ServerNet's full DNS lookup tool collects every record for a domain into one report. It is free and requires no signup.
How to use it
- Open the Toolbox section of the site and choose "Full DNS Lookup".
- Enter the domain name without
http://and withoutwww. - Read the report.
The tool queries over DNS-over-HTTPS, so results are independent of your own computer's DNS settings.
Reading the report
A and AAAA records
The server IP the domain points at. If you recently changed servers and still see the old IP here, DNS propagation has not finished.
NS records
The domain's active nameservers. If these differ from what you set at your registrar, the nameserver change has not taken effect yet.
MX records
Your mail server. If mail for your domain is not arriving, this is the first place to look — no MX record means no mail is delivered at all.
TXT records
Here you can see your SPF, DKIM and DMARC entries. If mail is landing in spam, check that you have exactly one SPF record.
Common troubleshooting scenarios
- Site will not load — check the A record; it should be your current server IP.
- No incoming mail — check the MX record.
- Outgoing mail goes to spam — check the TXT records for SPF and DMARC.
- Nothing changed after switching nameservers — check the NS record; if it is still the old one, you need to wait.

Alongside this, ServerNet offers a Network & Security check that inspects SSL certificate status, open ports, ping and DNSSEC. Fully diagnosing a domain usually takes both tools.
