Public DNS Resolver & DoH Detection
Tell network infrastructure apart from real end users. The FindIP network-services API identifies public DNS resolvers, DoH (DNS-over-HTTPS) endpoints and infrastructure scanners, so you can classify benign tooling and reduce false positives in your fraud and abuse rules.

Why developers choose FindIP
DNS & DoH endpoints
Recognise public DNS resolvers and DNS-over-HTTPS endpoints that aren't ordinary end-user traffic.
Fewer false positives
Classify benign network tooling so it doesn't get caught in your fraud or abuse filters.
Unlimited & free
Classify every IP without rate limits or billing, across IPv4 and IPv6.
One simple REST call
Works from any language. Here it is in Python.
GET https://api.findip.net/{ip}/?token={token}
Python
import requests
ip = '8.8.8.8' # IP address to analyze
token = 'YOUR_API_KEY' # Get a free key at findip.net
data = requests.get(f'https://api.findip.net/{ip}/?token={token}').json()
traits = data['traits']
print('ISP: ', traits['isp'])
print('Connection type: ', traits['connection_type'])
print('User type: ', traits['user_type'])
print('ASN: ', traits['autonomous_system_number'], traits['autonomous_system_organization'])
# Combine these network traits with FindIP's network-services signals to
# identify public DNS resolvers, DoH endpoints and scanners.Frequently asked questions
It identifies public DNS resolvers, public DoH (DNS-over-HTTPS) endpoints and infrastructure scanners.
Resolvers and scanners are not ordinary end users; classifying them as benign network tooling reduces false positives in fraud and abuse rules.
