Added the following mode.

-e CUSTOM_SCRIPT="echo '1.1.1.1'" - Set to any shell command to run them and have the IP pulled from the standard output. This is sometimes useful in some specific usage.

I'm happy to merge this PR, but maybe the env var CUSTOM is a bit generic?

purerosefallen commented 4 years ago

If you think so, you may change it to something else. Perhaps CUSTOM_SCRIPT.

Changed.

oznu commented 4 years ago

Thanks for this.

I changed it to CUSTOM_LOOKUP_CMD for the final release.
