Block or allow multiple IP addresses on one line Using htaccess

Save a little space by blocking multiple IP addresses or ranges on one line. Here are few examples (edit values to suit your needs):

# block two unique IP addresses
deny from 99.88.77.66 11.22.33.44
# block three ranges of IP addresses
deny from 99.88 99.88.77 11.22.33

Likewise, to allow multiple IP addresses or ranges on one line:

# allow two unique IP addresses
allow from 99.88.77.66 11.22.33.44
# allow three ranges of IP addresses
allow from 99.88 99.88.77 11.22.33
