How to Find the IP Address of a Website
Every website you visit has a numerical address behind it — an IP address that your browser uses to actually locate and connect to the server. The domain name (like example.com) is just a human-readable label. Under the hood, the Domain Name System (DNS) translates that label into an IP address every time you make a request.
Knowing how to look up that IP address is a practical skill for developers, sysadmins, and curious users alike — useful for troubleshooting connectivity issues, verifying DNS propagation, diagnosing server problems, or understanding hosting infrastructure.
Here are the most reliable methods, from the command line to browser-based tools.
Method 1: Use the ping Command 🖥️
The fastest method for most users is the ping command, available on Windows, macOS, and Linux without installing anything.
How to use it:
- Open your terminal or command prompt
- Type:
ping example.com - Press Enter
The output will show the IP address in brackets immediately — something like PING example.com (93.184.216.34). You don't even need the ping to succeed; the IP resolves in the first line.
What to keep in mind:ping returns one IP address. Sites using load balancing or CDN infrastructure (like Cloudflare or Akamai) may have dozens of IP addresses rotating across requests. What you see is the one your machine resolved at that moment.
Method 2: Use nslookup for DNS Detail
nslookup is a dedicated DNS query tool built into Windows, macOS, and Linux. It gives you more structured output than ping.
Usage:
nslookup example.com The result shows both the DNS server your machine used and the resolved IP address (or multiple addresses, if the domain has more than one A record). This is particularly useful when you're debugging DNS propagation after changing hosting providers or nameservers.
You can also query a specific DNS server directly:
nslookup example.com 8.8.8.8 This tells nslookup to use Google's public DNS (8.8.8.8) instead of your ISP's resolver — helpful for checking whether DNS changes have propagated globally yet.
Method 3: Use dig on Linux or macOS
dig (Domain Information Groper) is the preferred tool for developers and network engineers who want precise, unambiguous DNS output.
Usage:
dig example.com The ANSWER SECTION of the output shows the A record (IPv4) or AAAA record (IPv6) mapped to the domain. You can request specific record types explicitly:
dig example.com A dig example.com AAAA dig is not installed by default on Windows, but it's available through tools like BIND for Windows or the Windows Subsystem for Linux (WSL).
Method 4: Online DNS Lookup Tools 🌐
If you prefer not to use the command line, several web-based tools perform DNS lookups instantly:
| Tool | What It's Good For |
|---|---|
whatismyipaddress.com | Quick A record lookup |
dnschecker.org | Global DNS propagation across multiple servers |
mxtoolbox.com | Full DNS record inspection (A, MX, TXT, CNAME) |
nslookup.io | Clean interface, multiple record types |
ipinfo.io | IP lookup with geolocation and ASN data |
These tools are especially useful when you need to check how DNS has propagated across different regions — something local command-line tools can't easily show.
IPv4 vs. IPv6: Which One Are You Getting?
Most DNS lookups return an IPv4 address (four numbers separated by dots, like 93.184.216.34). But many servers now also support IPv6 (a longer hexadecimal format, like 2606:2800:220:1:248:1893:25c8:1946).
Whether your lookup returns IPv4, IPv6, or both depends on:
- Whether the domain has both A records (IPv4) and AAAA records (IPv6) configured
- Whether your network and OS prefer IPv6 when available
- Whether the hosting provider has enabled IPv6 on the server
Most modern operating systems default to IPv6 when available, so your browser may be connecting over IPv6 even if you've only ever seen the IPv4 address listed.
When the IP Address Isn't the Whole Picture
This is where things get more nuanced. Several factors affect what the IP address you find actually represents:
CDNs and reverse proxies — If a site uses Cloudflare, Fastly, or a similar CDN, the IP you resolve belongs to the CDN's edge server, not the origin server where the website files actually live. You're seeing the proxy, not the source.
Shared hosting — Many domains can share a single IP address. Finding the IP doesn't identify the specific site; other sites on that server share the same address.
Dynamic IPs — Some servers change their IP addresses over time, particularly in autoscaling cloud environments (AWS, Google Cloud, Azure). An IP that's valid today may route differently tomorrow.
Geolocation routing — Large services use anycast or GeoDNS to return different IPs to users in different regions. Running the same lookup from New York and Tokyo may return completely different addresses — both correct, for that region.
What the IP Tells You (and What It Doesn't)
Once you have the IP, tools like ipinfo.io or whois lookups can reveal the ASN (Autonomous System Number), the organization that owns the IP block, and rough geolocation data. This can confirm whether a site is hosted on AWS, Google Cloud, a particular data center, or a CDN.
What it won't tell you is the origin infrastructure behind a proxy, the specific server configuration, or anything about the site's software stack — that requires different tools entirely.
The right approach to finding and interpreting a website's IP depends heavily on why you need it — whether you're debugging DNS propagation, investigating hosting infrastructure, troubleshooting a connectivity issue, or just satisfying curiosity. Each of those use cases points toward different tools and a different level of detail worth pursuing.
