Does Blogspot provide specific nameservers that users need to enter at their domain registrar?

No, Blogspot does not provide specific nameservers that users need to enter at their domain registrar. Unlike some hosting providers that require you to change your domain's nameservers to theirs, Blogspot (being a Google service) operates differently. Instead, you keep your existing nameservers (usually those of your domain registrar) and simply add or modify CNAME and A records within your domain's DNS settings to point your custom domain to Google's shared infrastructure for Blogspot. Google then handles the routing internally from `ghs.google.com` to your specific blog.
