Frequently Asked Questions

What is a DNS lookup?

A DNS lookup is the process of querying the Domain Name System to obtain information about a domain name, such as its IP address or mail server settings.

Why do I need to check DNS records?

DNS records need to be checked when setting up websites, email services, or troubleshooting domain-related issues. It helps verify proper configuration and diagnose problems.

How long do DNS changes take to propagate?

DNS changes can take anywhere from a few minutes to 48 hours to propagate globally, depending on the TTL (Time To Live) values and caching by DNS servers.

What are the most common DNS record types?

The most common DNS record types are A (IPv4 address), AAAA (IPv6 address), CNAME (alias), MX (mail server), and TXT (text information).

Can I lookup multiple record types at once?

Our tool allows you to lookup one record type at a time, but you can easily switch between different record types to check all the information you need.

Are DNS lookups case sensitive?

No, DNS lookups are not case sensitive. For example, 'example.com' and 'EXAMPLE.COM' will return the same results.

What is a TTL in DNS records?

TTL (Time To Live) is a value in DNS records that specifies how long other servers should cache the record before requesting a fresh copy from the authoritative server.

What is a DMARC record used for?

DMARC records are used to prevent email spoofing by specifying how email servers should handle messages that fail SPF or DKIM authentication checks.

How can I verify my domain's DNS configuration?

You can use our DNS lookup tool to check all important record types (A, MX, TXT, etc.) and ensure they match your intended configuration.

What is a wildcard DNS record?

A wildcard DNS record (usually denoted by *) matches any subdomain that isn't explicitly defined by another record, allowing automatic resolution of undefined subdomains.

Why might DNS lookups fail?

DNS lookups can fail due to incorrect domain names, network connectivity issues, DNS server problems, or recently expired domain registrations.

What is DNS caching?

DNS caching is the temporary storage of DNS query results on various servers and devices to speed up subsequent requests and reduce DNS server load.

How do I clear my DNS cache?

The method varies by operating system. Windows users can use 'ipconfig /flushdns', while Mac users can use 'sudo killall -HUP mDNSResponder' in the terminal.

What is a DNS zone file?

A DNS zone file is a text file that contains all the DNS records for a particular domain, including A records, MX records, and other resource records.

Can DNS affect website security?

Yes, DNS configuration plays a crucial role in website security. Proper DNS settings help prevent domain hijacking, email spoofing, and other security threats.
