## Developed By: SplitIce <https://www.x4b.net>
## Free for commercial & Non-commercial use or whatever, just dot sue me.
##
## Usage:
## ./rbl.sh listcheck - Verify that all DNSBLS in the list are responding within a reasonable time (online)
## ./rbl.sh details [ip1] [...] - Fetch details for all RBL entries for one or many IP addresses
## ./rbl.sh count [ip1] [...] - Fetch a total count of RBL entries for many IP addresses
