Help me understanding ipv6
I refered to some wiki on the web but I still cant catch up..
can anyone simplified this for me?
2604:180::53ac:80e6/128 - ipv6 from HOST 1
2a00:1ca8:37::470b:6e5e/128 - ipv6 from HOST 2
Im trying to follow this guide >> tomsalmon.eu/2013/04/openvpn-ipv6-with-tun-device/
but how can I transform my ipv6 to
2001:412:abcd::/48 or 2001:412:abcd:2::/64
I am totally lost in understanding this..
and why ipv6 from HOST 1 are shorter than HOST 2 ??
Comments
First you cant, because you only have a /128
not a /64
and 2ndo, is not shorter, the prefix lenght they give you, is the same, just maybe host 1 give you ip from a /48 and host 2 from a /64
the "37" there from host 2 is "00" from host 1
I don't understand this part. What are you trying to do?
Transform to? Do you have assigned /48 or /64 subnet at all? If you see only /128 (individual IPv6 addresses) assigned by host this means that you don't have bigger (eg. /48 or /64) subnet available.
It's not. Each IPv6 address have eight segments. Double colons (::) replace a series of zeros.
2604:180::53ac:80e6/128 is the same as:
2604:180:0:0:0:0:53ac:80e6/128 or:
2604:180:0000:0000:0000:0000:53ac:80e6/128
2a00:1ca8:37::470b:6e5e/128 is the same as:
2a00:1ca8:37:0:0:0:470b:6e5e/128 or:
2a00:1ca8:37:0000:0000:0000:470b:6e5e/128
then, If I am following THIS guide, I have to use 2604:180::53ac:80e6/128 instead /64 ??
is this meaning my ipv6 are /128, not /64 ??
I got the ip by doing ifconfig command
here I make it clear.. Im trying to follow the guide in the link I provided before.. but, on the start of the page, he used 2001:412:abcd::/48 for local ip and 2001:412:abcd:2::/64 for tunnel ip.. how can I transform my ip 2604:180::53ac:80e6/128 so I can follow his guide?
I can't help you with that. I never set up IPv6 OpenVPN. Maybe @rm_ can help. In case you try to do that with OpenVZ vps you may have hard time with this tutorial.
Most likely, yes. OpenVZ vps providers usually assign few individual /128 addresses. You have bigger chances to get some decent subnet from Xen or KVM vps providers - but ask first.
oh.. clear for me.. waiting for someone that can help me understanding ipv6 that need to be used in openvpn..
thanks @Spirit

Posted by you, I guess people have responded you there.
hey, you said I got /128.. but then, you said I got /48 and /64 on both of them.. dizzy
you have a single ip, not a range
/128 is just 1 ip
yah, Im asking for tutorial on the thread.. but now I got one..but I need more details on ipv6.. If I can, I would delete the other thread since this thread got more replies
oh.. now it make sense.. I understand it now.. thank you
Which, I am afraid, won't work for you. Not at OpenVZ container with individual /128 address.
yah, all tutorial on the netonly for blocks of ipv6..
I want to doing snat to the ipv6 like I did on ipv4. but as far as I know, ipv6 cant be snat.. I found a guide on the web >> atoomnet.net/howto-ipv6-nat-in-centos-6/ got a way to snat ipv6. but it requires higher kernel. Im using openvz vps that cant be upgraded on my own..
can kvm vps be upgraded?? or only dedi can be upgraded?
Hello, you can check aswell an IPv6 calculator like www.ipv6calculator.net
Please stop bumping every old thread you can find.
he need to get to the amount of posts to post an offer :P
