# IP Address Parser MCP for AI Agents AI Agent Connect

> IP Address Parser validates and classifies IPv4 and IPv6 addresses with production-grade accuracy. It handles CIDR notation, detects private versus public ranges, and converts between IPv4 and IPv6 formats. Built on the industry-standard ipaddr.js library, it ensures your agent handles networking data with the same precision as Express.js or Koa. It is designed for high-stakes environments where guessing a network range isn't an option.

## Description

Imagine you're trying to figure out if a specific IP address belongs to an internal private network or if it's actually poking out onto the public internet. If you ask a standard model to do this, it might guess based on patterns it saw during training, but it won't be checking the actual RFC standards. This Connector gives your agent the ability to perform precise, real-time network analysis. Instead of guessing, your agent can now confirm whether an address is a loopback, a multicast, or a link-local address instantly. It can also take a CIDR block and break down the network address and prefix length without breaking a sweat. This is the same logic used by the heavy hitters in the web development world, so you know the data's solid. When you connect this through the Vinkius catalog, you're giving your agent a reliable way to handle infrastructure logs, security audits, and network configuration tasks. You stop worrying about whether the model is hallucinating network ranges and start getting accurate data for your security workflows. It's about moving from "I think this is internal" to "I know this is internal."

## Tools

### parse_ip_address
Validates and parses IPv4/IPv6 addresses to identify their range and type. It handles CIDR notation and converts between IPv4 and IPv6 formats.

## Prompt Examples

**Prompt:** 
```
I have a list of IPs from a security alert: 192.168.1.1, 8.8.8.8, and 10.0.0.5. Which of these are internal?
```

**Response:** 
```
Here is the classification for those IPs:

| IP Address | Kind | Range | Status |
| :--- | :--- | :--- | :--- |
| **192.168.1.1** | ipv4 | private | Internal RFC 1918 address. Not routable on the public internet. |
| **8.8.8.8** | ipv4 | public | Publicly routable address. |
| **10.0.0.5** | ipv4 | private | Internal RFC 1918 address. Not routable on the public internet. |
```

**Prompt:** 
```
Check the subnet 172.16.0.0/12. Is it a private range?
```

**Response:** 
```
Yes, that is a private range.

**Details:**
* **Network:** 172.16.0.0
* **Prefix:** /12 (65,536 hosts)
* **Kind:** ipv4
* **Range:** private

This falls within the RFC 1918 private space.
```

**Prompt:** 
```
Convert 192.168.1.100 to an IPv6-mapped address.
```

**Response:** 
```
The IPv6-mapped representation for your address is:

`::ffff:192.168.1.100`

**Details:**
* **Kind:** ipv4
* **Range:** private
* **Mapped IPv6:** ::ffff:192.168.1.100
```

## Capabilities

### Classify IP types
Identify if an address is private, public, loopback, multicast, or link-local.

### Parse CIDR blocks
Break down network notation into addresses and prefix lengths.

### Convert IP formats
Transform IPv4 addresses into their IPv4-mapped IPv6 representations.

### Detect dual-stack formats
Automatically recognize and handle both IPv4 and IPv6 address types.

### Validate network strings
Check if an IP string follows official RFC standards for networking.

## Use Cases

### Firewall Log Audit
A security pro asks the agent to scan a list of IPs from a firewall alert to see which ones are internal and which are external threats.

### VPC Subnet Verification
A DevOps engineer wants to verify that a new VPC subnet range doesn't overlap with existing private blocks during a migration.

### Dual-Stack Migration
A developer needs to convert a list of old IPv4 addresses into IPv6-mapped formats for a new server setup.

### Data Cleaning for Analysts
An analyst wants to strip out non-routable addresses from a messy CSV of network data to clean up a report.

## Benefits

- Stop worrying about hallucinations by using the same library that powers Express.js for network validation.
- Instantly identify if an IP is private, loopback, or multicast without having to look up RFC tables manually.
- Handle both IPv4 and IPv6 seamlessly so your agent won't trip over dual-stack configurations.
- Convert between IPv4 and IPv6 mapped addresses to keep your infrastructure documentation consistent.
- Quickly extract network prefixes and host counts from CIDR blocks for faster subnet planning.

## How It Works

The bottom line is you get production-grade network validation instead of AI guesswork.

1. Provide your agent with an IP address or a CIDR block string.
2. The Connector processes the string using the production-grade ipaddr.js engine.
3. Your agent receives a structured breakdown of the range, type, and format.

## Frequently Asked Questions

**Can the IP Address Parser tell me if an IP is private?**
Yes, it identifies if an address is private, loopback, or multicast based on official RFC standards. This helps you quickly distinguish between internal and external traffic.

**Does IP Address Parser support both IPv4 and IPv6?**
It handles both formats automatically. This makes it a great choice for modern networks that use dual-stack configurations.

**Can I use IP Address Parser to check CIDR blocks?**
You can pass a CIDR like 10.0.0.0/8 and it will return the network address and prefix length. It's perfect for verifying subnet masks.

**Will IP Address Parser help me with firewall logs?**
It's ideal for that because it can quickly classify thousands of IPs to see which ones are internal. It saves you from manually checking every entry.

**Does IP Address Parser provide geolocation?**
No, it focuses on technical classification like range type and format. It does not provide physical location data like city or country.

**Is IP Address Parser accurate for production use?**
Yes, it uses the same ipaddr.js library that powers Express.js. This ensures the classification is accurate and follows networking standards.

**How does it know if an IP is private or public?**
It follows the IANA reserved ranges defined in RFC 5735 (IPv4) and RFC 4291 (IPv6). 10.x.x.x, 172.16-31.x.x, and 192.168.x.x are classified as 'private'. 127.x.x.x as 'loopback'. Everything else as 'unicast' (public).

**Can I check if an IP belongs to a specific CIDR range?**
Yes. Pass the CIDR notation like '10.0.0.0/8' and the engine returns the network address, prefix length, and address kind. Parse both the IP and the CIDR to compare.

**Does it work with IPv6 addresses?**
Yes. Full IPv6 support including compressed notation (::1), IPv4-mapped (::ffff:192.168.1.1), and all RFC 4291 scoped addresses.
