Allow list with distinct IP addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All
other addresses are denied access to the broadcast.
For example if your system is accessible on your local area network (LAN) and you want to make sure only the
CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow list with a range of IP addresses
Sometimes you’ll want a range of computer IP addresses to connect to your system. This may happen when
you have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to
192.168.1.100) and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to
192.168.1.250). If you only want the boardroom computers to connect to broadcasts from the system you
can specify the range of boardroom IP addresses rather than needing to type in each individual address. The
allow list looks as follows:
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous example as a range.
Allow list with a range of IP addresses and one or more specific IP addresses
Putting the first two examples together, we want to permit access to IP addresses in the range of boardroom
computers (192.168.1.200-192.168.1.250) and also want to add the desktop, laptop and tablet computers
of the CEO (IP addresses 192.168.1.50, 192.168.1.51, and 192.168.1.75, respectively). Note the first two IP
addresses are consecutive, so they can be added as a second range. Add these IP addresses to the list as
follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Your list can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny list with distinct IP addresses
Another simple allow/deny list is to use the list of known IP addresses to list specific denied IP addresses. All
other addresses are allowed access to the broadcast.
