DNS Lookup
All important DNS records in one place: A, AAAA, CNAME, MX, NS, TXT, SOA, CAA, SRV, DS, DNSKEY and PTR, with TTL values and DNSSEC diagnostics.
Frequently asked questions
- Why don’t I see the change I just made?
- DNS records are cached according to their TTL. With a TTL of 3600 the old value can stay visible for up to an hour on resolvers that already cached it. Use the DNS Propagation tool to check.
- What does NXDOMAIN mean?
- That the name does not exist in DNS. It does not mean the domain is available for registration – use the WHOIS lookup for that.
