How long DNS servers remember a record. Until it runs out, they return the old value. Before moving a site, lower the TTL to 5 minutes in advance.

How long to wait after changing DNS?

Usually from a few minutes to a day, depending on the TTL of the old records. Changing name servers at the registrar can take up to 48 hours.

Why do Google and Cloudflare answers differ?

Most often one of them still remembers the old record, so wait for the TTL to run out. Also, big sites return different IPs in different places to send you to the nearest server, so for them a difference is normal.

How do I check SPF and DMARC?

Choose "All" or TXT. We'll find the SPF record among the TXT records, check the DMARC record at _dmarc.domain separately, and show whether they exist.

What is a PTR reverse record?

A name tied to an IP address. Enter an IP and we'll build the right query and show the name. Mail servers must have a PTR record.

Are my lookups stored anywhere?

No. The lookup goes straight from your browser to Google and Cloudflare DNS, our server isn't involved.

Types of DNS records

A and AAAA point to the site's IP address, CNAME makes a domain an alias of another name, MX tells where to deliver mail, NS says which servers are responsible for the domain. TXT holds ownership checks and mail rules, CAA lists the authorities allowed to issue SSL certificates.

SPF and DMARC: why emails end up in spam

SPF is a TXT record listing the servers allowed to send mail for the domain. DMARC (a record at _dmarc.domain) tells mail services what to do with emails that fail the check. Without them, emails from your domain land in spam more often and scammers can fake the sender more easily.

Changed DNS and the site won't open

New records don't spread worldwide instantly: servers keep the old answer until the TTL runs out. Comparing Google and Cloudflare shows whether big DNS providers already see the new values. If the answers differ, wait for the time shown in the TTL. Big sites may always return different addresses because they send you to the nearest server.
