List floating IPs in the active scope

Returns the floating (public) IP addresses allocated in the active tenant/subscription/project scope, as rendered by the Floating IPs page on route load. This single endpoint also serves the search/filter/sort/paginate behavior (canonical action network.floating_ip.search_filter_sort): the free-text q parameter matches the address, pool, and associated instance/port names; the status filter maps to the UI chips All / Associated (ACTIVE) / Unassociated (DOWN); sort+order cover the sortable columns (ip, status, pool, instance, createdAt); page+pageSize paginate. Each row exposes the stable identifiers (id, ip, port, router) the view needs for follow-up actions. No resource state is mutated by this call. Validation: scopeId must reference a scope the caller can read, otherwise 403 FORBIDDEN; unknown scope → 404 NOT_FOUND; malformed pagination/sort/filter values (negative page, unknown sort key, status outside ACTIVE|DOWN) → 422 VALIDATION_FAILED. Async & state: Synchronous read; no state change. Transitional allocation states created by network.floating_ip.create are visible here as soon as the allocation is accepted. Errors: 401 when unauthenticated; 403 when the caller lacks reader access to the scope; 404 when the scope does not exist or is soft-deleted; 422 on invalid query parameters; 429 on rate limit; 500 on backend failure. Idempotency/Concurrency: Safe, cacheable; no idempotency key required. Responses may carry an ETag for conditional GET but no If-Match handling applies.
