What is the Domain Name System?
The Domain Name System (DNS) is a critical part of the Internet infrastructure. It is responsible for translating human-readable domain names (such as www.example.com) into IP addresses that computers can understand.
Why is DNS Important for Auction Domaining?
If you’re involved in buying and selling domain names, you need to have a solid understanding of DNS. Here’s why:
- When buying expired domains, you need to make sure they still have good DNS records.
- When flipping domains, you’ll want to consider the SEO implications of changing DNS settings.
- When selling domains, you need to properly transfer the domain’s DNS to the new owner.
How Does DNS Work?
Here’s a quick overview of how DNS works:
- When you type a domain name into your web browser, your ISP’s DNS server looks up the IP address associated with that domain name.
- If your ISP’s DNS server doesn’t already have the answer cached, it will query other DNS servers until it finds the IP address.
- Once the IP address is found, your web browser uses it to connect to the appropriate server and retrieve the website content.
Common DNS Records You Should Know
Here are some common DNS records you’ll encounter when buying and selling domains:
| DNS Record | Explanation |
|---|---|
| A (Address) | Points a domain name to an IP address. |
| CNAME (Canonical Name) | Aliases one domain name to another (e.g., www.example.com to example.com). |
| MX (Mail Exchanger) | Specifies the mail server(s) for a domain. |
| TXT (Text) | Can contain arbitrary text data, often used for verification or authentication purposes. |
Conclusion
As you can see, DNS is critical for successful auction domaining. By understanding how it works and the different DNS records you may encounter, you can make more informed decisions when buying and selling domains.
