I think 0xd32227ed9a3bf7d8714590f837884286 is actually 280644455042589680170892351931054310022. Note that bash chewed your 128 bit number – the result in decimal had fewer digits than the one in hex.

Also you need to strip the ‘:’. Doing as 1 cmd:

echo $(( 0x$(/sbin/ifconfig | sed -n ‘s/://g;s/.*HWaddr \(.*\)/\1/p;T;q’) % 1000 )) | sed ‘s/^-//’
