what data-type to use to store MAC addresses in an SQL Server database table?

I want to store MAC addresses in one of my database tables, what data-type should I use? Reading articles on google, I have seen Binary(8) mentioned a few times. Is this the correct way?

Also, this does not make sense to me, as MAC addresses are six groups of two hexadecimal digits, wouldn't you use Binary(6)?

I wouldn't use Binary at all.

I would use CHAR(12).

Though this really depends on what you use the data for - if this is for display only, you can simply use the textual representation.
