```
### Methods
Return the bare MAC address without any delimiters.
```crystal
mac.bare # => "11bbccee4455"
```
Return the MAC address in EUI notation.
```crystal
mac.eui # => "11-bb-cc-ee-44-55"
```
Return the MAC address in hex notation.
```crystal
mac.hex # => "11:bb:cc:ee:44:55"
```
Return the MAC address in dot notation.
```crystal
mac.dot # => "11bb.ccee.4455"
```
Return the MAC address as an integer.
```crystal
mac.int # => 19498294723669
```
Return the MAC address as an array of bits.
```crystal
mac.bits # => ["0001", "0001", "1011", "1011", "1100", "1100", "1110", "1110", "0100", "0100", "0101", "0101"]
