DNS lookup
DNS lookup tool
Resolve a hostname's DNS records: A, AAAA, CNAME, MX, TXT, and NS. See exactly what the internet returns for it right now.
Confirm a change propagated
After you update a record, a lookup shows whether the new value is live yet, so you are not guessing during a migration.
Trace mail and verification
MX records route your email and TXT records hold SPF, DKIM, and domain verification. A lookup shows them plainly.
See what actually resolves
A hostname can point somewhere you did not expect after a CNAME change. This shows the real answer.
Keep watch
Get told when a record changes
PageWarden can watch a DNS record and alert you if it changes or stops resolving, so a broken or hijacked record does not go unnoticed.
