Re: Disabling ipv6

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I also would like to try using IPv6 periodically.

It's only recently, my local router had a firmware upgrade to support IPv6.
The default setting for IPv6 within the router is still "Disabled".
When I change this setting to "Auto Detect", 
the router gets an IPv6 address from the ISP.
The router indicates the connection type, through the ISP is 6to4 Tunnel.

I need to reboot any device, which uses the router, to get IPv6 addresses.
I have to check these devices to see if IPv6 is enabled on them.

The last time I did this, I found IPv6 had a little more latency than IPv4.
After deciding the ISP and router were still "not there", I disabled IPv6.
I haven't tried this recently, but this thread makes me want to try again.
Hopefully the router has better firmware and the ISP IPv6 support has improved.

In answer to a question how does one tell if the ISP supports IPv6,
I can only suggest turn IPv6 on and see if one gets a DHCP IPv6 address.
If one gets an IPv6 address, one must still test things.
One could possibly disable IPv4 to insure one is actually use IPv6.

As a matter of interest, how can one tell if an ISP supports IPv6?
This is slightly OT, but I often think I'd like to try using ipv6,
but when I ask I'm given a purely theoretical reply,
which I don't understand, usually involving SixXS.
Are there simple instructions anywhere, just listing the commands to use,
and not telling me how many people in China are using the internet.
