Domain name records in plain terms
When DNS records are wrong or still propagating, visitors hit the wrong server and email bounces - often before anyone notices in the hosting panel.
A DNS lookup tool queries public resolvers for A, AAAA, MX, TXT, CNAME, and NS records. A free DNS lookup shows what the internet sees right now, not what you intended to save.
Run a one-time DNS check after migrations, hosting changes, or email setup. Add domains to TotalSiteControl monitoring for alerts when critical records change.

It queries public DNS for A, AAAA, MX, TXT, CNAME, and NS records for any domain and shows what resolvers return right now.
Yes. Enter any public domain and get instant results - no signup, no credit card, and no limit on one-off lookups.
Propagation can take minutes to 48 hours, and wrong A or CNAME records also block access. Run a lookup to confirm what public resolvers see for your domain now.
An A record points a hostname to an IPv4 address. A CNAME aliases one name to another. Root domains and mail often need A records rather than CNAME.
Usually minutes to a few hours, though rare cases take up to 48 hours. TTL on old records affects how quickly caches refresh worldwide.
Yes - enter any hostname such as www.yourdomain.com or mail.yourdomain.com. We query records for that exact name.
Some domains route mail through external providers with MX only on the root, or mail DNS is not configured yet. Check SPF on the same domain with our SPF Checker.
After migrations, hosting changes, or email setup. For production domains, use monitoring for alerts when critical records change.
