Resolve IP addresses to hostnames (PTR records) in bulk, fast, over DNS-over-HTTPS. Works with IPv4 and IPv6. No API key, no proxy.
What it does
Give it a list of IPs and get the hostname each one points to (its PTR record) — the reverse of a normal DNS lookup. Great for making raw IPs human-readable at scale.
Use cases
- Log & traffic enrichment — turn server/firewall logs of IPs into readable hostnames.
- Network mapping — see what lives behind a range of IPs.
- Security & threat hunting — spot suspicious or unexpected hosts.
- Email deliverability — check that a sending IP has a valid PTR (rDNS), which mail servers require.
Input
| Field | Type | Description |
|---|---|---|
ips | array | IP addresses to look up (IPv4 or IPv6), e.g. ["8.8.8.8", "1.1.1.1", "2606:4700:4700::1111"]. |
Example input
Output
If an IP has no PTR record, found is false and hostname is null.
Export to JSON, CSV, Excel or Google Sheets, or pull it via the Apify API.
Tips
- Send thousands of IPs in one run — it batches automatically.
- Pair it with an IP-geolocation or ASN Actor to fully enrich your logs.
FAQ
Do I need a key? No. No proxy either — it uses public DNS-over-HTTPS.
IPv6 supported? Yes, both IPv4 and IPv6.
How am I charged? Pay per result (per IP resolved).
