Example uses of the Allow Directive:

# A (partial) domain-name
Allow from 10.1.0.0/255.255.0.0

# Full IP address
Allow from 10.1.2.3

# More than 1 full IP address
Allow from 192.168.1.104 192.168.1.205

# Partial IP addresses
# first 1 to 3 bytes of IP, for subnet restriction.
Allow from 10.1
Allow from 10 172.20 192.168.2

# network/netmask pair
Allow from 10.1.0.0/255.255.0.0

# network/nnn CIDR specification
Allow from 10.1.0.0/16

# IPv6 addresses and subnets
Allow from 2001:db8::a00:20ff:fea7:ccea
Allow from 2001:db8::a00:20ff:fea7:ccea/10
