dotdig vs dnschecker.org
Both are free DNS tools. dnschecker.org checks propagation from 22 global servers — you see whether your recent record change is visible worldwide. dotdig is a browser-native dig replacement: clean formatted output for A, AAAA, MX, TXT, NS, CNAME, SOA, PTR, SRV, and CAA records, with custom resolver support and DNSSEC validation.

Frequently asked questions
What is the difference between dotdig and dnschecker.org?
dnschecker.org checks DNS propagation — it queries your domain from 22 global servers and shows whether the record has spread worldwide. dotdig is a browser-based DNS lookup tool that mimics the dig command: clean formatted output for A, AAAA, MX, TXT, NS, CNAME, SOA, PTR, SRV, and CAA records, with optional custom resolvers and DNSSEC validation. Use dotdig to inspect records in detail; use dnschecker.org to confirm a recent change is globally visible.
Can dotdig check DNS propagation like dnschecker.org?
No. dotdig queries from one resolver — your chosen nameserver or the default. It does not poll 22 global servers the way dnschecker.org does. If you recently updated a DNS record and need to confirm it is live worldwide, use dnschecker.org for propagation. Use dotdig when you need detailed record output — all fields, TTL, DNSSEC status — from a specific resolver.
Does dotdig support DNSSEC validation?
Yes. dotdig includes DNSSEC validation in its output and shows the full chain-of-trust status. dnschecker.org does not surface DNSSEC status. If you need to verify that a zone is properly signed, dotdig is the right choice.
Can I use a custom resolver in dotdig?
Yes. dotdig lets you specify any resolver — 8.8.8.8, 1.1.1.1, or your own nameserver — so you can test how a specific resolver sees your records. dnschecker.org uses its own fixed set of global servers and does not let you choose a specific resolver.
When should I use dnschecker.org instead of dotdig?
Use dnschecker.org after you change a DNS record — for example after updating an A record or switching MX servers — and want to confirm the change has propagated globally before announcing a migration or cutover. Its visual map is the fastest way to see which regions are still seeing the old value. Use dotdig for inspecting records in detail, testing custom resolvers, checking PTR/SRV/CAA types, or validating DNSSEC.
Is dotdig a dnschecker.org alternative?
They are complementary tools for different DNS workflows. dotdig replaces the terminal dig command in the browser — detailed output, more record types, DNSSEC, custom resolvers. dnschecker.org is a propagation monitor that checks global server consistency. Most developers use both: dotdig to inspect the record, dnschecker.org to confirm it is globally visible after a change.
