@TawfiqAbubaker Thanks for working on this! 🙏

There are more examples which need this update, please take a look at the CI error https://github.com/aya-rs/book/actions/runs/5314814694/jobs/9622564529?pr=118

I just added another commit, I think it needs you to run the build to see if it's working? I'm not familiar with the build system you have on here. Let me know if it's not working or if I need to add something else

I believe the current failures are caused by the presence of these Cargo.lock files: https://github.com/search?q=repo%3Aaya-rs%2Fbook%20cargo.lock&type=code

We should probably remove them both

Looks like some instances of :ipv6 need to be updated as well.
