ROASORT(8) - System Manager's Manual

roasort - order and deduplicate ROA ip address information

The roasort utility reads a list of newline separated ROA IP address information elements from stdin. Information elements are in the form: <address/prefixlength>[-maxlength].

The utility can be used in two ways: the error exit code indicates whether the input was in canonical form or not, and the canonical form is written to the standard output.

The utility sorts and deduplicates the elements according to the canonicalization process described in draft-ietf-sidrops-rfc6482bis.

The roasort utility exits 0 on success, and >0 if an error occurs, such as the input containing duplicates or being unsorted.
