Instantly convert any domain name to its IP address with our free online Domain to IP lookup tool. Get both IPv4 (A record) and IPv6 (AAAA record) addresses in seconds using Google's reliable public DNS infrastructure. Supports single domain lookups and bulk domain resolution (up to 10 domains simultaneously). Perfect for network engineers, web developers, IT administrators, and anyone troubleshooting connectivity or hosting issues.
A Domain to IP converter (also called a domain to IP lookup tool, DNS resolver, or hostname to IP lookup) is an online utility that performs DNS resolution - the process of translating a human-readable domain name into the machine-readable IP address where the website or service is hosted.
The internet's addressing system uses numerical IP addresses to route traffic between computers. Every website, API, mail server, and internet-connected service has an IP address. Domain names like "example.com" are simply user-friendly aliases that map to these IP addresses through the Domain Name System (DNS). When you type a domain into your browser, your computer secretly performs this conversion dozens of times per second - for the main domain, subdomains, CDN assets, APIs, and more.
Our tool makes this process explicit and controllable, letting you see exactly which IP addresses a domain resolves to, query both IPv4 and IPv6 addresses simultaneously, and check up to 10 domains in a single bulk lookup operation - all powered by Google's public DNS API for maximum accuracy.
IPv4 (Internet Protocol version 4) is the original IP addressing system, using 32-bit addresses written in four groups of numbers separated by dots, like 142.250.80.46. The IPv4 address space has approximately 4.3 billion unique addresses.
With the explosive growth of the internet and IoT devices, IPv4 addresses are now nearly exhausted. Most websites today have at least one IPv4 address for backwards compatibility with older systems and ISPs that don't yet support IPv6.
A domain can have multiple IPv4 addresses configured (round-robin DNS for load balancing), which is why our tool shows all IP addresses, not just one.
IPv6 (Internet Protocol version 6) is the next-generation addressing system using 128-bit addresses written as eight groups of hexadecimal numbers, like 2607:f8b0:4004:c08::65. The IPv6 address space has 340 undecillion unique addresses - effectively unlimited.
Major internet providers, mobile networks, and cloud platforms have rapidly adopted IPv6. Google reports that over 45% of its traffic globally is now served over IPv6. If your server has an IPv6 address (AAAA record), IPv6-capable users may preferentially connect via IPv6.
Not all domains have IPv6 addresses yet. When our tool returns no IPv6 address, it means the domain hasn't configured an AAAA record - not that the site is unreachable.
When you enter a domain into your browser or our tool, here's the DNS resolution process that happens behind the scenes:
Quickly look up IP addresses to configure firewall rules, whitelist specific IPs, set up VPN exceptions, troubleshoot routing issues, and verify that hosting changes have propagated correctly. Bulk lookup is especially useful for whitelisting multiple domains at once.
Check which IP addresses a domain resolves to during hosting migrations, CDN configurations, and Kubernetes ingress setup. Verify that load balancers are distributing traffic correctly by checking multiple IP addresses returned for a single domain.
Identify the hosting infrastructure behind suspicious domains, map attack surfaces, correlate domains using the same IP infrastructure, and investigate phishing campaigns. Domain-to-IP lookup is a fundamental OSINT (Open Source Intelligence) technique.
Verify website hosting during site migrations, check if multiple domains owned by a client are on the same server IP (which could affect link equity in some scenarios), and troubleshoot indexing issues caused by server IP changes.
Look up the IP address of a mail server to cross-reference with blacklists, verify that MX record IPs have PTR records configured, and confirm that email is routing through the expected server infrastructure.
Satisfy curiosity about where a website is hosted, check if two websites are on the same server, or troubleshoot connectivity issues by confirming that a domain resolves to the expected IP address.
It's common for our tool to return multiple IP addresses for a single domain. This happens for several reasons:
If a domain uses round-robin DNS or GeoDNS, different IP addresses may be returned on successive queries to distribute traffic. CDNs like Cloudflare use anycast routing, meaning the "same" IP address routes to different physical servers based on your network location. This is by design and indicates a properly configured, scalable hosting setup.
After getting the IP address from our Domain to IP tool, you can use an IP geolocation or WHOIS lookup tool to find out which country, region, and ISP the IP belongs to, and which organization has been allocated that IP block. This is done through ARIN (Americas), RIPE (Europe), APNIC (Asia-Pacific), and other Regional Internet Registries.
This typically means the domain does not exist, is not configured with A or AAAA records, or the domain is expired and has been removed from the DNS system. It could also occur if you made a typo in the domain name. Double-check the spelling and try again.
Yes. DNS is a public system by design. Every internet-connected computer performs IP address lookups constantly just to function normally. Querying DNS records for any domain is entirely legal, publicly accessible, and is a standard practice for system administrators, security researchers, and developers.
IPv4 (A records) and IPv6 (AAAA records) are separate record types in the DNS system, and a server must be explicitly configured to support both. We show them separately so you can clearly see which protocols are supported and confirm both versions are configured correctly for dual-stack deployments.
