socket passing (i.e. sockets passed in via standard input and
output, using StandardInput=socket in the
service file).

+ All network sockets allocated through .socket units are allocated in the host's network
+ namespace (see network_namespaces7). This
+ does not mean however that the service activated by a configured socket unit has to be part of the host's network
+ namespace as well. It is supported and even good practice to run services in their own network namespace (for
+ example through PrivateNetwork=, see
+ systemd.exec5), receiving only
+ the sockets configured through socket-activation from the host's namespace. In such a set-up communication within
+ the host's network namespace is only permitted through the activation sockets passed in while all sockets allocated
+ from the service code itself will be associated with the service's own namespace, and thus possibly subject to a a
+ much more restrictive configuration.
