module http/https, inccorrect 'Host' HTTP header when using IPv6 (-6)

[sltrash]

Hello,

When enabling IPv6 cracking with the http/https module, the 'Host' HTTP header sent is 'Host: a:b.c:d' instead of 'Host: servername' as it is with IPv4:

ncrack slt01.hqr.fi:80 -m http,path=/ --user test --pass test

results in the following first request:

GET / HTTP/1.1
Host: slt01.hqr.fi

and with IPv6:
ncrack -6 slt01.hqr.fi:80 -m http,path=/ --user test --pass test

results in the following first request

GET / HTTP/1.1
Host: 2001:bc8:3d1d:1ab0::bee

Obviously this prevents ncrack from working correctly on Virtual Hosts! :-(

Is it something easily fixable?

Thanks in advance!
