Find the IP Addresses Behind a Website
Domain IP Lookup shows the address records a domain publishes in DNS. An A record supplies an IPv4 address, while an AAAA record supplies an IPv6 address. A website can have either type, both types, or several addresses within each type. The results keep the two families separate so you can see which addresses are available without treating one family as a replacement for the other.
The lookup is useful when checking a hosting change, comparing a subdomain with its expected server address, or identifying the public endpoints of a website. It reports DNS answers, not a scan of the web server. A listed address does not establish that the website is reachable, that its certificate is valid, or that a particular page will load.
Enter a Domain, Subdomain, or URL
Enter the exact hostname you want to check, such as example.com or shop.example.com. You can also paste a website URL. The lookup extracts its hostname and leaves out the scheme, port, path, query string, and fragment when requesting DNS records. For example, https://shop.example.com/catalog?item=42 checks shop.example.com, not a separate address for the catalog page.
- Enter one domain, subdomain, or website URL in the search field.
- Run the lookup and review the IPv4 and IPv6 results separately.
- Compare every returned address with the configuration you are investigating.
- Use the copy control to retain the result, or follow an address action for more information about a public IP.
An IP address by itself is not a website name for this lookup. Check the spelling of the hostname if the input is rejected. When you paste a URL, confirm that the displayed hostname is the one you intended to investigate before interpreting the addresses.
Read Multiple Addresses Correctly
Several addresses can be a normal part of a website's configuration. They may support traffic distribution, separate network paths, or a content delivery network. The lookup lists distinct addresses instead of selecting one as the website's only IP. An IPv4 result and an IPv6 result also do not necessarily identify the same physical server.
DNS answers can depend on the resolver, its location, and the website's routing policy. Your browser may therefore use a different address from one shown here. If a website uses a proxy or content delivery network, the published address may belong to that service rather than the server that stores the original website. These published addresses do not reliably identify a server hidden behind a proxy.
Understand TTL and Missing Results
TTL is the time to live supplied with a DNS answer, expressed in seconds. It indicates how long a resolver may cache that record. A cached answer can show a remaining lifetime rather than the original value configured by the domain owner. When a family has several addresses, the displayed TTL is the lowest value among those address records. For reference, 300 seconds is five minutes; it is not a measure of server speed.
A website with A records but no AAAA records can still work over IPv4. Likewise, an empty result for one family does not cancel a successful result for the other. The results distinguish a completed lookup with no matching records from a lookup failure. A technical failure means the answer could not be obtained, not that the address record definitely does not exist.
Follow Up on an Address
Public addresses have actions for viewing their approximate map location and opening IP details. These are separate checks on the selected address. A map describes the network address's estimated location, not necessarily the business's location or the physical server. Copy the result when comparing it with hosting settings or sharing the observed addresses with a network administrator.
