DNS Lookup
Query A, AAAA, CNAME, MX, TXT, NS, SOA, SRV, CAA and PTR records over encrypted DNS-over-HTTPS, with TTL and reverse lookup.
Queries Cloudflare's encrypted DNS-over-HTTPS resolver (falls back to Google). Enter an IP address and the tool builds the reverse PTR name for you.
| Name | Type | TTL | Value |
|---|
The name resolves, but has no record of this type.
How to use the DNS lookup
- Type a domain name — or an IP address for a reverse lookup — into the box.
- Pick the record type you need, or leave it on All common types to sweep A, AAAA, CNAME, MX, TXT, NS and SOA at once.
- Press Look up and read the answers with their TTL; use Copy records to paste them into a ticket or a config file.
FAQ
Which resolver answers my query?
Cloudflare's 1.1.1.1 over DNS-over-HTTPS, which is encrypted and does not log your queries to disk. If it does not answer, the tool retries with Google's 8.8.8.8 DoH endpoint and tells you which one replied.
Why do I see an old value after changing a record?
Because of the TTL. The resolver keeps a cached copy for the number of seconds shown in the TTL column, so a change only becomes visible everywhere after the old TTL expires.
What is a PTR record?
It maps an IP address back to a name. Paste an IP and this tool builds the in-addr.arpa (IPv4) or ip6.arpa (IPv6) name and queries PTR for you — that is the record mail servers check for reverse DNS.
