Realistically, it isn't 128 bits.

64 bits off the bottom are used for the EUI.
8 or 16 bits in the middle are used for local topology.
3 bits off the top are used for format specifier.

So, it is actually 45 or 53 bits.

Generally, the two are intertwined.  If you don't care about routing,  
pick a number at random.  They're just integers after all.
