When you register a domain name, the Internet Corporation for Assigned Names and Numbers (ICANN) requires your domain name registrar to submit your personal contact information to the WHOIS database. Once your listing appears in this online domain WHOIS directory, it is publicly available to anyone who chooses to check domain names using the WHOIS search tool. There are a variety of third parties who may check domain names in the WHOIS check database, including:
- Individuals check domain names for expiration dates
- Registrars check domain names when transferring ownership
- Authorities check domain names when investigating criminal activity
An IP address (short for Internet Protocol address) is used to identify computers on the Internet. It works like a return address would on a piece of mail. When your computer or device sends a request, like a search on Google, it tags the request with your IP address. That way Google knows where to send the response.
DNS Propagation Checker lets you instantly perform a DNS lookup to check a domain names current IP address and DNS record information against multiple name servers located in different parts of the world.
This allows you to check the current state of DNS propagation after having made changes to your domains records.
