Serious Discussion Browser is connecting to random IPs, is it normal?

[Rov123]

Hello,
I am noticing strange connections my PC is making on outbound. For example, I am using the brave browser and I have only YouTube.com opened, and I notice multiple processes of brave is showing up and connecting to multiple IP addresses, one of which is YouTube but the others I have no idea what they are.

As I am monitoring these traffics, my brave browser only has Twitch.tv opened. What are these other connections? 151.101.194.167 is twitch.tv, I don't understand these other ips.
I also tried blocking these on firewall, and it does not work.

Yes, it's normal. Browsers often connect to multiple servers for various reasons like loading ads, tracking user behavior, or fetching data from content delivery networks. If you're concerned, consider using tools to monitor and control outbound connections.

Use a good doh dns server with anti-malware, anti-tracking and adblock capabilities, like nextdns or quad9. Use windows built-in doh service or use yogadns app for system wide doh and disable doh function on individual browsers.

Amazon & Cloudflare CDN (content delivery network - hosting various files), DEFT.com (servers providers), Google, Fastly (internet provider). Nothing unusual.



If you would use a custom DNS, it would translate IPs in logs into readable domains.
