View the DNS records of a domain.

What are DNS records?

DNS is the address book of the internet. For each domain it lists which IP address the website points to (A and AAAA), which server receives the mail (MX), which name servers manage the domain (NS) and separate lines of text for verification and mail security (TXT).

What are SPF and DMARC for?

Without those two, anyone can send mail that appears to come from your domain. SPF is the list of servers that may send mail for your domain. DMARC tells the receiver what to do with mail that does not check out: let it through, move it to spam or reject it.

What does the TTL mean?

The TTL is the number of seconds an answer may be remembered. Here you see the time remaining at our server. After a change it can therefore take a while before everyone sees the new record.

I changed a record but still see the old one

That is because of the TTL above. Wait until the old value has expired. For most domains that is within an hour, sometimes a day.

SPF or DMARC is missing on my domain

You set both as a TXT record at the company that holds your domain. What goes in depends on who sends your mail, such as Microsoft 365. Rather have it done? Vienix sets up Microsoft 365 and the DNS records that go with it.
