Frequently Asked Questions

What is a DNS lookup?

A DNS lookup translates a domain name (like example.com) into its associated IP address and other DNS records. It queries the Domain Name System, which acts as the internet's phonebook.

How long does DNS propagation take?

DNS changes typically propagate within 24-48 hours, though many changes take effect within minutes. The propagation time depends on the TTL (Time To Live) value set on the records.

What are the most common DNS record types?

The most common types are: A (IPv4 address), AAAA (IPv6 address), MX (mail server), CNAME (alias), TXT (text data like SPF/DKIM), NS (nameserver), and SOA (start of authority).
