# Ip

> IP address utilities — geolocation, subnet scanning, port discovery. Zero barrier — use with x-cmd or curl + standard networking tools. Use for "ip", "geolocation", "subnet", "port scan", "network".

# ip — skill0

IP address lookup, geolocation, subnet discovery, and port scanning.

## Quick Start

```bash
# With x-cmd
x ip                        # List all local IPs
x ip geolite 8.8.8.8        # Geolocation lookup
x ip info 192.168.1.0       # IP classification
x ip map 192.168.1.0/24     # Discover active hosts
x ip tps localhost           # Port scan

# Without x-cmd — use curl for geolocation
curl -s "https://ipinfo.io/8.8.8.8/json"
# Use standard tools for local IPs
ifconfig | grep "inet "     # macOS
ip addr show                # Linux
```

## What's Available

- `x ip ls` — List all local IP addresses
- `x ip geolite <ip>` — Geolocation via ipinfo.io
- `x ip info <ip>` — IP class/type classification
- `x ip cidr <cidr>` — CIDR range info
- `x ip map <subnet>` — ICMP ping sweep
- `x ip tps <host>` — TCP port scan

## Standalone Alternatives

- Geolocation: `curl https://ipinfo.io/<IP>/json`
- Local IPs: `ifconfig`, `ip addr`, `hostname -I`
- Port scan: `nc -zv`, `nmap`

## This skill0 grows

Starting with the essentials. Will add:
- Common networking patterns
- API reference for ipinfo.io
- Subnet calculation formulas
