IPv6 support

[krital]

Hello, trying to establish a session to an ipV6 address but failing. is IPv6 supported?

[qzhuyan]

do you mean you use ipv6 address or the hostname was resolved to ipv6 addr?

could you specify an example of args inuse?

I mean an ipv6 addr. I used one of your examples from GitHub: ./emqtt_bench pub -c 100 -I 10 -t bench/%i -s 256 -h x:x:x::x:x -p 9000
