wget http://standards-oui.ieee.org/oui.txt

Also benefits a lot when rewritten to curl -O -compressed http://standards-oui.ieee.org/oui.txt since the download is 5.8MB (6006921 bytes) which compresses to just 1.78MB (1870156 bytes).

Note the grep, awk and python script could be replaced by:

$ (echo -n '{';sed -r -n 's/^([0-9A-B]{6})     \(base 16\)\t\t([^\r"]*)\r$/"\1FEFF": "\2", /p' oui.txt|tr -d '\n'|head -c-2;echo '}') > padded_macs.json

Or:

$ sed -r -n 's/^([0-9A-B]{6})     \(base 16\)\t\t([^\r]*)\r$/\1FFFE\t\2/p' oui.txt \
| jq -csR 'split("\n")|map(select(length>0)|split("\t")|{key:.[0],value:.[1]})|from_entries' > padded_macs.json
