DNS Lookup
Query live DNS records for any domain — A, AAAA, MX, TXT, CNAME, NS, SOA, SRV, and CAA — resolved through Cloudflare and Google. Useful for verifying records, debugging mail delivery, and checking nameserver configuration.
About DNS records and this lookup
The Domain Name System translates human-readable names into the addresses and metadata that make the internet work. This tool queries live, authoritative DNS data through the Cloudflare and Google resolvers and returns the records with their TTLs, so you see exactly what the internet sees right now.
Each record type answers a different question: A and AAAA give a name's IPv4 and IPv6 addresses; MX lists the mail servers; NS names the authoritative nameservers; TXT holds text used for SPF, DKIM, DMARC, and domain verification; CNAME points one name at another; SOA and CAA carry zone and certificate-authority policy.
Use it to confirm a DNS change, debug email delivery, verify a domain's nameservers, or check what a record currently resolves to from a neutral vantage point.
Frequently asked questions
How do I look up the DNS records for a domain?
Enter a domain above and pick a record type (A, AAAA, MX, TXT, CNAME, NS, SOA, SRV, CAA). nettools.me queries live authoritative data through Cloudflare and Google resolvers and shows the records with their TTLs.
What is the difference between an A record and a CNAME record?
An A record maps a name directly to an IPv4 address; a CNAME maps a name to another name (an alias) that is then resolved. AAAA is the IPv6 equivalent of an A record.
