# Understanding DNS Record Types | ||
|
||
DNS (Domain Name System) is essential for translating domain names into IP addresses, enabling browsers to find websites. Here's a quick guide to different DNS record types you might encounter: | ||
|
||
## **A Record** | ||
|
||
- **Purpose**: Maps a domain name to an IPv4 address. | ||
- **Example**: `example.com` → `192.0.2.1` | ||
|
||
## **AAAA Record** | ||
|
||
- **Purpose**: Maps a domain name to an IPv6 address. | ||
- **Example**: `example.com` → `2001:db8::1` | ||
|
||
## **CNAME Record** | ||
|
||
- **Purpose**: Alias for another domain name. It points one domain name to another. | ||
- **Example**: `www.example.com` → `example.com` | ||
|
||
## **MX Record** | ||
|
||
- **Purpose**: Specifies the mail servers responsible for receiving emails for the domain. | ||
- **Example**: `example.com` → `mail.example.com` | ||
|
||
## **TXT Record** | ||
|
||
- **Purpose**: Stores text-based information related to the domain, often used for verification and security purposes. | ||
- **Example**: `example.com` → `"v=spf1 include:_spf.example.com ~all"` | ||
|
||
## **SRV Record** | ||
|
||
- **Purpose**: Defines the location of servers for specific services, like VoIP or instant messaging. | ||
- **Example**: `_sip._tcp.example.com` → `sipserver.example.com` | ||
|
||
|
||
## **CAA Record** | ||
|
||
- **Purpose**: Specifies which certificate authorities (CAs) are allowed to issue certificates for the domain. | ||
- **Example**: `example.com` → `0 issue "letsencrypt.org"` | ||
