-4 is using ICMPv6

[exmatrikulator]

If you provide the '-4' flag the IPv4 address will be shown.
But if you look into the packages IPv6 package are send.

Can you be more clear? What OS are you using, and what specific command are you running?

I'm using Manjaro.

• make sure you have a internet connection with IPv4 and IPv6 working.
• start tcpdump -i <interface> -n 'icmp or icmp6' in the background
• watch the difference between gping google.com and gping google.com -4

gping shows different IPs(4/6), but tcpdump shows only IPv6.

Thank you for this information, it is really helpful. I’ll take a look.

Could you also give me the version of ping you’re using? That should be all I need to fix this.

gping --version

gping 1.17.3
