**Common DNS Records**

**1. A Record**\
Maps your domain to an IPv4 address. Use this record to point your domain or subdomain to a web server.

**Example:**

| Host     | Type | Value     | TTL  |
| -------- | ---- | --------- | ---- |
| @ (root) | A    | 192.0.2.1 | 3600 |
| www      | A    | 192.0.2.1 | 3600 |

***

**2. AAAA Record**\
Similar to an A record but maps your domain to an IPv6 address.

**Example:**

| Host     | Type | Value                         | TTL  |
| -------- | ---- | ----------------------------- | ---- |
| @ (root) | AAAA | 2001:0db8:85a3::8a2e:370:7334 | 3600 |

***

**3. CNAME Record**\
Maps a subdomain to another domain name (e.g., for CDN or external hosting services).

**Example:**

| Host | Type  | Value            | TTL  |
| ---- | ----- | ---------------- | ---- |
| www  | CNAME | example.com      | 3600 |
| blog | CNAME | blog.example.box | 3600 |

***

**4. MX Record**\
Used to direct email to your email provider’s server.

**Example:**

| Host     | Type | Value              | Priority | TTL  |
| -------- | ---- | ------------------ | -------- | ---- |
| @ (root) | MX   | mail.example.box   | 10       | 3600 |
| @ (root) | MX   | backup.example.box | 20       | 3600 |

***

**5. TXT Record**\
Used for various purposes like domain verification and email authentication (SPF, DKIM, DMARC).

**Example for SPF:**

| Host     | Type | Value                              | TTL  |
| -------- | ---- | ---------------------------------- | ---- |
| @ (root) | TXT  | "v=spf1 include:example.com \~all" | 3600 |

**Example for Domain Verification:**

| Host     | Type | Value                                   | TTL  |
| -------- | ---- | --------------------------------------- | ---- |
| @ (root) | TXT  | "google-site-verification=example12345" | 3600 |

***

**6. SRV Record**\
Defines services for specific protocols, often used for SIP or other specialized applications.

**Example:**

| Service | Protocol | Priority | Weight | Port | Target          | TTL  |
| ------- | -------- | -------- | ------ | ---- | --------------- | ---- |
| \_sip   | \_tcp    | 10       | 60     | 5060 | sip.example.box | 3600 |

***

**7. NS Record**\
Delegates a subdomain to different nameservers. Note: Modifying NS records for the root domain changes the domain's nameservers.

* **Example for Subdomain Delegation:**

  | Host      | Type | Value           | TTL  |
  | --------- | ---- | --------------- | ---- |
  | subdomain | NS   | ns1.example.box | 3600 |
  | subdomain | NS   | ns2.example.box | 3600 |

***

#### **Notes**

* **TTL (Time to Live):** Defines how long the DNS record is cached. The default is typically 3600 seconds (1 hour).
* **Propagation Time:** DNS changes can take up to 24 hours to propagate globally, but most updates occur within minutes.
