DNS TOOLS
DNS Checker
Check DNS records for any domain name and
understand how your domain is resolving across the internet.
What is DNS?
The Domain Name System (DNS) is the system that
translates human-readable domain names into information
that computers use to locate services on the internet.
What is a DNS Checker?
A DNS checker helps you view and understand the DNS
records associated with a domain. It can be useful when
troubleshooting websites, email delivery and DNS changes.
DNS Record Types
A Record
Maps a domain name to an IPv4 address.
AAAA Record
Maps a domain name to an IPv6 address.
CNAME Record
Points one hostname to another hostname.
MX Record
Specifies the mail servers responsible for email delivery.
NS Record
Identifies the authoritative name servers for a domain.
TXT Record
Stores text information associated with a domain.
DNS Propagation
When you change a DNS record, the updated information
may not appear everywhere immediately. DNS resolvers
can cache records based on their configured TTL.
💡 Tip
DNS changes can take time to become visible because
different DNS resolvers may have cached earlier values.
What is TTL?
TTL, or Time To Live, determines how long DNS information
can be cached before a resolver checks for an updated record.
TTL
300 seconds
Frequently Asked Questions
1. What is DNS?
DNS (Domain Name System) is a system that translates domain names, such as example.com, into IP addresses that computers use to find websites and online services.
2. What is a DNS record?
A DNS record contains information that tells DNS servers how a domain should work. Different record types are used for websites, email, verification, and other services.
3. What is an A record?
An A record connects a domain or subdomain to an IPv4 address. It is commonly used to point a domain name to a web server.
4. What is an AAAA record?
An AAAA record connects a domain or subdomain to an IPv6 address. It serves a similar purpose to an A record but uses IPv6.
5. What is a CNAME record?
A CNAME record points one domain or subdomain to another hostname. It is commonly used when a service is hosted under another domain name.
6. What is an MX record?
An MX (Mail Exchange) record specifies which mail servers should receive email for a domain. MX records can also have a priority value to determine which server should be preferred.
7. What is DNS propagation?
DNS propagation is the process by which DNS changes become available across different DNS servers and resolvers around the internet. The time can vary depending on caching and TTL settings.
8. How long does DNS propagation take?
DNS changes can sometimes appear within minutes, but they may take longer depending on DNS caching and the record's TTL. Different users or locations may see the updated information at different times.
9. What is TTL?
TTL (Time To Live) specifies how long a DNS record can be cached by DNS resolvers before they request updated information. A lower TTL can allow changes to be detected sooner, while a higher TTL can reduce repeated DNS lookups.
