Hostname To IP
Look up the A (IPv4) and AAAA (IPv6) address records for a hostname in a clean, readable layout instead of raw command-line output.
🔒 This tool runs entirely in your browser. Your files are never uploaded to a server.
Example shown - live lookups for other hostnames need a server-side DNS resolver, which this preview doesn't connect to.
A records (IPv4)
AAAA records (IPv6)
How hostname resolution works
- Enter a hostname, such as example.com, without "http://" or a trailing path.
- A DNS resolver queries the domain's authoritative name servers for its A (IPv4) and AAAA (IPv6) records.
- The returned IP addresses are the ones your computer would actually connect to when visiting that hostname.
Why this needs a server component
DNS resolution is a low-level network protocol that browsers deliberately don't expose to JavaScript. A production version of this tool would query a DNS resolver from a small backend endpoint and return the result to the page - that backend piece isn't included in this frontend preview.
FAQ
What is an A record vs an AAAA record?
An A record maps a hostname to an IPv4 address. An AAAA record maps the same hostname to an IPv6 address. A domain can have one, both, or several of each.
Why does this only show a live result for the example hostname?
Web browsers cannot perform raw DNS lookups directly - that requires a server-side resolver. This page demonstrates the interface with a real example; wiring it to a live resolver is a backend integration outside the scope of this preview.
Can a hostname resolve to more than one IP address?
Yes. Many sites use multiple A or AAAA records for load balancing or redundancy, and DNS can return them in a rotating order.
Is this the same as a "traceroute" or "ping"?
No. This only resolves a hostname to its IP address records - it does not test connectivity, latency, or the network path to that address.
How we compare
| Feature | Online Tool Store | nslookup (CLI) | MXToolbox |

For a clean, distraction-free view of a domain's IP records without a terminal, Hostname To IP is a friendlier starting point.
