Cant ping 8.8.8.8 get "Destination Host Unreachable"

[ManicalEngineer]

Thanks in advance,

I can ping google.com and get a response, however when I ping 8.8.8.8 i get "Destination Host Unreachable"

I'm not even sure where to start. I have another pi that works fine on the same network.

Anyone have any advice?

Thanks,

Sean

I'm not even sure where to start.

Start by providing some basic information to give volunteer helpers a chance to assist...

What model of RPi?

What Operating System?

What mode of network connection - WiFi or cabled?

Any information about the local network. At home, as part of a domestic broadband Internet service, or something in an office/business or school/college/Uni?

A recent problem, or something that has never worked?

Any changes you have made to a 'standard' operating system installation?

[ManicalEngineer]

Model: Raspberry Pi B+
OS: Raspbian GNU/Linux
Connected Via Wifi
Home Network, Wifi router connected to cable modem
Recent problem, previously ran as an in-home web sever for a django site
No changes to the standard system

Thanks!

I'll assume it's a 2018 3B+ not a 2014 B+.

Can you ping bbc.co.uk and ping 151.101.192.81?
Can you ping 8.8.4.4?
Does https://google.com/ work in a web browser?

Have you activated any firewall?

[ManicalEngineer]

Actually is it a 2014 B+ you'd think if I'd been buying pis this long I'd have a clue right? lol

I can ping bbc.co.uk but not 151.101.192.81
I cannot ping 8.8.4.4
I can browse to google.com

No firewall

[DougieLawson]

That makes no sense whatsoever. Is your network exclusively IPv6?

Can you post the full output of the ping bbc.co.uk please. It might give a clue.

What I get is:

It looks like Doug was right. You're only using IPv6, so pinging an IPv4 address isn't going to work.
