 By default, the Tracy client will listen on all network interfaces. If you want to restrict it to only listening on the localhost interface, define the \texttt{TRACY\_ONLY\_LOCALHOST} macro at compile-time, or set the \texttt{TRACY\_ONLY\_LOCALHOST} environment variable to $1$ at runtime.

 By default, the Tracy client will listen on IPv6 interfaces, falling back to IPv4 only if IPv6 is unavailable. If you want to restrict it to only listening on IPv4 interfaces, define the \texttt{TRACY\_ONLY\_IPV4} macro at compile-time, or set the \texttt{TRACY\_ONLY\_IPV4} environment variable to $1$ at runtime.
