Network
Expand many CIDR ranges from one file.
overview
When recon leaves a file of network blocks, decant-file is the managed Network node that reads cidr-addresses and writes one flat host list as FILE and FOLDER.
Cloud-range exports, ASN prefix dumps, or inventory CIDRs that must become concrete IPs before a scanner. No CLI flags; the file is the whole interface.
Use the single-address Decant variant for one range. For aggregation, slicing, or host counting instead of full expansion, mapcidr.

use cases
Read a file of CIDR blocks and emit every IP across all of them as one flat list, ready for a scanner or prober.
Convert provider CIDR exports or ASN-derived prefixes into concrete addresses so downstream nodes enumerate the hosts inside them.
Hand the expanded addresses to naabu, rustscan, or masscan, which want a flat host list rather than network notation.
Turn a mixed set of network blocks into a uniform IP list early so every later stage reads the same format.

Use decant-file when a file of CIDR ranges must become a flat IP list. For a single range, Decant is simpler. For CIDR aggregation and slicing rather than full expansion, mapcidr.
Same expansion for one CIDR address instead of a file.
Aggregation, slicing, and expansion when a flat list is not enough.
Prints each IP in a range. Comparable range-to-host primitive.
