+### Headless Services
+For services that are not addressed using a virtual cluster IP, the upstream service must be
+configured using the [DialedDirectly](/docs/connect/config-entries/service-defaults#dialeddirectly) 
+option. 
+
+Individual instance addresses can then be discovered using DNS, and dialed through the transparent proxy.
+When this mode is enabled on the upstream, connect certificates will be presented for mTLS and
+intentions will be enforced at the destination.
+
+Note that when dialing individual instances HTTP routing rules configured with config entries 
+will **not** be considered. The transparent proxy acts as a TCP proxy to the original
+destination IP address.
