Resolve any domain or IP address to its server location, ASN, and hosting provider.
Try a sample:
Enter an IPv4 or IPv6 address directly, or paste any domain name, and we resolve it to its live server IP on the fly and pull the underlying server details.
Pinpoint country, region, city, local timezone, and approximate geographic coordinates mapped to the IP address.
Identify the Autonomous System Number (ASN), ISP, and network organization operating the IP block to see which network actually hosts the infrastructure.
Tracing the Infrastructure Behind a Domain
Every live website and mail server eventually points to a physical network. Mapping a domain to its IP address and Autonomous System (ASN) reveals whether a project sits behind an enterprise CDN, runs on a major cloud provider, or shares a budget hosting subnet with suspicious neighbors. DomainKits pairs live DNS resolution with IP geolocation and network data so you can inspect the network layer in one step.
Frequently Asked Questions
How do I find the IP address and hosting provider of a website?
Type either an IP address (IPv4 or IPv6) or a domain name into the search box above and click Lookup. If you enter a domain name, the tool queries its live DNS record to find the primary server IP, then returns the geographic location (country, region, city, coordinates, and timezone) alongside the network operator, ISP, and Autonomous System Number (ASN).
What is IP Lookup, and how do you read server and hosting signals accurately?
An IP lookup translates a numerical network address into physical location data and organizational ownership records.
Because modern web traffic often passes through proxies and cloud networks before reaching an origin server, we use four baseline heuristics when reading IP lookup results:
- CDN Edge vs. Origin Hosting: If a domain resolves to an ASN owned by Cloudflare, Fastly, Akamai, or CloudFront, the IP location reflects an anycast edge node, not necessarily where the backend origin server is physically hosted.
- Cloud vs. Bulletproof ASNs: Legitimate SaaS and commercial brands typically sit on major cloud networks (such as AWS, Google Cloud, Azure, or DigitalOcean). Phishing and malware campaigns frequently cluster on lesser-known offshore ASNs with lax abuse policies.
- Geographic & Timezone Alignment: Comparing a server's regional IP allocation and timezone against the language or target market of the website helps validate whether a regional business is hosted locally or routed elsewhere.
- Pivoting from IP to ASN & DNS: A single IP only tells part of the story. Checking the parent ASN via ASN Lookup shows the full scale of the hosting provider, while DNS Check reveals if mail servers (MX) expose the true origin IP behind a CDN.
How accurate is IP geolocation data, and where does it come from?
Our geolocation data is powered by the MaxMind GeoLite2 database. Country-level and ASN-level attribution is typically reliable, while city-level coordinates represent the registered hub of the ISP or data center rather than an exact street address.
How can I investigate a suspicious IP or domain further?
Use IP Lookup as the starting point of an infrastructure check, then pivot across our connected tools:
- Check the Network Owner: Take the ASN number from your IP result and run it through ASN Lookup to inspect all IPv4/IPv6 prefixes controlled by that organization.
- Uncover Unproxied Records: Run the domain through DNS Check and Subdomain Finder, since subdomains and MX mail records often point directly to the origin server IP even when the root domain sits behind a CDN.
- Verify Reputation: Check if the domain is flagged on security blocklists using Safety Check.
