`netstat` allows you to easily view which TCP ports are in use and which are free to use.
```{r results = 'hide', warning=FALSE, message=FALSE}
# install.packages("netstat")
library(netstat)
```
### See which TCP ports are currently in use with `ports_in_use()`
```{r}
ports_in_use()
```
### Find a free TCP port using `free_port()`
```{r}
free_port()
```
- `free_port()` returns an available TCP port from Internet Assigned Numbers Authority (IANA) listed
unassigned ports.
- `free_port()` will not return any TCP port currently in use - so
`free_port()` can safely be used to allocate a ports programmatically without collisions - great for
automated testing or browser automation in general
