The XiaTools IP Lookup tool allows you to instantly retrieve detailed geolocation, Autonomous System Number (ASN), and network ownership data for any IP address or domain name. Whether you are investigating network traffic anomalies, verifying server locations, or troubleshooting routing issues, this utility delivers the essential network intelligence you need right in your browser.
What is it
An IP lookup is a diagnostic process that queries regional internet registries (RIRs) and routing databases to uncover the administrative and geographical details tied to a specific internet protocol address. Every device connected to the internet relies on an IP address to communicate, and these addresses are systematically allocated to Internet Service Providers (ISPs), hosting companies, and enterprise organizations.
When you run a lookup, the tool aggregates data from sources like ARIN, RIPE, APNIC, LACNIC, and AFRINIC. It translates a raw numerical string—or a domain name—into human-readable context. This includes the physical country and city where the IP is registered, the organization that owns the block, the specific subnet range, and the Autonomous System Number (ASN) used for BGP routing across the global internet.
Why it matters
Understanding the background of an IP address is critical for network administration, cybersecurity, and website management. If you notice unusual login attempts or high volumes of traffic hitting your web server, an IP lookup helps you identify the origin of the traffic and the organization responsible for the network.
For IT professionals, tracking ASN and BGP routing details assists in diagnosing latency issues, packet loss, or peering bottlenecks between networks. Website administrators also use IP geolocation data to ensure compliance with regional data regulations, verify Content Delivery Network (CDN) edge routing, or implement geographic access controls to protect critical infrastructure against brute-force attacks.
How to use this tool
- Navigate to the XiaTools IP Lookup page.
- Enter a valid IPv4 address, IPv6 address, or domain name (such as example.com) into the input box.
- Press the Check button to query the network databases.
- Review the generated breakdown of network ownership, geolocation, and routing data displayed on your screen.
How to read the results
When you query an address, the tool displays several specific data points. Here is how to interpret a typical response for example.com:
- IP Address: The resolved numerical identifier, such as
93.184.216.34. This confirms the exact destination endpoint you are querying. - Hostname: The reverse DNS (PTR) record associated with the IP, such as
93.184.216.34.bc.googleusercontent.comor a dedicated server hostname. It indicates how the IP identifies itself on the reverse lookup tree. - ASN (Autonomous System Number): A unique number assigned to a network connected to the global routing table, such as
AS15133(Edgecast/Edgio) orAS15169(Google). This tells you which major network operator handles the routing for that IP. - CIDR Range / IP Block: The allocated subnet size, such as
93.184.216.0/24. This shows the boundary of the IP space owned or managed by the organization. - Organization / Owner: The administrative entity that holds the IP block registration, such as Edgecast Inc. or Cloudflare, Inc.
- Country and Region: The physical or registered location of the network or registrant, such as
United StatesorCalifornia, which helps determine the general geographic jurisdiction of the host.
Common problems and how to fix them
Incorrect Geolocation Data
Geolocation databases rely on router traceroutes and registry data updates, which can sometimes be outdated or inaccurate for mobile networks and newly allocated subnets.
To fix incorrect location reporting for your own infrastructure, submit a correction request directly to major geolocation database providers like MaxMind, IPinfo, or DB-IP. Ensure your reverse DNS (PTR) records and WHOIS organization data are up to date with your regional internet registry.
Domain Name Fails to Resolve
If you enter a domain name instead of an IP address and the tool returns an error, the domain may lack proper DNS configuration.
Verify your domain's DNS settings by checking that your A records (for IPv4) or AAAA records (for IPv6) point to an active, reachable IP address:
example.com. 300 IN A 93.184.216.34
example.com. 300 IN A 2606:2800:220:1:248:1893:25c8:1946
Private IP Range Not Found
If you attempt to look up a private IPv4 address—such as 192.168.1.1, 10.0.0.5, or 172.16.0.1—the tool will not return any global network or geolocation data.
Private IP addresses are non-routable on the public internet and are reserved for local area networks (LANs). Use local administrative tools like ipconfig on Windows or ifconfig/ip a on Linux to inspect private network configurations.
Best practices
- Combine with Traceroute: Use an IP lookup alongside traceroute utilities to map out the physical and logical path packets take across different ASNs.
- Verify Reverse DNS: Maintain accurate PTR records with your ISP or hosting provider to ensure your servers are easily identifiable during security audits.
- Monitor IP Reputation: Regularly check your public IP blocks against abuse databases to ensure your network hasn't been compromised or listed on spam blacklists.
