NAT64 Experiments and NAT64Check Tool

Session description:

As many mobile operators were moving to IPv6 only, which is incompatible with IPv4 on the wire, it’s necessary to employ transition mechanisms such as 464XLAT or NAT64. The Go6lab NAT64/DNS64 testbed was therefore established so that operators, service providers, and hardware and software vendors can see how their solutions work in these environments. This has already generated significant interest, and instructions on how to participate are available on the Go6lab website.

When using NAT64 there are many things that need to be checked to ensure they work correctly. NAT64check has therefore been developed to allow websites to be checked for consistency over IPv4, IPv6-only and NAT64, as well to compare responsiveness using the different protocols. This allows network and system administrators to easily identify anything is ‘broken’ and to pinpoint where the problems are occurring, thus allowing any non-IPv6 compatible elements on the website to be fixed. For example, even if a web server is not running IPv6 (why not?), hard-coded IPv4 addresses can cause NAT64 to fail.

Jan Zorz will give insight and discuss some issues that he found while testing NAT64/DNS64 technology in real life scenarios and use-cases.
