# Domains now include their \`www\` counterpart

Adding a domain to a project will now also suggest adding its `www` counterpart. This ensures visitors can always access your site, regardless of whether they type `www` when entering the domain, or not.

Using a `www` domain guarantees that the [Vercel Edge Network](https://vercel.com/blog/new-edge-dev-infrastructure#our-new-edge-infrastructure) can reliably and securely route incoming traffic as quickly as possible, so redirecting non-`www` to the `www` domain is recommended. Redirecting the other way works too if you prefer a cleaner URL address.

Existing domains are not affected by this change, but we recommend ensuring that your project already has a `www` redirect in place.
