Cant ping externally raspberry pi3+

Question

New to Raspberry pi so this may be a rookie problem. I installed Raspbian as per instructions and all seems well, including browsing, compilations etc. I am connected via wifi and ifconfig shows a valid ip address for wlan0.

ping 127.0.0.0 gives:

pi@raspberrypi:~ $ ping 127.0.0.1
PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.
64 bytes from 127.0.0.1: icmp_seq=1 ttl=64 time=0.102 ms
64 bytes from 127.0.0.1: icmp_seq=2 ttl=64 time=0.119 ms

ping google.com gives:

PING google.com(syd09s12-in-x0e.1e100.net (2404:6800:4006:803::200e)) 56 data bytes
^C
--- google.com ping statistics ---
645 packets transmitted, 0 received, 100% packet loss, time 669783ms

So clearly not working. What am I doing wrong? Same result for all external addresses - but Chromium working fine.

Here is the config output is that helps:

try ping -4 google.com - see if it's some ipv6 issue (did not realise telstra issued ipv6 yet) — Jaromanda X, Jan 31 '19 at 03:32
Yes that worked... I will read up some more on ping -4 and get back if I need more explanation — bcperth, Jan 31 '19 at 04:19
Ok just enforcing IP4 .... thank you. I have Telstra NBN which by the way has proven to be fast and reliable over pst 2 years (once the torture of applying and actually getting connected is endured). — bcperth, Jan 31 '19 at 04:22
It's not really a raspberry pi specific issue though, as it turns out, so, like a couple of answers I've posted recently, it makes no sense if the question is "closed" for being off topic - I think some moderators are heavy handed :p — Jaromanda X, Jan 31 '19 at 04:32
Please check your network setup as described in How do I set up networking/WiFi/static IP address?. — Ingo, Jan 31 '19 at 10:46

You may have already done this, but I always disable IPV6 on the Pi (and everywhere else):

edit /etc/sysctl.conf add: net.ipv6.conf.all.disable_ipv6 = 1

sudo sysctl -p or reboot :)
