Title: i'd use the following

Comment:
^(?i:(?:[0-F]{2}[-:]?){5}[0-F]{2})$
shorter, only matches the full mac address, allows delimiter-less or ":" and "-".
if you set the "i" modifier outside, just
^(?:[0-F]{2}[-:]?){5}[0-F]{2}$
is enough
Title: optional and different delimiter
Name: Clemens Gruber

Comment:
this expression permits to use a delimiter or not (optional) -> [- :]? the question mark at the end and secondly permits different haracters as delimiter -> [- :]
^([0-9a-fA-F][0-9a-fA-F][- :]?){5}([0-9a-fA-F][0-9a-fA-F])$
