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.
