Routes supply the **dynamic** information necessary to actually connect to a webserver. This is the specific IP address to attempt (as discovered by a DNS query), the exact proxy server to use (if a [ProxySelector](https://developer.android.com/reference/java/net/ProxySelector.html) is in use), and which version of TLS to negotiate (for HTTPS connections).
