Netstat doesn't show URLs while streaming from Youtube Learning about networks and trying to make sense of `netstat` output. This is the main confusion: When I run the command, there are no known URLs. For example, I'm listening a Youtube streaming and was expecting to see UDP for the streaming. Am I expecting something that is not? Any help? Slice of the output: tcp 0 0 arco:43424 lhr25s15-in-f1.1e:https ESTABLISHED udp 0 0 arco:bootpc ttrouter.lan:bootps ESTABLISHED

Pretty much anything running in a web browser, like youtube, will use only HTTP and HTTP-based protocols like WebSockets. Web browsers forbid non-HTTP connections by websites for security reasons. So you're not usually going to see UDP, except possibly for HTTP-over-QUIC and HTTP 3.

Looking into the network monitor in firefox while while watching a Video on Youtube, I can see a few requests to URLs like < returning webp (video) content. Also in the firefox network monitor, the remote address is displayed as [2a00:1450:4001:1::9]:443 (IPv6).

Using `netstat -tpen` I can see a matching connection:
