How to Use DNS Record Validator
How to Use the DNS Record Validator
Step 1: Enter a Domain
Type or paste a domain name (e.g. example.com) into the input field. You can include https:// — it will be stripped automatically.
Step 2: Select Record Types
Toggle the record types you want to check:
- A — IPv4 address the domain points to
- AAAA — IPv6 address
- MX — Mail exchange servers (where email is delivered)
- TXT — Text records, including SPF, DKIM, and domain verification tokens
- CNAME — Canonical name alias to another hostname
- NS — Authoritative name servers for the domain
- SOA — Start of Authority — zone serial, refresh interval, and primary nameserver
- CAA — Certificate Authority Authorization — which CAs may issue SSL certificates
Step 3: Click Lookup
Results appear grouped by record type. Each record shows the raw data and TTL (how long resolvers cache the record).
Step 4: Copy Records
Hover any record row to reveal the copy button. Use "Copy All" to export everything at once.
Tips
- Use TXT to debug SPF, DKIM, and DMARC email authentication
- Use MX to verify mail routing before updating DNS
- Use A + AAAA together to check dual-stack (IPv4/IPv6) support
- TTL values show how long records are cached — low TTL means recent changes propagate quickly
- DNS propagation can take up to 48 hours; this tool shows the current live value from Cloudflare resolvers
