There are 2 possible places you can find this information in RTEMS
depending on how you use the networking stack.
The hosts are listed in /etc/hosts so a cat of that file will list them.
For DNS you can cat /etc/resolv.conf and NTP would be its configuration
file in /etc. There is code such as mkrootfs or something like that
which sets the file system up.
RTEMS also has a "feature" in the stack where some entries can be added
to internal tables in the stack. I am not sure there is a command to
dump these. It would not be difficult to add.

Not that I know of. I worked on a project many years ago where it was
added. The ping command from FreeBSD was used as the base.

I suspect the assumption is to use FreeBSD's documentation.
