Aria2: Parallel IPv6 and IPv4 downloading

[Manouchehri]

At the moment, downloading with both IPv6 and IPv4 doesn't seem to work well, since just the A record is used on every interface (which doesn't work for the IPv6 only interfaces).

I also have that problem.
But when I download with a direct IPv6 address it works great.

ftp://speedtest6.tele2.net/100MB.zip doesn't work.

ftp://[2a00:800:1010::1]/100MB.zip works great

I'm unable to use aria2 on an IPv6 only network due to that bug.
