Every address Rollcall hands out is registered in the configured authority first; addresses others hold there are skipped. Rollcall's records carry the tag `rollcall` and the machine ID in the `rollcall_machine` custom field; only those are changed or deleted. Releases trigger a reconcile that also runs periodically. dns_name per address feeds the site's DNS sync. Delegated prefixes can be listed and imported as subnets. `rollcall ipam`.
