Frequently asked questions
What is a DNS lookup actually used for?
DNS translates human-readable domain names into the IP addresses computers use to actually connect — a lookup tool lets you see those records directly, which is the standard way to troubleshoot DNS propagation issues, misconfigured records, or email delivery problems.
Why would my new DNS records not show up yet?
DNS changes take time to propagate across the internet's many DNS servers — this is normal and expected, and re-checking after some time is the usual way to confirm propagation has completed.
What record types can I check?
Common types including A (IPv4 address), AAAA (IPv6), MX (mail servers), TXT (verification/SPF/DKIM records), NS (nameservers), and CNAME (aliases).
