example of http-wmt-get request with ipv6

[aasraoui]

Looking for an example on how to initiate http-wmt-get request with ipv6 ,
is there an option for this which can be added to the opt list ?

getoptlong.each do |opt, arg|
case opt
when "--help"
puts "show help"
when "--speed"
puts "Speed is " + arg
speed = arg
when "--duration"
puts "Duration is " + arg
duration = arg.to_i
when "--verbose"
verbose = true
when "--url"
puts "Requested URL is " + arg
url = arg

thanks,
AA
