/etc/hosts ::1

Damn!
I was reading and using Gentoo. I unplugged my cable modem. I plugged it back in. Nothing! I rebooted, nothing. I shutdown, nothing. I unplugged and plugged it back in again. Nothing. I couldn't open any sites. The connection wouldn't complete.
I didn't know what to do. The first thing I thought of was /etc/hosts. I opened it up, removed the line that has ::1 localhost
which is (::1 gentoo) on mine
It instantly worked. I didn't know, but I knew everything was working perfectly. What is the problem? Can not having this line cause problems? I read it's IPv6, but I didn't find anything good to read about it.
Anyways, now it's working fine again. I hope I did correct this problem. If so, it was definitely easy to guess.

It should not cause any problem..
One way to figure out...try putting it back and check if there are any problems.
It seems more like co-incidence for me.

No, it's still happening. I put it back in the file, and my connection quit working. I deleted it again, and it connected.
I fixed it all by myself.

It was on the second line, but both times it would not work until I deleted it and then it would instantly work. I never used IPv6 USE flags or anything, if you were wondering ...
