About this DNS Lookup tool
Look up any DNS record type for any domain. CheckHub queries Google Public DNS and Cloudflare 1.1.1.1 over DNS-over-HTTPS for accurate, real-time answers without depending on your ISP cache.
How to use the DNS Lookup
- Step 1. Enter a domain name (e.g. example.com).
- Step 2. Pick a record type — A, AAAA, MX, TXT, and more.
- Step 3. Read the resolver, TTL, and full answer set in the response table.
Frequently asked questions
- What is a DNS lookup?
- A DNS lookup translates a domain name into the records that tell browsers and mail servers where to connect, such as IP addresses (A/AAAA), mail servers (MX), or text policies (TXT).
- Why do I see different results from my computer?
- Local DNS resolvers cache records based on their TTL. CheckHub queries authoritative public resolvers directly so it can show you the freshest answer instead of a stale cached one.
- Is DNS-over-HTTPS more accurate?
- DoH bypasses ISP-level interception and caching, so the answer matches what the public resolver actually returns at that moment. CheckHub uses both Google and Cloudflare DoH for redundancy.
