Domain - IP Conversion
Convert a domain name to an IPv4 address
Features
Gets the IP via DNS name resolution
Looks up the actual server IP address from the domain name
Supports IPv4 and IPv6
Retrieves both A and AAAA records and lists them
Batch convert up to 100 entries
Convert multiple domains at once, separated by line breaks
Also supports pasting URLs
Automatically extracts the domain part from https or path-included URLs
How to use
Enter the domain name
Enter the domain name in the input field; for multiple, use line breaks, up to 100 entries
Run the convert button
Press the convert button to query DNS on the server side and retrieve the IP
Expand the results and copy
Open the results for each domain and copy the IP address with the copy button
Use cases
Confirming a server move
Confirm whether the domain's target IP has switched to the new server
Isolating connection problems
Determine DNS configuration issues from whether name resolution succeeds
Checking IPv6 support status
Grasp a site's IPv6 support from the presence of an AAAA record
Batch inspection of multiple domains
Check the IP assignments of many domains in operation all at once
Basic Knowledge
What is Name Resolution (DNS Lookup)?
Name resolution is the process of converting human-readable domain names into IP addresses that computers use for communication. This is done by querying DNS, a globally distributed database.
Difference Between IPv4 and IPv6
- IPv4：IPv4 is the traditional IP address format expressed as four numbers, such as 192.0.2.1. It has a limit of approximately 4.3 billion addresses and depletion is progressing.
- IPv6：IPv6 is a new IP address format expressed in hexadecimal notation, such as 2001:db8::. It allows for virtually unlimited address assignments.
Safety and privacy
Server-side processing
Input is processed on the server; only information necessary for the inquiry is sent.
Temporary processing only
For DNS name resolution, temporary processing occurs on the server, then data is discarded after results are returned.
Communications encrypted with HTTPS
All sent and received data is encrypted by TLS and cannot be read by third parties.
No transmission to third parties
Input content is not sent to external services such as ad networks or trackers.
Sent only to DNS servers
For name resolution, only the target domain name is sent to external DNS servers
