Block websites on Windows 11 with the firewall<\/h2>\n

Windows 11 allows you to block outgoing connections to specific IP addresses using the Windows Firewall, without installing any additional software. This procedure can be used to temporarily restrict access to a service, but it's not the same as permanently blocking a domain: modern websites often use multiple addresses, content delivery networks, IPv6, and shared servers.<\/p>\n<\/section>\n

\n

Direct answer:<\/strong> To block a site with the firewall, you must first find out all its IPv4 and IPv6 addresses and then create a custom exit rule<\/strong> that blocks those IPs. The blocking will work as long as the site continues to use those addresses and the connection doesn't go through a VPN or proxy.<\/p>\n

Do not enter a URL like https:\/\/ejemplo.com\/pagina<\/code> on the firewall:<\/strong> The standard console works with IP addresses, protocols, ports, and programs, not with specific web pages or paths.<\/p>\n<\/div>\n

\n

Important limitation before starting<\/strong><\/p>\n

A single IP address can host multiple websites or services. If you block an address shared by a content delivery network (CDN), pages, images, logins, or applications you didn't intend to block might also fail. Therefore, it's a good idea to note which IP address you added and give the rule a clear name so you can quickly disable it.<\/p>\n<\/div>\n

When is it appropriate to block sites with the firewall?<\/h2>\n

Firewall blocking is useful when you want to prevent the entire computer\u2014or a specific program\u2014from connecting directly to certain remote addresses. For common distractions, family monitoring, or frequently changing domain lists, there are easier-to-maintain methods.<\/p>\n
