Complete the tasks in the next task map in sequential order to accomplish the planning tasks necessary for IPv6 deployment.
| Task | Description | For Instructions | 
|---|---|---|
| 1. Prepare your hardware to support IPv6. | Ensure that your hardware can be upgraded to IPv6. | |
| 2. Get an ISP that supports IPv6. | Ensure that your current ISP supports IPv6. Otherwise, find an ISP who can support IPv6. You can use two ISPs, one ISP for IPv6 and one for ISP IPv4 communications. | 
 | 
| 3. Ensure that your applications are IPv6 ready. | Verify that your applications can run in an IPv6 environment. | |
| 4. Get a site prefix. | Obtain a 48-bit site prefix for your site from your ISP or from the nearest RIR. | |
| 5. Create a subnet addressing plan. | You need to plan the overall IPv6 network topology and addressing scheme before you can configure IPv6 on the various nodes in your network. | |
| 6. Design a plan for tunnel usage. | Determine which routers should run tunnels to other subnets or external networks. | |
| 7. Create an addressing plan for entities on the network. | Your plan for addressing servers, routers, and hosts should be in place before IPv6 configuration. | |
| 8. Develop an IPv6 security policy. | Investigate IP Filter, IP security architecture (IPsec), Internet Key Exchange (IKE), and other Solaris security features as you develop an IPv6 security policy. | |
| 9. (Optional) Set up a DMZ. | For security purposes, you need an addressing plan for the DMZ and its entities before you configure IPv6. | |
| 10. Enable the nodes to support IPv6. | Configure IPv6 on all routers and hosts. | |
| 11. Turn on network services. | Make sure that existing servers can support IPv6. | |
| 12. Update name servers for IPv6 support. | Make sure that DNS, NIS, and LDAP servers are updated with the new IPv6 addresses. |
