Talking NAT64Check at DKNOG in Copenhagen

By Jan ŽoržFormer Operational Engagement Programme Manager

Tomorrow (16 March) from 13:45 – 14:30 CET (UTC+1), at the Danish Network Operators’ Group (DKNOG) in Copenhagen, I’ll talk about our experiments on NAT64 and DNS64 in the Go6lab and also about NAT64Check. Watch live via DKNOG’s live stream page at https://dknog7.dknog.dk/main-room-webstream/.

As many mobile operators are 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 test bed was 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; instructions on how to participate are available on the Go6lab website.

NAT64check allows websites to be checked for consistency over IPv4, IPv6-only, and NAT64, and to compare responsiveness using the different protocols. This allows network and system administrators to easily identify if anything is ‘broken’ and to pinpoint where the problems are occurring, thus allowing any non-IPv6-compatible elements 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.

During the talk I’ll share some insight and discuss issues that I found while testing NAT64/DNS64 technology in real life scenarios and use cases.

If you are at DKNOG, I’m more than happy to chat and discuss all this new technology that makes the Internet such a great place!
