Does routing depend on the protocol: http or http/2?

Question

Computer networks

Routing over IPv4 and IPv6 is different. Is there a difference in routing depending on the protocol: http or http/2? The http route shown by tracert uses cloudflare. If there are differences, then how to find out the route in http/2?

Answer 1

These are, as it were, fundamentally different levels even in the TCP reference model, not like in the OSI model.
Routing has nothing to do with the application protocol, provided that on the routers someone intentionally does not do DPI and filtering.
It follows that without studying the networks of a particular provider, it is impossible to answer the question unambiguously - maybe they are routing, or maybe they are not routing.

Answer 2

Traffic routing and load balancing in today's networks can be very ornate.
If we consider the same CloudFlare, then there is a lot of things, starting with routing subnets on IP protocols (traditional routing), passing by announcements of these subnets in protocols like BGP (Autonomous System Routing), load balancing through DNS (when the DNS server issues different IP -addresses depending on the load), and ending with balancing at the level of proxy servers and / or applications.
No, ending with balancing containers (docker / kvm), orchestration systems (composer / kubernets), mesh systems (consul.io)
At the same time, each piece does something of its own, trying to give the user access to the resource.
