Frequently asked questions

What is a DNS lookup?

It is the query that translates a domain name into technical information such as the server's IP address, mail servers (MX) and other records configured in the DNS zone.

Which DNS record types can I look up?

You can query A and AAAA records (IPv4 and IPv6 addresses), MX (email), TXT (including SPF, DKIM and DMARC), NS (name servers), CNAME (aliases) and more.

What is an MX record?

The MX (Mail Exchange) record specifies which servers are responsible for receiving a domain's email. It is essential for diagnosing message delivery issues.

Why does my DNS still show old values?

DNS changes take time to propagate because of TTL (cache time). Full propagation can take from a few minutes to 48 hours depending on the configuration.

What are SPF, DKIM and DMARC records?

They are TXT records used to authenticate email and prevent spoofing. They help improve deliverability and protect the domain against spam and phishing.
