IP Geolocation Lookup
Look up any IPv4 or IPv6 address to find its country, region, city, ASN, ISP, organisation and privacy flags. Your own public IP is detected automatically on page load.
What is the IP Geolocation Lookup Tool?
The IP Geolocation Lookup tool resolves any IPv4 or IPv6 address to its associated geographic location, network ownership, and routing information. For each IP address, it returns the country, region, city, postal code, latitude and longitude, timezone, ASN (Autonomous System Number), ISP name, and organisation. Your own public IP address is auto-detected on page load, so you can immediately see how your connection appears to external services. Lookups are performed in real time via the ipapi.co API, which aggregates data from multiple regional Internet registries and geolocation databases.
IP geolocation is a foundational networking skill for DevOps and SRE engineers. Debugging a production incident often requires quickly identifying whether unexpected traffic is coming from a cloud provider's IP range, a CDN edge node, a corporate proxy, or a residential ISP. CDN debugging, geo-restriction testing, security investigation, and traffic analysis all rely on the ability to map IP addresses to meaningful location and network ownership information.
When to Use This Tool
- Debugging CDN edge behavior: Look up the IP address returned by a CDN to confirm it resolves to the expected edge PoP (Point of Presence) in the target region, verifying that geo-based routing is working correctly.
- Investigating suspicious production traffic: During a security incident or anomaly investigation, look up source IPs from access logs to identify whether traffic originates from a known cloud provider, a Tor exit node, or an unexpected country.
- Geo-restriction testing: Verify that your geo-blocking or geo-routing rules are effective by looking up IPs associated with the target countries or regions and comparing them against your firewall or CDN rules.
- Third-party API integration debugging: Confirm which public IP address your outbound traffic is using when connecting to third-party APIs that whitelist by IP address, especially from cloud environments where the egress IP may not be obvious.
How It Works
The tool makes a request to the ipapi.co REST API, which returns a JSON object containing all available geolocation and network attributes for the queried IP. For your own IP auto-detection, the API is called without a specific IP address, and the service identifies the requesting IP from the HTTP connection. For manual lookups, the IP address you enter is appended to the API endpoint URL. The response data is then rendered into the location cards and detail table in your browser. All previous lookups are stored in the browser's local storage so you can quickly revisit recent IP addresses without re-typing them.
Frequently Asked Questions
How accurate is IP geolocation?
IP geolocation accuracy varies significantly by IP type and region. For residential ISP addresses in North America and Western Europe, geolocation databases are typically accurate to the city level — often within 50 kilometres. For data center and cloud provider IPs, the location returned is usually the data center's physical location, which may differ from the actual user's location if they are connecting through a VPN or proxy. IPv6 addresses are generally less accurately geolocated than IPv4 addresses because the geolocation databases have had less time to build coverage. Corporate networks often geolocate to their headquarters address rather than the individual office connecting to the internet. For DevOps use cases like CDN PoP verification and cloud IP identification, accuracy is usually high because cloud providers maintain well-documented IP ranges.
Does this tool track my IP address?
Your public IP is detected by making a request directly from your browser to the ipapi.co API, which identifies the connecting IP from the HTTP request the same way any web server would. DevOpsArsenal itself does not intercept, log, or store your IP address — the request goes directly from your browser to ipapi.co without passing through any DevOpsArsenal server. The ipapi.co service has its own privacy policy governing how it handles API requests. Lookup history is stored locally in your browser's localStorage and is never transmitted anywhere. If you are concerned about exposing your actual IP address, you can manually enter any IP in the lookup field instead of using the auto-detect feature.
What is an ASN and why is it useful for DevOps engineers?
An ASN (Autonomous System Number) is a globally unique identifier assigned by regional Internet registries (ARIN, RIPE, APNIC, etc.) to a network operated by a single organisation under a unified routing policy. Every major ISP, cloud provider, CDN, and large enterprise has one or more ASNs. For DevOps engineers, ASN information is valuable in several scenarios: identifying whether an IP belongs to AWS (AS16509), Google Cloud (AS15169), Cloudflare (AS13335), or Azure (AS8075) helps determine whether traffic is from a cloud workload or a real user; ASN-based firewall rules can block or allow entire cloud providers rather than maintaining individual IP ranges; and during security incidents, ASN information immediately tells you whether a suspicious IP belongs to a hosting provider commonly used for botnets or to a legitimate CDN. The ASN is displayed alongside the organisation name in the lookup results.
