Hello,

I am new to node-red. And new to this forum too! In the links please replace "-" with "." 🙂

For learning purposes I want to try ping a target and show the result on an dashboard 🙂

I use "node-red-node-ping" and hoped to get the Roundtriptime in ms as msg.payload. But I was wrong...

The following targets are "not pingable" and I get "false" as return value:

(IPVx = Automatic or =IPV6)  
www-google-de  
google-de  
localhost  
heise-de

The following URL does work correct:  
(IPVx = Automatic)  
ipv4-google-com

(IPVx = IPV4)  
heise-de

For me it seems that ping to IPV6 targets does not work correct.

My Desktop is a Windows 10 with IPv6 as default.

Please try to reproduce. And If you have a hint for me I would be very thankfull.

Kind Regards  
Rainer

Does the command line `ping` command work with ipv6?

I thought it was necessary to use `ping6` for IPV6 addresses.

Hello Colin,

what do you mean with "ping6"? This is not an windows cmd command nor an node-red task.

Linux = ping6  
Windows = ping -6 [IPV6 address]

@dceejay,

yes I tried IPV6 also and for better reading. I edited the original Forumstext.

@edje, Colin11: ping -6 force the usage of ipv6 but in my environment it is not necessary cause my host use ipv6 as default. ping -6 does work correct 🙂

Which version of node-red, nodejs and node-red-node-ping are you using?  
`node -v` to get nodejs version.

It is working ok for me on Ubuntu, specifying my own ipv6 local address.

Is your system set up to use IPV6?
