### `asn_lookup` (~64 tokens)

Look up ASN/BGP info for an IP or ASN number. Identifies network operator, prefixes, abuse contact. Classifies as cloud/CDN/ISP/hosting/enterprise.

Input parameters:

- `query` (string, required): ASN (e.g., AS13335) or IP address

### `whois_lookup` (~50 tokens)

Input parameters:

- `domain` (string, required): Domain name to look up

### `ip_info` (~31 tokens)

Get public IP information: IPv4/IPv6, ISP, ASN, geolocation, proxy/VPN detection.

### `email_header_analysis` (~52 tokens)

Analyze email headers to trace delivery route, extract SPF/DKIM/DMARC results, detect delays and unencrypted hops.

Input parameters:

- `headers` (string, required): Raw email headers to analyze (paste the full header text)

### `subnet_calc` (~57 tokens)

Calculate subnet details from CIDR notation: network/broadcast address, host range, usable hosts, wildcard mask.

Input parameters:

- `cidr` (string, required): IP with CIDR prefix (e.g., 192.168.1.0/24)

### `security_scan` (~72 tokens)

Comprehensive security scan — runs DNS, SSL, HTTP, Email, Port, Propagation, Reverse DNS, ASN, and RDAP checks in parallel. Returns a 0-100 Health Score with A-F grade and prioritized actions.

Input parameters:

- `domain` (string, required): Domain to scan comprehensively (e.g., example.com)
