If you’re working in a Cisco network and assigning addresses to your IPv6 network cards, you need to know that just like IPv4 addresses there is a network portion of the address and a host portion of the address.
Both portions are 64-bits long, so the first 64-bits of an IPv6 address is the network address (sometimes referred to as a network ID or network prefix), and the last 64-bits of an IPv6 address is a unique host ID for the specific network ID. The four methods of assigning IPv6 addresses are
- Manual Interface ID Assignment: An address is manually assigned to an interface. This is fairly easy to do with most Cisco devices from the interface configuration with a command likeAs with any manual system, it is easy to assign one address to one interface; but you may not want to manually assign addresses to every device on your network manually.
- EUI-64 Interface ID Assignment: This is similar to a full manual address, but instead of specifying full address, you configure only the network portion of the address, and the remainder of the address is derived from the interface’s Media Access Control (MAC) address. When configuring this from the interface prompt, the command looks like this:The MAC address on your network interface is a 48-bit number and may sometimes be referenced as MAC-48 to denote the length. Because the MAC address is a unique identifier, it can also be referred to as an Extended Unique Identifier (EUI) of 48-bits or EUI-48. MAC refers to a network interface identifier, whereas EUI-48 could be assigned to other devices.The MAC address on your network interface is a 48-bit number and may sometimes be re When designing IPv6, the designers wanted to have unique identifiers that were larger than the current EUI-48, so they lengthened the identifier to 64-bit and created the EUI-64 identifier. So an EUI-64 is simply a globally unique identifier.This configuration makes address assignment much easier because all devices on the same data link share the same network ID, and all you need to have automatically assigned is the host ID, which is guaranteed unique because it is based on the already globally unique MAC address.
- Stateless Auto-Configuration: This is by far the easiest way to configure an IP address on an interface, allowing full automatic configuration. This configuration mode was created to allow all devices on the same data link to automatically configure themselves, reducing administrative overhead for the network administrators. In addition to full auto-configuration, Stateless Auto-Configuration sends a request for a router advertisement(RA), which is used by the client as a 64-bit network ID prefix to the client’s IP address.The MAC address on your network interface is a 48-bit number and may sometimes be re This means that if you have configured your routers with their 64-bit network IDs, your network devices use those network IDs; otherwise, all your network IDs for your internal network are assigned automatically. The 64-bit network ID could be a global or private address, but the remaining 64 bits of the address are chosen automatically by the client.
- DHCPv6 (Stateful): Dynamic Host Configuration Protocol (DHCP) servers that have the appropriate extensions installed for IPv6 can process DHCP address requests. This process for handing out addresses is similar to IPv4; the server is configured with an address pool to hand out, and it randomly fills the address requests from this pool. This process allows for complete control over the assigned client IP address, as well as being able to view the list of assigned addresses.The MAC address on your network interface is a 48-bit number and may sometimes be re In DHCPv6, the client first checks for a router advertisement; and if there is, the client is allowed to use DHCP. If there is no router or the router allows for DCHP, the client sends a multicast request to all DHCP agents on the network; if there are no router advertisements or DHCP responses, the client uses the local-link address.

To configure IPv6 on a Cisco routers, you need to do two things: enable IPv6 routing on a Cisco router using the ipv6 unicast-routing global configuration command. This command globally enables IPv6 and must be the first command executed on the router.
I'm using
Yosemite 10.10.3
Going to
[http://test-ipv6.com/][1]
shows me that 'No IPv6 address detected
'- There are times when a user will need to to manually set an IP address in Mac OS X to one which will be compatible with a joined network, either wi-fi or ethernet. Here will cover how to change a Mac IP address to a manual setting, and also how to pick an IP address which will not be conflicting.
- Do you want to get started with IPv6 but don’t know how to configure it on your Apple Mac? This tutorial for Mac OS X users running Mac OS X v10.6.7 or later will help you get up and running.
- With IPv6 you always have a link-local address (those that usually start with fe80:, although all addresses in the range fe80:0000:0000:0000:0000:0000:0000:0000 - febf:ffff:ffff:ffff:ffff:ffff:ffff:ffff are link-local). The address you configure in the Preferences pane should show up on the interface.
Right now its on '
Automatically
'If I change it to '
Manual
' - what should I write there? what IPv6 address and Prefix?+++UPDATE+++
Thanks to @Ramhound I check my ISP and I changed some settings here:
And I get this:
![Mac Mac](/uploads/1/2/4/6/124629259/580680967.png)
So it looks like I have IPv6 now, but still getting message '
No IPv6 address detected
' on this site http://test-ipv6.com/+++UPDATE2+++

You may need to do a manual configuration.
- Choose System Preferences from the Apple menu ().
- Click the Network icon in the System Preferences window.
- Choose the network service you want to use with IPv6, such as Ethernet or AirPort.
- Click Advanced, then click TCP/IP.
- Choose 'Manually' from the Configure IPv6 pop-up menu.

enter your IPv6 address, router address, and prefix length,If you don't know these, contact your ISP
