About Alpaca

This will highlight URLs on webpages according to their DNS status. If they are being proxied over Cloudflare, then it will highlight them Orange. If they are not being proxied over Cloudflare, then it will highlight them Blue. If there is an NXDOMAIN error, it will highlight the URL red. There are interesting cases where the apex domain is inaccessible, but there is a `www` record, which the browser looks for, so the domain is available. Hovering over a highlighted URL will provide its IPv4 addresses.
