In the event of a global DNS outage, accessing websites becomes challenging, but it's possible to visit sites if you know their IP addresses by entering them directly into your browser. However, this method has limitations; websites often use dynamic IP addresses that can change, and accessing a site by IP might not work if it's behind a load balancer or CDN like Cloudflare, which X (formerly Twitter) uses. X's IP addresses have reportedly transitioned from 104.244.40.0/21 to 162.158.0.0/15, but these can be subject to change. Additionally, accessing sites by IP might bypass security checks or lead to certificate issues, making this a temporary workaround rather than a comprehensive solution for internet browsing during DNS outages.
