> FAQ
Q: What is a DNS record?
A: A DNS record is a database entry in the Domain Name System that maps a domain name to specific information, such as IP addresses or other data related to the domain.
Q: Why is it important to check DNS records?
A: Checking DNS records is crucial for several reasons:
- Troubleshooting: Helps identify and resolve website accessibility issues
- Security: Verifies proper configuration to prevent DNS-based attacks
- Email delivery: Ensures correct MX records for smooth email flow
- Performance: Confirms optimal DNS settings for fast website loading
- Migrations: Validates DNS changes during website or server migrations
- Compliance: Assists in maintaining required security standards
Regular DNS record checks help maintain a healthy, secure, and efficient online presence.
Q: What are the most common types of DNS records?
A: The most common types of DNS records include:
- A (Address) record: Maps a domain to an IPv4 address
- AAAA record: Maps a domain to an IPv6 address
- CNAME (Canonical Name) record: Aliases one domain to another
- MX (Mail Exchanger) record: Specifies mail servers for the domain
- TXT (Text) record: Stores text-based information, often used for SPF, DKIM, etc.
- NS (Name Server) record: Specifies authoritative name servers for the domain
Q: What is the difference between A and AAAA records?
A: A records map a domain to an IPv4 address (e.g., 192.0.2.1), while AAAA records map a domain to an IPv6 address (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334).
Q: What is a CNAME record used for?
A: A CNAME record is used to create an alias for a domain. It points one domain name to another, allowing multiple domains to resolve to the same IP address without duplicate A or AAAA records.
Q: How do MX records work?
A: MX records specify the mail servers responsible for handling email for a domain. They include a priority value to determine the order in which mail servers should be tried.
Q: What is a TTL in DNS records?
A: TTL stands for Time To Live. It specifies how long (in seconds) a DNS record should be cached by resolving name servers before requesting a fresh copy from the authoritative name server.
