DNS Lookup
Query DNS records for a hostname or domain.
What is DNS Lookup?
A DNS lookup queries the Domain Name System for records that map hostnames to addresses, mail exchangers, text policies, and other service data.
How it works
Enter a hostname and choose the record types you need. PacketWizard queries resolvers and returns structured answers you can copy into tickets or change plans.
Common issues
No records found
Confirm the hostname spelling, try the apex domain, and check whether the zone is delegated. NXDOMAIN and empty answers mean different things.
Stale answers after a change
TTL caching can delay visibility of DNS updates. Compare multiple resolvers and wait for TTL expiry when validating a cutover.
Frequently asked questions
Which DNS records should I check first?
Start with A/AAAA for reachability, MX and TXT for mail, and CNAME/NS when diagnosing aliases or delegation problems.
Can DNS problems look like outages?
Yes. Clients that cannot resolve a name never reach an otherwise healthy server. Pair DNS Lookup with HTTP and TLS inspectors when websites fail intermittently.
