How this service works
Bulk is port 88 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 results corresponding to each input host, where each item indicates whether port 88 is open or closed, a per-item error field describing any connectivity failure, and an overall failure count summarizing how many hosts could not be checked.
Example use cases
Kerberos availability audit across data centers
“I need to verify which of these 15 domain controllers have port 88 open — here's the list: dc1.east.corp, dc2.east.corp, dc1.west.corp, dc2.west.corp, dc3.west.corp, dc1.eu.corp, dc2.eu.corp, dc1.asia.corp, dc2.asia.corp, dc3.asia.corp, dc1.us.corp, dc2.us.corp, dc3.us.corp, dc4.us.corp, dc5.us.corp. Tell me which ones are reachable and which failed.”
Security scan for unexpected Kerberos exposure
“Scan these 20 public-facing IPs and tell me which ones have port 88 open — I want to know if any are unexpectedly exposing Kerberos: 203.0.113.1, 203.0.113.2, 203.0.113.3, 203.0.113.4, 203.0.113.5, 203.0.113.6, 203.0.113.7, 203.0.113.8, 203.0.113.9, 203.0.113.10, 198.51.100.1, 198.51.100.2, 198.51.100.3, 198.51.100.4, 198.51.100.5, 198.51.100.6, 198.51.100.7, 198.51.100.8, 198.51.100.9, 198.51.100.10.”
Pre-deployment Kerberos readiness check
“Before we roll out the new authentication service, check if port 88 is open and reachable on all 8 candidate KDC hosts: kdc-a.staging.internal, kdc-b.staging.internal, kdc-c.staging.internal, kdc-d.staging.internal, kdc-a.prod.internal, kdc-b.prod.internal, kdc-c.prod.internal, kdc-d.prod.internal.”
Technical details
Endpoint
GEThttps://ip.intel.rallylive.ca/bulk/ip/port/88?utm_source=zero.xyzWhen to prefer
Use this endpoint when you have a list of 2–20 hosts and need to check port 88 (Kerberos) status on all of them efficiently. It is preferred over calling the single-host endpoint repeatedly because it processes hosts concurrently and returns results in input order with structured per-item errors, making it ideal for bulk enrichment pipelines, infrastructure audits, or security scans where batching reduces latency and cost.
Side effects
- Host unreachable or invalid hostname returns a per-item error with failure incremented in the count
- Exceeding 20 hosts per batch may result in rejection or truncation
- Network timeouts on individual hosts return per-item errors without failing the whole batch
- Malformed input list returns a top-level error
- x402 payment failure prevents the call from being processed
