Using the commandline network utilities from Emacs
Unbeknownst to many, Emacs comes with a full suite of wrappers around the common GNU network utilities.
Most of the utilities are just simple wrappers around their command-line equivalents, but in full technicolor; but some – like the
nslookup support – also adds full Emacs
Another useful feature is the built-in
ffap support (it means find file at point) and it will try to determine if the point is – if used interactively with the net utils below – on a hostname or IP and default to that.
The net utils library were written with the GNU libraries in mind, so Windows users may find the support a bit lacking. But you can always download the Win32 ports.
Here’s a list of utilities Emacs supports; invoke with
M-x. You may have to configure them to your liking, and you can do that by invoking
M-x customize-group RET net-utils RET.
ping, but on most systems it may run indefinitely; adjust
nslookupin non-interactive mode.

Very simple wrapper around the commandline tool
ftp. You are probably better off with TRAMP for all but low-level system administration.
