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.
Allow list with a range of
IP addresses, distinct
IP addresses, and an
exception
Building on the previous examples, consider a situation where you want the
CEO’s computers (192.168.1.50, 192.168.1.51, 192.168.75) and all
boardroom computers (192.168.1.200-192.168.1.250) to access the
broadcast, with the exception of the public boardroom computer
(192.168.1.211). Use both allow and deny lists to create the rule as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51,
192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses,
provided they are separated by commas.
The following table lists some example deny lists.

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.
For example imagine your system is accessible on your local area network
(LAN) and you want to allow any computer on the LAN can access the stream
except your publicly-accessible boardroom (with IP address 192.168.1.211).
You can use the following deny list (leave the allow list empty) to permit all
