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.
