Add IP Security & Reputation Services

[Ricky-G]

Description

Implement IP security and reputation services to provide threat intelligence and security-related information about IP addresses.

Requirements

1. Threat intelligence integration: Check IPs against malware, botnet, and spam databases
2. VPN/Proxy/Tor detection: Identify anonymization services and proxy types
3. Abuse contact lookup: Return abuse contact information for IP networks
4. Risk scoring: Provide comprehensive security risk scores
5. Blacklist checking: Check against major security blacklists
6. Network type classification: Identify residential, business, mobile, hosting, etc.
7. Security reputation: Historical security events and reputation data

API Endpoints

• GET /api/ip/security - Get security information for client IP
• GET /api/ip/{ipAddress}/security - Get security information for specific IP
