regretting ipv6!

Ok, i started a fresh install with ipv6 in my use flags, and I am seriously regretting it! In the kernel help it said that ipv6 offered "seamless" backwards compatibility with ipv4, well that's not what I found out! It takes wget like 10 seconds to resolve dns, same thing w/ mozilla firebird, elinks etc. I found out that if I used privoxy for elinks and firebird, I don't have to put up with the resolve times, but can't seem to make it work with wget (very important)

Reading the ipv6 documentation is making my head hurt, and I don't understand it, and I don't want to (for the moment anyway).

What do I need to back out of this thing? recompile kernel and remove everything, and recompile all network aware programs w/o ipv6 support?

I can't seem to find an easy way to solve my dns problems w/o learning about bind, tunneling, subscribing to some kind of tunneling service, etc. etc. if somebody can help me out either way, I'd appreciate it!

I suppose an "emerge -ue world" is the only way to be sure?

you said you enabled suport for ipv6, but you dont have any ipv6 connectivity, im correct ?

Thats like if you unplug your internet connection and then type google.com in the browser.
it tries to resolve the host to ip .. but since there is no connection it just hangs until you get a 404 .

get a tunnel then you see theres no delay .

Hi!

this is an old topic, but here's my experience with ipv6:

I never enabled it myself.... it got enabled in the default profile. So i didn't choose to have it. And i never noticed it, until i had problems recently.

I changed some use variables, and did and "emerge world --newuse" to reflect the changes. After that I could only fetch a file with emerge if i pinged the mirror before. Otherwise it would just get the adress 1.0.0.0, and waited for a timeout.

I search everywhere, until I found some posts in svensk (no, i don't understand it) where I saw the words "wget" and "emerge" and "1.0.0.0" and "dns". I did my math and got to solve it by emerging wget with "-ipv6".

So my question is, why the hell did ipv6 got enabled without me selecting it, and why does wget fail to work with ipv6? No i don't have an ipv6 connection, but it should be backwards compatible, and it isn't.

Problem solved, but i must have lost some hair in the process

I _think_ this is not problem of wget (or any other IPv6 capable app), but problem of badly configured DNS servers. IPv6 resolve is done first and then it should fallback to IPv4, but if DNS server is badly configured, it is trying to resolve IPv6 address for eternity.

But I have configured IPv6 tunnel now and I am happy with it, no slowdown at all. And I am supporting future technology with it! ;-)
