0Domain & network tools — common questions
What is a DNS lookup?
It shows the records that tell the internet where your website (A / AAAA), email (MX) and verification texts (TXT) live.
Why do my emails go to spam?
Often because the sending server's IP is on a blocklist, or SPF / DKIM records are missing. Check the IP here and the TXT records in the DNS tab.
What does "Could not check" mean?
Some blocklists refuse queries from busy shared servers, so that list could not answer. It does not mean your IP is listed.
Why do you ask a sum?
It stops robots from using the tools thousands of times, so they stay fast and free for everyone.
