How this service works
Look up one or up to 50 IPv4/IPv6 addresses: country (ISO2 and name), autonomous system number and organisation, the matching network range, plus private/reserved address detection. Served from a monthly local copy of the DB-IP Lite country and ASN databases, so lookups are fast and nothing is sent to third parties. Use when an agent needs the country and network operator (ASN/organisation) of an IPv4 or IPv6 address for fraud checks, geo-compliance or log enrichment.
Output
Returns a JSON object with a results array where each entry contains the queried IP, its ISO2 country code and full country name, ASN number, AS organization name, the matching CIDR/range, and a boolean reserved flag. Also includes legal/terms links and a status field.
Example use cases
Fraud check on suspicious login IPs
“I have three IPs from failed login attempts — 45.33.32.156, 198.51.100.42, and 203.0.113.7 — can you tell me what countries they're from and who operates those networks so I can decide whether to block them?”
Geo-compliance filter for EU traffic
“Can you check these five IP addresses and tell me which ones are coming from EU countries? I need to know their country codes and ASNs for a GDPR compliance report.”
Enrich server access logs with network info
“I'm analyzing my nginx access logs and I want to enrich this list of IP addresses with their country names, ASN numbers, and network ranges — here are 20 IPs, can you run them through the lookup?”
Technical details
Endpoint
GEThttps://ip-geo-production.up.railway.app/v1/ip/lookup?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need fast, privacy-preserving IP-to-country and ASN lookups without sending data to a third-party API, and when batch lookups of up to 50 IPs at a time are sufficient. Ideal for fraud checks, geo-compliance, and log enrichment workflows where ASN/organization data is as important as country. Prefer alternatives if you need city-level geolocation, lat/lon coordinates, or real-time threat intelligence beyond country and network operator.
Side effects
- Missing 'ip' query parameter returns a validation error
- Supplying more than 50 IPs in a single request may be rejected
- Malformed IP addresses (non-IPv4/IPv6 strings) may return no result or an error for that entry
- Reserved or private IPs (e.g. 192.168.x.x) return reserved:true with no ASN/country data
- Service unavailability on Railway.app infrastructure returns a 5xx error
- DB-IP Lite data may lag up to one month behind real-world network changes
