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

1

Enter the domain name

Enter the domain name in the input field; for multiple, use line breaks, up to 100 entries

2

Run the convert button

Press the convert button to query DNS on the server side and retrieve the IP

3

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
