Discover SLAAC IPv6 neighbors and resolve their names via mDNS (Avahi)

SLAAC Resolver

Discover SLAAC-configured IPv6 neighbors and resolve their mDNS names using Avahi.

Overview

This tool scans a given network interface for IPv6 neighbors discovered via SLAAC, and attempts to resolve their names using avahi-resolve-address. It can be used both as a command-line utility and as a Python library.

Installation

Clone the repository and install it in editable mode:

git clone https://github.com/cjuniorfox/slaac-resolver.git
cd slaac-resolver
pip install -e .

This will make the slaac-resolver command available on your system.

Usage

Command-Line Interface

slaac-resolver <interface> [--log-level <LOG_LEVEL>]

. --log-level is optional. Possible values: DEBUG, INFO, WARNING, ERROR, CRITICAL. Default is INFO.

Example:

slaac-resolver br0 --log-level DEBUG

The output is a JSON list of resolved neighbors, like:

[
  {
    "hostname": ["mydevice", "local"],
    "ipv6": ["fe80", "", "abcd", "1234", "5678", "9abc", "def0", "1234"]
  }
]

Python Library

You can also use the resolver in your Python code:

from slaac_resolver import get_ipv6_neighbors

neighbors = get_ipv6_neighbors("br0", log_level=logging.DEBUG)
print(neighbors)

Requirements

• Python 3.7+
• ip command (from iproute2)
• avahi-resolve-address (part of avahi-utils)
