Frequently Asked Questions
What is a DNS lookup?
A DNS lookup is the process of querying DNS servers to retrieve DNS records for a domain name. These records include IP addresses (A/AAAA), mail servers (MX), name servers (NS), and more.
What DNS record types can I check?
This tool checks 7 common DNS record types: A (IPv4 address), AAAA (IPv6 address), MX (mail server), CNAME (alias), NS (name server), TXT (text records), and SOA (start of authority).
What is an A record?
An A record (Address Record) maps a domain name to an IPv4 address. It's the most common DNS record type and tells browsers which server to connect to when visiting a website.
What is an MX record?
MX records (Mail Exchange) specify the mail servers responsible for receiving email for a domain. They include a priority value to determine which server to try first.
How often do DNS records update?
DNS records have a TTL (Time To Live) value that determines how long they're cached. TTL can range from seconds to days. After the TTL expires, DNS servers fetch fresh data.
