IP Information

Introduction

IP Information provides a comprehensive view of any IP address — including geolocation, ASN, ISP, hostname, and common reputation/blacklist hints. This tool helps site owners, security analysts, and support teams quickly understand who owns an IP, where it’s located, and whether it might be associated with abuse or a cloud provider. Use it to investigate suspicious traffic, verify server locations, or audit network connections.

What is this tool?

The tool queries public DNS, BGP/ASN records, and geolocation databases to collect details about an IP address. Typical outputs include the IP type (IPv4/IPv6), reverse DNS (PTR) name, Autonomous System Number (ASN) and organization, ISP name, country/region/city, approximate latitude/longitude, and any known abuse/blacklist flags. Results are based on public datasets and third-party providers, so accuracy can vary.

Why use this tool?

• Security investigations: Quickly identify if an IP belongs to a known cloud provider, VPN, or a suspicious ASN.
• Log analysis: Map IPs seen in logs to ISPs and regions for better triage and reporting.
• Deliverability & reputation: Spot IPs that might be on blocklists or have poor reputation impacting email or service access.
• Deployment validation: Verify that servers are in the expected region/ASN after provisioning or migration.
• Customer support: Provide context (ISP, region) when troubleshooting user connectivity issues.

How to use it

1. Enter an IP address (IPv4 or IPv6) or leave blank to check your public IP.
2. Click “Lookup” or “Get Info.”
3. Review returned fields: reverse DNS, ASN, ISP, country, city (if available), latitude/longitude, and any blacklist hints.
4. Use the ASN or ISP details to dig deeper (WHOIS, BGP tools) or to contact the provider if needed.
5. If geolocation seems wrong, try alternate lookups or cross-check with other databases — geolocation is approximate.

Example

Input: 203.0.113.10
Output (sample):

• Reverse DNS: host.example.net
• ASN: AS15169 (Google LLC)
• ISP: Google Cloud
• Location: Mountain View, CA, United States
• Coordinates: 37.4220, -122.0841
• Notes: IP belongs to a cloud provider; check for dynamic or ephemeral instances

FAQ

Do you store queried IPs?
No — lookups are performed live and are not retained. If your implementation logs queries for debugging, make sure this is documented in your Privacy Policy.

How accurate is geolocation?
Geolocation is approximate. Results depend on third-party databases and provider data; city-level accuracy can vary. Use ASN/ISP plus reverse DNS for stronger attribution.

Why does ASN/ISP differ from other tools?
Different services use different data sources and update schedules. ASN comes from BGP tables, while ISP names and geolocation are derived from provider datasets and can be updated at different times.

Can this reveal the origin server if a CDN is used?
Often CDNs and proxies hide the origin IP. This tool reports public-facing signals only; origin IPs may be obscured behind CDNs or WAFs.

How should I act on blacklist hints?
If an IP shows blacklist hits, confirm on the listed blacklist provider’s site and follow their delisting or remediation procedures. For shared/cloud IPs, consider contacting the provider or moving to a different IP range if necessary.
