<a href="http://ipv4-ipv6.blogspot.com/" target="_blank">IPNetInfo</a> is a small freeware
 utility that allows you to easily find all available information about 
an IP address. It can fetch you the details like the owner of the IP 
address, the country/state name, IP addresses range, contact information
 (address, phone, fax, and email), and more. Now that the Internet is 
moving towards IPv6 addresses,  the new version of IPNetInfo, you can 
even get the details of IPv6 addresses.

In
 order to use this feature in the app, you have to check the ‘Detect 
IPv6 Addresses’ option in the ‘Choose IP addresses’ window. This option 
is disabled by default when you run the application. After enabling this
 feature, you can type one or more IPv6 addresses in the addresses list 
text-box, and then the result looks like in the image above. 
 
The
 IP address information is retrieved by sending a request to the whois 
server. The program uses multiple Whois servers, so in case one is not 
able to retrieve the information, the app uses the other ones available.

How To Disable IPv6 In Ubuntu 10.04 Lucid Lynx ?

Tukiyooo 1 IPv6, Lynx, Setup IPv6, ubuntu 01:40

<div>
I'm not sure if IPv6 in Ubuntu 10.04 Lucid Lynx is still causing 
issues with the Internet connection being slow and so on, but in case it
 does here's how to disable it.</div>
 <a href="https://www.facebook.com/note.php?note_id=392223309742#" role="button"></a> 
<div>
To check if IPv6 is disabled, run the following command: <pre class=""><code>cat /proc/sys/net/ipv6/conf/all/disable_ipv6</code></pre>
 0 means it's enabled and 1 - disabled. This tweak is thanks to an old comment from <a href="http://l.facebook.com/l.php?u=http%3A%2F%2Fwww.webupd8.org%2F2009%2F11%2Fhow-to-disable-ipv6-in-ubuntu-910.html%23comment-26954313&h=GAQHSEos9&s=1" rel="nofollow" target="_blank">Stonecut</a>
 (this way you don't have to edit the GRUB). Basically, to disable IPv6 
in Ubuntu 10.04 Lucid Lynx, you have to add the following lines to /etc/sysctl.conf: <blockquote>
#disable ipv6 net.ipv6.conf.all.disable_ipv6 = 1 net.ipv6.conf.default.disable_ipv6 = 1 net.ipv6.conf.lo.disable_ipv6 = 1</blockquote>
 To do it from the command line, paste this in a terminal: <pre class=""><code>echo "#disable ipv6" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.all.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.default.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf
echo "net.ipv6.conf.lo.disable_ipv6 = 1" | sudo tee -a /etc/sysctl.conf</code></pre>
 Then reboot and check if IPv6 has been disabled with the command in the beginning of the post. If for some reason IPv6 still shows up as enabled in Ubuntu 10.04 Lucid Lynx, you can use the method described in THIS post. This tweak (and others) will go into Ubuntu 10.04 Start script (I don't know why I didn't think of this before).</div>

Does I have IPv6? What is my IPv6? Why IPv6?

Tukiyooo 1 IPv6, IPv6 Routing 01:31

I think everyone was thought about IPv4 and IPv6 but on internet are tones of articles about IPv6 and IPv4 and you should read more to understand this concept. 
In this tutorial I will try to explain what is with IPv6 in few words. 
 
 
<h2>
How does IPv6 looks like?</h2>
First you should know that ipv6 is different from ipv4. 
IPv4 Example: <code>81.21.211.234</code> 
IPv6 Example: <code>2001:0db8:85a3:0042:1000:8a2e:0370:7334</code> 
<h2>
Does I have IPv6?</h2>
Well, the correctly question is: I’m connected to internet via IPv4 or IPv6? 
Your IP is allocated by your internet provide, so they can give you an IPv4 or IPv6. 
<code>To check what kind of IP you are connected through you can go here</code>: <a href="http://ipv4-ipv6.blogspot.com/2014/07/i-think-everyone-was-thought-about-ipv4.html" rel="nofollow" target="_blank" title="Check IP Address - My IPv6 Address">Check IP Address – IPv4 or IPv6</a> 
<h2>
Why IPv6?</h2>
Because the IPv4 have 32bits of address and can provide maximum 4.3 
billion addresses. So in the whole world this number of addresses has 
reached/will soon reached and we need more IP Addresses. 
IPv6 have 128 bits and support approximately 2128 addresses. 
<h2>
Conclusion</h2>
You know a little but more about your connection and about your IP Addresses.

If you want more you should go to Wikipedia and read more documentation.

IPv6 Mobility

Tukiyooo 0 IPv6, mobile phone, Setup IPv6 01:23

When a host is connected to one link or network, it acquires an IP 
address and all communication happens using that IP address on that 
link. As soon as, the same host changes its physical location, that is,
 moves into some different area / subnet / network / link, its IP 
address changes accordingly and all communication happening on the host 
using old IP address, goes down. 
IPv6 mobility provides a mechanism which equips a host with an 
ability to roam around among different links without losing any 
communication/connection and its IP address. 
Multiple entities are involved in this technology: 
<ul class="list">
<li>Mobile Node: The device which needs IPv6 mobility. </li>
<li>Home Link: This link is configured with the home subnet prefix and this is where the Mobile IPv6 device gets its Home Address.</li>
<li>Home Address: This is the address which Mobile Node 
acquires from Home Link. This is permanent address of Mobile Node. If 
the Mobile Node remains in the same Home Link, the communication among 
various entities happens as usual.</li>
<li>Home Agent: This is a router which acts as registrar for 
Mobile Nodes. Home Agent is connected to Home Link and maintains 
information about all Mobile Nodes, their Home Addresses and their 
present IP addresses.</li>
<li>Foreign Link: Any other Link which is not Mobile Node’s Home Link.</li>
<li>Care-of Address: When a Mobile Node attaches to a Foreign 
Link, it acquires a new IP address of that Foreign Link’s subnet. Home 
Agent maintains the information of both Home Address and Care-of 
Address. Multiple Care-of addresses can be assigned to Mobile Node, but
 at any instance only one Care-of Address has binding with Home Address.</li>
<li>Correspondent Node: Any IPv6 enable device which intends to have communication with Mobile Node.</li>
</ul>
<h2>
Mobility Operation</h2>
When Mobile Node stays in its Home Link, all communications happen on its Home Address. As shown below: 
<figure>
<img caption="Mobile Node in Home Link" src="http://www.tutorialspoint.com/ipv6/images/MN_in_HL.jpg" />
<figcaption align="center">[Image: Mobile Node connected to Home Link]</figcaption>
</figure>When Mobile Node leaves its Home Link and is connected to some 
Foreign Link, the Mobility feature of IPv6 comes into play. After 
connecting to Foreign Link, Mobile Node acquires an IPv6 address from 
Foreign Link. This address is called Care-of Address. Mobile Node 
sends binding request to its Home Agent with the new Care-of Address. 
Home Agent binds Mobile Node’s Home Address with Care-of Address, 
establishing a Tunnel between both. 
Whenever a Correspondent Node tries to establish connection with 
Mobile Node (on its Home Address), the Home Agent intercepts the packet 
and forwards to Mobile Node’s Care-of Address over the Tunnel which was 
already established. 
<figure>
<img caption="Mobile Node in Foreign Link" src="http://www.tutorialspoint.com/ipv6/images/MN_in_FL.jpg" /> 
<figcaption align="center">[Image: Mobile Node connected to Foreign Link]</figcaption>
</figure><h2>
Route Optimization</h2>
 
When a Correspondent Node initiate communication by sending packets 
to Mobile Node on Home Address, these packets are tunneled to Mobile 
Node by Home Agent. In Route Optimization mode, when the Mobile Node 
receives packet from Correspondent Node, it does not forward replies to 
Home Agent. Rather it sends its packet directly to Correspondent Node 
using Home Address as Source Address. This mode is optional and not 
used by default.

IPv6 Subnetting

Tukiyooo 0 IPv6, Setup IPv6, Subnetting 01:21

<a href="http://ipv4-ipv6.blogspot.com/" target="_blank">In IPv4</a>, addresses were created in classes. Classful IPv4 addresses 
clearly defines the bits used for network prefixes and the bits used for
 hosts on that network. To subnet in IPv4 we play with the default 
classful netmask which allows us to borrow hosts bit to be used as 
subnet bits. This results in multiple subnets but less hosts per 
subnet. That is, when we borrow host bit to create a subnet that costs 
us in lesser bit to be used for host addresses. 
IPv6 addresses uses 128 bits to represent an address which includes 
bits to be used for subnetting. Second half of the address (least 
significant 64 bits) is always used for Hosts only. Therefore, there is
 no compromise if we subnet the network. 
<figure>
<img caption="IPv6 Subnetting" src="http://www.tutorialspoint.com/ipv6/images/subnetting.jpg" />
<figcaption align="center">[Image: IPv6 Subnetting]</figcaption>
</figure>16 Bits of subnet is equivalent to IPv4’s Class B Network. Using 
these subnet bits an organization can have more 65 thousands of subnets 
which is by far, more than enough. 
Thus routing prefix is /64 and host portion is 64 bits. We though, 
can further subnet the network beyond 16 bits of Subnet ID, borrowing 
hosts bit but it is recommended that 64 bits should always be used for 
hosts addresses because auto-configuration requires 64 bits. 
IPv6 subnetting works on the same concept as Variable Length Subnet Masking in IPv4.

/48 prefix can be allocated to an organization providing it the 
benefit of having up to /64 subnet prefixes, which is 65535 
sub-networks, each having 264 hosts. A /64 prefix can be assigned to a 
point-to-point connection where there are only two hosts (or IPv6 
enabled devices) on a link.
