Along this journey from your house for your internet issuer to Spotify.com, you, with request facts, will “hop” alon”sid” exceptional routers. Each router will observe where the asked records have to be attained and determine the fastest pathway.
After going through various routers, an agreed-upon connection between your home internet, iPhone, and Spotify can be mounted. As you can see in the image below, I even used a trace path service from the Australian-primarily based enterprise Telstra to Spotify, showing 16 routers along the journey.
