About this tool
What is the DNS Checker tool? DNS Checker A tool for verifying the propagation of DNS records across multiple DNS servers around the world. After changing your website’s DNS records, it takes time for the changes to propagate to all DNS servers worldwide. This tool helps you verify that the changes have reached different servers. Key Features Check DNS propagation across multiple servers in different countries Display the IP address of each DNS server Detect inconsistencies in records across servers Check multiple DNS record types (A, AAAA, MX, CNAME, TXT) View the propagation status for each server How Does It Work? Enter the domain name and the record type you want to check, and the tool will send DNS requests to multiple servers around the world and display the results, showing whether all servers return the same IP address. Practical Example: You migrated your website from an old host to a new one and changed the domain’s A record to point to the new IP address 104.21.45.67. You use the DNS checker and find that Google’s server (8.8.8.8) returns the new address, while a server in Germany still returns the old one. This indicates that propagation is not yet complete in some regions. Common Use Cases Website Migrations: Verifying the propagation of new records after migrating a website from one host to another Email Setup: Ensuring that MX records reach servers around the wor
