I'll note that many websites do NOT support this: https://duckduckgo.com./ https://duckduckgo.com./ - blank page https://www.google.com./ https://www.google.com./ - 301 redirect to non-trailing-dot https://www.amazon.com./ https://www.amazon.com./ - works But even "works" means that the page makes lots of requests to other subdomains etc which do not have the trailing dot, so are still vulnerable for DNS hijack if you have search domains set on your system. So while using domains with a trailing dot is a strongly good idea for calling APIs, etc. it is not a practical solution for the end user with a web browser.
