Hostname to IP: Online IPv4 and IPv6 DNS Record Lookup
Hostname to IP is a browser-based DNS lookup that resolves a hostname into its IPv4 A and IPv6 AAAA records. Queries use DNS-over-HTTPS through Cloudflare or Google, and results show each record's type and TTL alongside the DNSSEC AD flag. The lookup runs in your browser, but the hostname query is sent to the DNS provider; a network connection is required.
Hostname to IP is a browser-based DNS lookup for developers and anyone who needs to resolve a hostname to its IPv4 A and IPv6 AAAA records. Use it to check DNS results without installing a local command-line client. The tool displays the record type, TTL, and DNSSEC AD flag with the results.
To perform a lookup, enter a hostname and send a query over DNS-over-HTTPS through Cloudflare or Google. The response can include A records for IPv4 addresses and AAAA records for IPv6 addresses. Results include the TTL for each record and the DNSSEC AD flag; the tool does not describe additional conversion or parsing options.
A hostname is a readable name used to identify a host, while an IP address is the numeric address returned in DNS records. Looking up both A and AAAA records can help you see which address types are associated with a name. The displayed TTL and DNSSEC AD flag also provide useful context when reviewing a DNS response.
The lookup runs in your browser, and the tool itself does not send the query to its own server. However, this is not an offline lookup: the hostname or IP address you enter is sent to the public DNS-over-HTTPS resolver, so that provider sees the query. You need a network connection to get results.
This free tool is useful for developers and DevOps engineers who want to inspect DNS results from a browser, whether they are troubleshooting hostname resolution or checking record details. It offers a practical alternative when a local command-line DNS client is not available.
Step 1: Enter the hostname you want to look up. Check the spelling so the DNS query uses the name you intend to resolve.
Step 2: Adjust the available options before running the lookup. Queries are sent over DNS-over-HTTPS through Cloudflare or Google.
Step 3: Review the returned A and AAAA records. Each result includes its record type and TTL, as well as the DNSSEC AD flag.
Step 4: Copy the result for your notes or workflow. The lookup needs an active network connection to reach a DNS provider.
Use case: Handle a routine Hostname to IP lookup without installing a command-line tool or other software locally.
Use case: Run a DNS lookup in your browser from the machine you are currently using, rather than setting up a local DNS client.
Use case: Reach a DNS-over-HTTPS resolver from your browser when you do not have a command-line client available.
Use case: Check whether a hostname returns IPv4 A records, IPv6 AAAA records, or both before investigating a connection issue.
Use case: Inspect the TTL shown for a DNS record when checking how long that record is intended to be cached.
Use case: Review the DNSSEC AD flag alongside the returned records when you are checking DNS response details.
