This seems more like something that should be done in grub.cfg.
Something more along the lines:
if [ -s "$prefix/grub.cfg.$mac" ]; then
  source "$prefix/grub.cfg.$mac"
  exit_file
fi

for i in 8 7 6 5 4 3 2 1; do
if [ -s "$prefix/grub.cfg.${ip:1:$i}" ]; then
  source "$prefix/grub.cfg.${ip:1:$i}"
  exit_file
fi

It seems like this would be more productive than just handling this
specific case manually in C.
