Hello,

When i tried running a scan of an IPv6 address i got the following error every time

panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x8 pc=0x702474]

goroutine 34 [running]:

I added a fix with eb56e98c8da33b16706662a53ee229ca82a370bc so the error message is more clear.

If you want to scan an IPv6 address, please use the proper format, for example: webanalyze -host "http://[2a02:2e0:3fe:1001:302::]"
