I would adjust the screen configuration or export the relevant environment
variable before starting screen.

There are other ways of obtaining a list of IPs on the command line (e.g.
via ip addr sh, or ifdata).

Ah, indeed.

Hm, so you actually invoke ip-screen on the command line, or would
you adjust the GNU screen configuration as needed then? FTR,
ip-screen was mainly written for usage inside GNU screen and for
performance reasons written in C:

  http://git.grml.org/?p=grml-scripts-core.git;a=blob;f=compile/ip-screen.c;hb=HEAD

If the same IP is present on more than one interface, ip-screen will list it
several times, e.g.

# ip-screen 
169.254.255.254 | 169.254.0.1 | 169.254.255.254 | 169.254.0.1 | 169.254.0.1 |
169.254.15.254

This takes up precious space in the status line.

It would also be nice to be able to exclude IPs from being printed at all
(individually or by subnet), for example by way of an environment variable or
command line option.
