How to use Domain to IP Lookup
The Domain to IP tool resolves a hostname to the IP addresses behind it, performing the everyday forward DNS lookup that turns a name like example.com into the IPv4 and IPv6 addresses servers actually connect to. It is the most direct way to find where a domain is hosted, to confirm a DNS change has taken effect, or to gather the address you need for a firewall rule, an SSH session or a traceroute. Because a single name often resolves to several addresses for load balancing, the tool lists every address returned.
- Enter the domain or hostname you want to resolve.
- Click Resolve to perform a live forward DNS lookup.
- Read the IPv4 (A) and IPv6 (AAAA) addresses returned.
- Note multiple addresses, which indicate load balancing or a CDN.
- Copy an address for use in a firewall, SSH or diagnostic tool.
One name, many addresses
Large sites rarely sit on a single server. A hostname often resolves to several IP addresses so traffic can be spread across machines, and content delivery networks return whichever address is nearest to the person asking. This means the IP you see may differ from what someone in another country sees, and may change over time, which is entirely normal. When a name resolves to a CDN address you are seeing the edge node rather than the origin server, which is exactly how the system is meant to work.
Forward versus reverse resolution
Resolving a name to an address is forward DNS and is what this tool does. The opposite direction, turning an address back into a name, is reverse DNS and uses PTR records that the IP block’s owner controls. The two do not always agree, because forward records are set by the domain owner while reverse records are set by the network operator. When you need to confirm what a given IP claims to be — for instance when checking a mail sender — pair this lookup with a reverse-DNS check.
| Record | Returns |
|---|---|
| A | IPv4 address(es) |
| AAAA | IPv6 address(es) |
