# Mac6
[](https://travis-ci.org/ggiamarchi/mac6)
`mac6` is a simple CLI that compute a link local IPv6 address from a given MAC address.
## Usage
```
Usage: mac6 [ -i= ] MAC
Compute IPv6 link-local address from MAC address
Arguments:
MAC Mac address
Options:
-i, --interface Out interface to build IPv6 link local string
```
## Examples
1. Getting the link-local IPv6 address from a MAC address
```bash
$ mac6 8b:7a:1b:06:06:75
fe80::897a:1bff:fe06:0675
```
2. Getting the link-local IPv6 address from a MAC address with the out interface
```bash
$ mac6 -i eth0 8b:7a:1b:06:06:75
fe80::897a:1bff:fe06:0675%eth0
```
## Main use case
The initial idea for this project is to ease connecting to a machine having an IPv6 stack. Today most of the
Linux distribution comes with a dual IP stack. So, even when working on a legacy IPv4 network, it' possible to
connect to any other machine using it's IPv6 link-local address. It can be usefull for instance to connected
to a machine that failed its DHCP request.
When you know the machine's MAC address, you can use `mac6` to contact a machine through it's IPv6 link-local
address.
__Examples__
```
$ ping6 $(mac6 -i eth0 8b:7a:1b:06:06:75)
```
is equivalent to
```
$ ping6 fe80::897a:1bff:fe06:0675%eth0
```
And
```
$ ssh user@$(mac6 -i eth0 8b:7a:1b:06:06:75)
```
is equivalent to
```
$ ssh user@fe80::897a:1bff:fe06:0675%eth0
```
