How this service works
Reverse DNS PTR lookup / Обратный DNS по IP
Output
Returns a JSON object containing the queried IP address and an array of PTR hostname records associated with it (e.g. {"ip":"8.8.8.8","ptr":["dns.google."]}).
Example use cases
Server identity verification
“I have the IP 104.26.0.0 and I want to know what hostname it resolves to via reverse DNS — can you look up its PTR record?”
Email server validation
“Check the reverse DNS PTR record for 209.85.220.41 so I can verify whether this mail server has proper rDNS configured.”
Network audit enrichment
“I'm auditing a list of IPs from our server logs — can you do a reverse DNS lookup on 185.199.108.153 to find its associated hostname?”
Technical details
Endpoint
GEThttps://it.finlandfoxvpn.shop/api/v1/ip/reverseWhen to prefer
Use this endpoint when you need to resolve a public IP address to its associated hostname via PTR (reverse DNS) record. It is ideal for network auditing, email server validation, log enrichment, and identifying the host behind an IP. Prefer this over forward DNS endpoints when you have an IP and need a hostname, not the reverse. At $0.001 USDC per call, it is cost-effective for per-IP lookups in automated pipelines.
Side effects
- No PTR record exists for the IP — returns empty ptr array
- Invalid or private IP address provided — may return error or empty result
- DNS timeout or resolution failure — no response or error status
- IPv6 address formatting issues causing query failure
- Rate limiting if too many requests are made in quick succession
