How to find a website’s IP address
Find the IP address behind any domain with a DNS lookup of its A/AAAA records. Step-by-step, plus what a CDN or proxy changes.
A website’s IP address is stored in its DNS A (IPv4) and AAAA (IPv6) records. Looking them up tells you where the site is hosted — with one caveat when a CDN or proxy sits in front.
Look up the A record
Run a DNS lookup for the domain and read its A/AAAA records — those are the IPs browsers connect to. A domain may return several for load balancing. This is the direct answer to "what IP is this site on?"
CDNs and proxies hide the origin
If a site uses a CDN like Cloudflare, the A record points at the CDN’s IP, not the real origin server — that is by design, to shield and accelerate the origin. So the IP you find may be the CDN edge, which is still useful for connectivity checks.
Step by step
Enter the domain in the DNS lookup tool.
Read the A record for the IPv4 address (and AAAA for IPv6).
If several are returned, the site is load-balanced across them.
If it uses a CDN, the IP is the CDN edge, not the hidden origin server.
