FAQ

What is DNS?

DNS stands for Domain Name System. It's like the internet's phone book, translating human-readable domain names (like www.example.com) into IP addresses that computers use to identify each other.

Why would I need to use a DNS Lookup Tool?

You might use a DNS Lookup Tool to troubleshoot email delivery issues, verify domain ownership, check for DNS propagation after making changes, or investigate website connection problems.

Are DNS Lookup Tools safe to use?

Yes, DNS Lookup Tools are generally safe as they only query publicly available information. However, be cautious about entering sensitive domain names on public tools if you're concerned about privacy.

How often do DNS records update?

DNS records update based on their Time-to-Live (TTL) value, which can range from a few minutes to several days. Changes to DNS records may take time to propagate globally.
