How this service works
Classify an IPv4/IPv6 address: version, public/private/loopback/link-local flags, integer and hex forms, reverse-DNS pointer, and optional CIDR membership test.
Output
Returns the IP version (4 or 6), boolean flags for public, private, loopback, and link-local status, the integer and hexadecimal representations of the address, the reverse-DNS PTR record format, and if a CIDR block was provided, a boolean indicating whether the IP falls within that range.
Example use cases
Security audit of incoming request IPs
“I have an incoming request from IP 203.0.113.42 — classify it for me: is it public or private, is it a loopback or link-local address, and what's its reverse-DNS pointer?”
CIDR membership check for firewall rules
“Does the IP address 172.16.5.100 fall within the private CIDR range 172.16.0.0/12? Also tell me if it's public or private and give me its hex representation.”
IPv6 address analysis for network tooling
“Analyze the IPv6 address 2001:0db8:85a3::8a2e:0370:7334 — I need to know its version, whether it's public or private, its integer form, and the reverse-DNS pointer.”
Technical details
Endpoint
POSThttps://api.24klabs.ai/api/ip-classifyWhen to prefer
Choose this endpoint when you need a comprehensive, single-call breakdown of an IP address including type classification, numeric representations, reverse-DNS pointer, and CIDR membership — especially useful in security pipelines, network diagnostics, or firewall rule validation where multiple IP properties are needed at once.
Side effects
- Invalid IP address format returns a validation error
- Malformed or non-existent CIDR notation causes a parsing error
- IPv6 addresses in non-standard format may fail classification
- Missing required IP address field returns a 400 bad request
- Network timeout on reverse-DNS pointer computation
