Hi.
Currently I have a table:
1. MAC address defined as BIGINT
2. MAC address set as primary key
Should I consider changing it to CHAR(12)?
Replies will be appreciated.

Hi
It depends. You may convert the MAC address to a decimal integer and store
it as a BIGINT. Use UNSIGNED as well; there are no negative numbers
involved. This may gain some speed and saves storage space.
The drawback I can see is that these numbers are not human readable, but
you may convert back to HEX when retrieving data.
And it may break when they start using larger MAC addresses eventually.
