I agree with you.  02:04:06:08:0a-length-3 (or another agreed textual
representation of blocks) is a brief way to express these 4 addresses.

For the textual representation of MAC address blocks I was thinking like
of the IPv6 style 02:04:06:08:0a/plen, but that would be longer to
express just these 4 addresses.
