:f0d0:1002:51::4
Type the following command:
$ ping6 2607:f0d0:1002:51::4
Sample outputs:
PING 2607:f0d0:1002:51::4(2607:f0d0:1002:51::4) 56 data bytes 64 bytes from 2607:f0d0:1002:51::4: icmp_seq=1 ttl=64 time=0.056 ms 64 bytes from 2607:f0d0:1002:51::4: icmp_seq=2 ttl=64 time=0.027 ms 64 bytes from 2607:f0d0:1002:51::4: icmp_seq=3 ttl=64 time=0.021 ms 64 bytes from 2607:f0d0:1002:51::4: icmp_seq=4 ttl=64 time=0.023 ms ^C --- 2607:f0d0:1002:51::4 ping statistics --- 4 packets transmitted, 4 received, 0% packet loss, time 3831ms rtt min/avg/max/mdev = 0.021/0.031/0.056/0.015 ms
One more example:
$ host -t AAAA www.google.com
$ ping6 -c 4 2607:f8b0:4000:805::1010
Sample outputs:

How do I confirm that IPv6 is configured or working on my Linux based system?
Type the following commands (see How To Test Linux Operating System for IPv6 Networking Support for more info):
[ -f /proc/net/if_inet6 ] && echo 'IPv6 ready system!' || echo 'No IPv6 support found! Compile the kernel!!'
And
lsmod | grep -qw ipv6 && echo "IPv6 kernel driver loaded and configured." || echo "IPv6 not configured and/or driver loaded on the system."
Sample outputs:

A note about MS-Windows XP/7/8/server users
You can test an IPv6 connection by using the ping command. At a command prompt, type:
ping -6 www.cyberciti.biz
ping -6 2607:f0d0:1002:51::4

$ man 8 ping6

ping ipv6 between windows and linux
ping ipv6 in windows
Try pinging the loopback 127.0.0.1 and see what you get.
or try ::1 which is correct for IPv6.
I couldn’t get PING6 to work… but noticed that PING uses PING -6 #### to work…
ping6 is for linux, ping -6 is for windows
Good and many many thanks buddy really nice great post and keep up the good work
On Windoze you will use ‘PING -6’, on -NIX you will use ‘PING6’.
I got:
$ ping6 ipv6.google.com
connect: Network is unreachable
Does it means my network didn’t give me an ipv6 address?
On http://ipv6test.google.com/ I got:
“No problems detected.
You don’t have IPv6, but you shouldn’t have problems on websites that add IPv6 support.”
Note the word ‘add’ in this misleading answer. It says, that your software is ready, but your ISP is not. But your computer will know how to ask for the IPv4-version of the site.
thank you .. by now I already changed ISP.. but I admit nothing to do with IPv6.. not yet on top of my priorities ;-)
On a mac, if you get “ping6: UDP connect: No route to host”
Then, add your interface as an argument “ping6 -I en2 fe80::aa……..”
good share.. thanks
How can I configure my IPv6 address on the file: /etc/sysconfig/network/ifcfg-lo on openSuse 13.2?
I tryed:
IPADDR_0=’2804:CC4::4/128′
IPADDR_0=’IPV6′
but it´s not working.
When I add the address by command: ip -6 address add 2804:CC4::4/128 dev lo
It works.
Could ypu help me?
i ll try it.
I cannot ping without mentioning the interface
$ ping6 fe80::20c:29ff:fe4e:691c
connect: Invalid argument
$ ping6 fe80::20c:29ff:fe4e:691c%eth1
PING fe80::20c:29ff:fe4e:691c%eth1(fe80::20c:29ff:fe4e:691c) 56 data bytes
64 bytes from fe80::20c:29ff:fe4e:691c: icmp_seq=1 ttl=64 time=0.031 ms
64 bytes from fe80::20c:29ff:fe4e:691c: icmp_seq=2 ttl=64 time=0.036 ms
Perhaps you have a single interface in your box?
