Common Problems When Deploying IPv6
This section describes issues and problems that you might encounter while deploying IPv6 at your site.
IPv4 Router Cannot Be Upgraded to IPv6
If your existing equipment cannot be upgraded, you might have to purchase IPv6-ready equipment. Check the manufacturers' documentation for any equipment-specific procedures you might have to perform to support IPv6.
Certain IPv4 routers cannot be upgraded for IPv6 support. If this situation applies to your topology, physically wire an IPv6 router next to the IPv4 router. Then, you can tunnel from the IPv6 router over the IPv4 router.
Problems After Upgrading Services to IPv6
You might encounter the following situations when preparing services for IPv6 support:
• Certain applications, even after they are ported to IPv6, do not turn on IPv6 support by default. You might have to configure these applications to turn on IPv6.
• A server that runs multiple services, some of which are IPv4 only, and others that are both IPv4 and IPv6, can experience problems. Some clients might need to use both types of services, which leads to confusion on the server side.

Current ISP Does Not Support IPv6
If you want to deploy IPv6 but your current ISP does not offer IPv6 addressing, consider the following alternatives to changing ISPs:
• Hire an ISP to provide a second line for IPv6 communications from your site. This solution is expensive.
• Get a virtual ISP. A virtual ISP provides your site with IPv6 connectivity but no link. Instead, you create a tunnel from your site, over your IPv4 ISP, to the virtual ISP.
• Use a 6to4 tunnel over your ISP to other IPv6 sites. For an address, use the registered IPv4 address of the 6to4 router as the public topology part of the IPv6 address
