How this service works
Bulk is port 464 open: up to 20 hosts in one call, processed concurrently, results in input order with a per-item error field and a failure count. Same answer per item as the single endpoint. Batch enrichment for agents that hold a list. $0.10 per batch.
Output
An ordered array of per-host results (matching input order), each containing whether port 464 is open (boolean or status), a per-item error field indicating any per-host failure, and an aggregate failure count for the batch.
Example use cases
Kerberos exposure audit across fleet
“I have a list of 18 IP addresses in our corporate network — can you check all of them at once to see which ones have port 464 open? I want to know if any servers are unexpectedly exposing the Kerberos password-change port.”
Security scan before firewall rule change
“Before we push this new firewall policy, check these 12 hosts to confirm port 464 is properly blocked on all of them — tell me which ones still have it open and flag any errors.”
Cloud migration port validation
“We just migrated 20 servers to the new data center — can you run a batch check on all of them to verify port 464 is open and reachable, so we know Kerberos authentication will work after the cutover?”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/464?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you have a list of 2–20 hosts and need to check port 464 status for all of them efficiently in one API call rather than making separate single-host requests. It is ideal for fleet audits, batch security scans, or post-migration validation where concurrent execution and ordered results matter. Prefer the single-host endpoint when checking only one host to minimize cost.
Side effects
- Host unreachable or DNS resolution failure — reflected in per-item error field
- Timeout on individual hosts — counted in failure count, rest of batch still returned
- Input list exceeds 20 hosts — request rejected or truncated
- Network-level firewall blocking the probe — may report port as closed when actually filtered
- Invalid hostname or IP format — per-item error returned
