DNS Lookup: Read Domain Records
When company emails stop arriving, DNS records may hold the cause. This tool queries A, MX, and TXT records server-side. MX shows mail routing, TXT shows verification. Query only your own or public domains.
Step by step
- Type the domain correctly with extension.
- Check MX records first for mail routing.
- Review A and AAAA for server addresses.
- Look for verification text in TXT records.
- Save the result for support, query again later.
Example scenario
A nonprofit's emails stop. The admin sees MX records still point to the old provider and SPF is missing from TXT. She sends findings to support, fixes routing, and re-queries to confirm.
Check your result
Read record types carefully: A is IPv4, AAAA IPv6, MX mail server, TXT verification. With several MX records check priorities. Results may be cached; wait and re-query.
